A Practical Budget for Tinting Your Car—Without Comparing Apples to Oranges

By Andre Silva · 10 August 2026 · 22 min read

The short answer: a realistic car-window tint budget

For most ordinary cars, a sensible starting budget for professional window tinting is about $150–$600. A Maryland installer publishes that range for most vehicles, but it should be treated as a regional planning estimate—not a statistically representative national average, a guaranteed quote, or proof that an equivalent package costs the same everywhere. See the Maryland provider’s pricing qualifications.

Limited coverage can cost less. Tinting only the two front side windows is commonly quoted at about $80–$200, although some regional estimates for partial work reach $250. Premium film, a large vehicle, specialty glass, windshield or roof coverage, old-film removal, or a labor-intensive luxury vehicle or EV can push the total beyond $1,000. Review the Spokane provider’s front-window and full-vehicle ranges.

For initial planning, use three broad bands:

Approximately $100–$300: limited coverage, entry-level film, or a relatively simple small vehicle.
Approximately $300–$600: many mainstream professional side-and-rear packages.
Approximately $600–$1,200 or more: premium film, extensive coverage, large vehicles, or complex glass.

A Michigan installer publishes the same entry-level, mid-range, and premium bands while emphasizing that the vehicle, selected film, and customization determine the actual price. Review the Michigan installer’s planning bands.

The most important qualification is that “full car” or “full vehicle” is not a standardized package. A common definition is all side windows plus the rear windshield, but another quote may cover a different number of panes. The front windshield, visor strip, sunroof, panoramic roof, old-film removal, taxes, supplies, and other charges may be separate.

Job scope	Directional range	Common exclusions or variables
Two front side windows	$80–$200, sometimes up to $250	Existing-film removal, premium film, difficult glass, taxes
Budget side-and-rear package	$100–$300	Windshield, roof glass, removal, fees
Mainstream professional package	$300–$600	Windshield, panoramic roof, old-tint removal
Premium or complex package	$600–$1,200+	Exact coverage, specialty glass, extensive preparation
Full-windshield add-on	$100–$300 where lawful	Windshield size, access, film line, existing film
Panoramic-roof add-on	$150–$400	Panel size, curvature, preparation, multiple sections

The package bands come from the Michigan estimate above; the front-window figure appears in the Spokane guide, while the windshield and panoramic-roof ranges are published in a detailed San Antonio pricing guide. See the San Antonio add-on definitions.

These are synthesized commercial estimates from regional tint providers. They are useful when answering “how much does it cost to tint car windows?” at the budgeting stage, but they are not independently measured national averages. A useful local quote still requires your year, make, model, selected film, and exact coverage.

Before comparing prices, ask each shop to define its package in writing. A lower quote covering fewer panes is not necessarily cheaper than a higher quote that includes additional fixed glass, removal, preparation, and stronger written warranty terms.

Cost by film type: dyed, carbon, ceramic, and premium films

Film categories provide a useful starting point, but they do not fully identify a product. Manufacturers can sell several lines within the same category, and those lines may differ in construction, documented specifications, appearance, price, and warranty terms.

Film tier	Directional installed range	Typical market position
Dyed	About $100–$300	Budget tier
Carbon	About $200–$650	Middle tier
Ceramic	About $350–$1,000+	Premium common tier
Premium multilayer, crystalline, or infrared-focused film	About $400–$800+, potentially $1,200–$1,500 for large or complex work	High-end or specialty tier

These normalized ranges draw on several commercial estimates. A product vendor lists dyed film at $100–$300, carbon at $250–$800, and ceramic at $350–$1,000; its higher carbon ceiling illustrates how vehicle size, coverage, and product line can blur category boundaries. Compare the vendor’s film-price ranges.

Dyed film is usually the least expensive category. It can be a reasonable choice when appearance, privacy, or a modest initial budget is the priority. Choosing the budget film tier does not automatically mean accepting poor workmanship; product selection and installation quality are separate decisions.

Carbon film generally occupies the middle of the market. It may appeal to buyers who want to move beyond an entry-level product without paying for a shop’s premium ceramic line. Prices overlap because a higher-priced carbon product on a large vehicle can cost more than an entry-level ceramic package on a compact car.

Ceramic film is commonly positioned as the premium mainstream option. The higher price may reflect the exact product, a flagship manufacturer line, installer authorization, warranty administration, labor, or local market positioning. Ceramic is not automatically the best value for every owner. Its case is stronger when the documented specifications of a particular product align with the owner’s climate, parking habits, driving time, desired appearance, and expected ownership period.

For a concrete regional example, a Spokane provider lists full-vehicle prices excluding the windshield at $150–$300 for dyed film, $200–$400 for carbon, $300–$600 or more for ceramic, and $400–$800 or more for crystalline or infrared-focused film. Those are local commercial estimates rather than universal prices. See the Spokane package definitions and film ranges.

A detailed San Antonio table shows why broader ceramic estimates can climb higher. Its side-and-rear ceramic packages range from $350–$550 for a compact sedan to $600–$1,000 for a luxury vehicle and $500–$1,200 or more for Tesla models. The standard package excludes windshield strips, panoramic roofs, and old-tint removal. Examine the San Antonio vehicle-by-film table.

At the broadest end of the available estimates, multilayer ceramic packages can reach $700–$1,500. That ceiling should not be applied automatically to an ordinary sedan: it reflects the possible combination of premium film, larger or specialty vehicles, and extensive coverage. Review the calculator’s film-tier ranges and qualifications.

Published ranges overlap for several reasons:

Some apply to compact sedans, while others include SUVs, luxury vehicles, or EVs.
Some are advertised starting prices rather than likely out-the-door totals.
“Full vehicle” may describe different pane counts or coverage.
Windshields and roof glass may be included, excluded, or left undefined.
A category name does not identify the manufacturer or exact product line.
Regional labor rates and shop positioning differ.
Removal, preparation, warranty coverage, taxes, and other charges may be handled separately.

Do not compare products using category-wide performance claims alone. Ask for the manufacturer and exact film line, then request the corresponding specification sheet and written warranty. Product-specific documentation is more useful than assuming every film labeled “ceramic” or “carbon” performs identically.

Finally, darkness is not the same as film technology. Dyed, carbon, and ceramic products can each be sold in several shades. Selecting a lower visible-light-transmission level does not automatically mean selecting a more expensive technology.

Cost by vehicle type and glass complexity

The vehicle affects both material use and labor. Larger vehicles often require more film, but exterior size and passenger capacity are not the only variables.

Use the following as broad, nonbinding planning ranges across multiple film tiers and package definitions:

Vehicle type	Broad directional range across film tiers
Coupe	Roughly $150–$700
Sedan	Commonly about $150–$600
Truck	Roughly $200–$900
SUV or crossover	Roughly $250–$1,100
Luxury vehicle or EV	Roughly $400–$1,500+

A commercial tint calculator publishes $180–$700 for coupes, $150–$600 for sedans, $200–$900 for trucks, $250–$1,100 for SUVs, and $400–$1,500 or more for luxury vehicles and EVs. The slightly lower coupe floor in the table reflects a separate Spokane estimate, and neither source presents these bands as guaranteed quotes. Review the calculator’s vehicle ranges.

Those broad bands span several film tiers and coverage definitions. They do not predict that every SUV will cost $1,100 or every EV will cost at least $400. A two-window truck job, for example, is not comparable with tinting every side pane and the rear glass on a crew-cab truck.

Narrower local examples may be more useful for an initial comparison. One Spokane guide lists:

Four-door sedan: $200–$500
SUV or crossover: $250–$600
Truck: $250–$550
Minivan: $300–$650

These figures are regional provider estimates, and the guide expressly says that film, vehicle, window complexity, and geographic market affect the final price.

Window count and total glass area matter, but installers may also account for features such as:

A steep or compound-curved rear windshield requiring careful film shrinking
Panoramic or multi-panel roof glass
Oversized side or rear windows
Frameless door glass
Numerous small fixed panes
Deep interior trim or restricted access to glass edges
Existing film, adhesive, or contamination
Rear defroster lines requiring cautious preparation
Large patterns that are difficult to position and handle

Coupes demonstrate why pane count alone can mislead. A two-door vehicle may have fewer windows than a sedan, but longer doors, frameless glass, or a difficult rear windshield can offset the material savings. Minivans may have relatively straightforward shapes but a large total glass area and more individual panels. Trucks range from simple regular-cab layouts to crew cabs with several side panes and powered rear sliders.

Luxury vehicles and EVs also require model-specific treatment. A higher quote may reflect large glass areas, roof panels, frameless windows, access constraints, or the installer’s assessment of labor and risk—not merely the vehicle’s price or powertrain.

Owner-reported Rivian prices illustrate the importance of scope. One R1S owner reported $420 for ceramic film around the vehicle, plus $180 for the windshield and $200 for the glass roof, producing an $800 total. Another reported $610, but the scope was not fully itemized. These are anecdotes about particular Rivian installations, not representative EV prices. Read the Rivian owner reports and limitations.

For a useful local estimate, provide the shop with:

Model year
Make and exact model
Body style or cab configuration
Whether film is already installed
The exact panes to be covered
Whether the windshield or roof glass is included
The film manufacturer, product line, and shade under consideration

Photos may help a shop identify existing tint, unusual fixed panes, roof configuration, or access issues. The installer may still need to inspect the vehicle before confirming removal work or a final price.

What a full-vehicle quote includes—and what usually costs extra

A common professional package covers all side windows plus the rear windshield, while excluding the front windshield and roof glass. That is a useful working definition, not an industry-wide standard. Never assume “full car,” “complete tint,” and “all around” describe identical coverage.

A shop may distinguish between movable door windows, fixed quarter windows, rear cargo-area panes, and the rear windshield. Ask for a written pane-by-pane list or coverage diagram rather than relying on the package name.

Limited front-window work commonly costs about $80–$200, with some regional partial-coverage estimates reaching $250. See the Florida guide’s partial-coverage range.

Common add-ons include:

Add-on	Directional range	What can change the price
Old-tint removal	$50–$150	Number of panes, film condition, adhesive residue, defroster lines
Windshield visor strip	$50–$100	Width, shape, selected product
Full-windshield film	$100–$300 where lawful	Windshield size, access, film line, existing film
Sunroof tint	About $50–$200	Panel size and number of sections
Panoramic-roof tint	$150–$400	Large area, curvature, preparation, multiple panels

The removal, windshield, and sunroof ranges are also reflected in a commercial tint calculator, which lists $50–$150 for old-tint removal, $60–$300 for windshield film, and $50–$200 for sunroof film.

Removal deserves particular attention. The common $50–$150 range is therefore a planning allowance, not a guaranteed cap.

Other supported quote modifiers include:

Mobile installation
Premium-dealer or premium-shop pricing
A higher-tier product
Additional warranty coverage
Difficult adhesive removal
Extra preparation
Oversized, curved, or difficult-to-access glass
Specialty windshield, sunroof, or roof applications

Taxes, supplies, disposal, preparation, and similar charges are not consistently addressed in the published provider guides. Rather than assuming they are included or typical, ask whether the quoted number is the final out-the-door total and request written disclosure of anything excluded.

A concise coverage checklist can prevent most misunderstandings. Send the same list to each shop and ask it to mark every item as included, excluded, or optional:

Front driver and passenger side glass
Rear side-door glass
Fixed quarter or cargo-area windows
Rear windshield
Windshield visor strip
Full front windshield
Sunroof
Panoramic or multi-panel roof
Removal of existing film and adhesive
Taxes, supplies, disposal, and other disclosed fees

Also ask whether the price is based on each individual piece of glass or on a broader opening or vehicle section. What appears visually to be one rear-side area may contain more than one pane, affecting the work required.

Why two shops can quote very different totals

Two quotes carrying the same broad label can describe materially different jobs. To compare them fairly, separate seven variables.

1. Exact film manufacturer and product line

“Dyed,” “carbon,” and “ceramic” are categories, not complete product identities. A manufacturer may sell entry-level and flagship lines within the same category, each with different documented specifications and warranty terms. If a quote does not identify the manufacturer and line, the product cannot be verified.

2. Vehicle size

More glass generally requires more material. SUVs, minivans, crew-cab trucks, and vehicles with large rear areas may therefore cost more than compact sedans. Size matters, but it should not replace an assessment of the actual glass layout.

3. Number of glass panels

Vehicles with similar exterior dimensions can have different pane counts.

4. Glass shape and access

A curved rear windshield can require more shrinking and handling than a flat door window. Frameless windows, tight seals, deep trim, oversized panels, and restricted interior access can increase labor even when the amount of film is modest.

5. Preparation or removal work

Removing existing film and adhesive is a separate task. Ask how the shop calculates removal and what conditions could change the estimate after inspection.

6. Installer labor and credentials

Labor prices can reflect experience, shop overhead, installation conditions, local demand, and the time budgeted for preparation and finishing. Installer authorization may matter to a particular product warranty, but a credential alone does not guarantee flawless work. Evaluate the process, recent comparable examples, written policies, and defect-handling procedure.

7. Local market

Commercial rent, wages, competition, and regional demand affect pricing. A promotional starting price in one city should not be treated as a national benchmark.

Material upgrades and labor premiums should be separated. Paying more for another film line is not the same as paying for adhesive removal, specialty glass, or a difficult rear windshield. Ask the shop to identify each component.

Warranty terms can also explain a price difference, but “lifetime warranty” is not a complete description. Confirm:

Which defects are covered
Whether fading, color change, bubbling, peeling, or adhesive failure is addressed
Whether replacement film and labor are both included
Whether accidental damage or glass breakage is excluded
Whether proof of purchase is required
Whether coverage transfers to another owner
Whether installer authorization is required
Who pays for removal and reinstallation

Darkness, normally expressed as VLT, is a separate characteristic from film technology. A lower-VLT shade is not automatically a higher technology tier or the main reason one quote costs more.

The lowest advertised number may be a starting price for a small vehicle, selected windows, or entry-level film. Once additional panes, removal, specialty glass, and disclosed fees are included, it may no longer be the lowest out-the-door total.

Use this equivalent-scope formula:

Same vehicle + same named film product + same VLT + same panes + same removal scope + same warranty basis + all taxes and fees = a meaningful comparison

If one of those components changes, record the difference before deciding which quote offers better value.

Sample budgets: from a basic sedan to a complex premium job

The following scenarios are illustrative calculations, not national averages or actual quotes. They demonstrate how coverage and add-ons affect a budget so you can substitute local figures.

Scenario 1: Budget sedan

Assume a sedan owner wants dyed film on the side windows and rear glass:

Base dyed package: $150–$300
Old-tint removal: $0, assuming bare glass
Windshield or roof work: $0
Taxes and other fees: not yet known

Illustrative subtotal: $150–$300 before taxes or other fees.

The package range corresponds to a Spokane provider’s full-vehicle dyed estimate, which excludes the windshield. The owner should still confirm every included pane, the exact film, and the written warranty.

Scenario 2: Mid-range sedan with removal and windshield film

Assume a carbon side-and-rear package, old-film removal, and full-windshield film where lawful:

Carbon package: $250–$450
Removal: $100
Full windshield: $200

Arithmetic:

Low example: $250 + $100 + $200 = $550
High example: $450 + $100 + $200 = $750

Illustrative subtotal: $550–$750 before taxes or other fees.

The carbon range falls within detailed San Antonio sedan estimates, while the removal and windshield amounts are mid-range illustrative selections from that provider’s add-on bands. The windshield should be itemized by product and VLT rather than assumed to be part of “full-car” tint.

Scenario 3: SUV or crossover

Detailed San Antonio examples place a side-and-rear package for an SUV or crossover at approximately:

Carbon: $350–$500
Ceramic: $500–$800
Roof glass: not included
Existing-film removal: not included

Illustrative subtotal: $350–$800 before roof work, removal, taxes, or other fees.

The range is wide because film category is only one variable. Total glass area, individual pane count, rear-window shape, installer, and exact product line also matter.

Scenario 4: Two-front-window match

Assume the owner wants only the front driver and passenger windows tinted:

Two front side windows: $80–$200
Removal: $0, assuming bare glass
Other charges: not yet known

Illustrative subtotal: $80–$200 before taxes or other fees.

That range is published by the Spokane provider for two front windows. Before approving the work, ask whether “match” refers only to appearance or to a target finished VLT as well.

Scenario 5: Complex EV or luxury vehicle

Assume ceramic side-and-rear coverage plus separate windshield or panoramic-roof work:

Ceramic side-and-rear package: $600–$1,000
Windshield or roof work: $200–$400
Removal or preparation allowance: $0–$150

Arithmetic:

Low example: $600 + $200 + $0 = $800
High example: $1,000 + $400 + $150 = $1,550

Illustrative subtotal: approximately $800–$1,550.

This is a premium, extensive, or complex scenario—not an automatic surcharge for every EV or luxury badge. Detailed provider examples put luxury-vehicle ceramic packages at $600–$1,000 and some Tesla ceramic packages at $500–$1,200 or more, depending on model and roof coverage.

Build your own estimate

Use five lines:

Base film package: $____
Vehicle or complexity premium: $____
Old-film and adhesive removal: $____
Windshield, visor strip, sunroof, or panoramic roof: $____
Taxes, supplies, disposal, and other disclosed fees: $____

Estimated out-the-door total: $____

Do not fill in the first line until the shop defines the product and coverage. “Ceramic package” is incomplete if it omits the manufacturer, product line, and panes. Likewise, a higher quote is not necessarily better unless the shop can explain what the additional price buys.

A sensible budget leaves room for legitimate preparation or specialty-glass work without becoming open-ended. If a final removal charge requires inspection, ask how the estimate is calculated and what conditions could raise it.

DIY versus professional tinting: compare more than the kit price

Pre-cut DIY kits are commonly advertised at approximately $30–$100, while another commercial guide says DIY options may begin around $50. Those figures describe the material entry point, not the complete cost or likely result.

Cost or risk	DIY	Professional installation
Film	Kit or bulk-film price	Normally included in the quote
Tools	May require separate purchases	Supplied by installer
Cleaning and preparation	Owner’s responsibility	Usually part of installation; confirm
Cutting and alignment	Owner assumes difficulty and error risk	Included within quoted labor
Curved-glass shrinking	Can be technically demanding	Included when within scope
Time	Owner’s time	Shop turnaround time
Replacement material	Owner may need to repurchase	Depends on written defect policy
Finish	Depends on skill and working conditions	Depends on installer and process
Warranty	Kit terms may be limited	Product or workmanship coverage may apply
Rework	Owner handles it or hires a shop	Depends on written warranty terms

The $30–$100 range comes from the Spokane provider, while OC Tint Solutions states that kits may start around $50.

DIY offers the clearest potential savings when the owner already has suitable tools, a clean workspace, patience, and relevant skill. Simple, relatively flat side glass is generally more approachable than a compound-curved rear windshield.

Professional pricing pays for labor, preparation, handling, and installation experience in addition to the film. It may also include a product or workmanship warranty, but buyers should read the scope and exclusions rather than assuming every defect, future removal, or labor charge is covered.

Nor should buyers assume every professional installation will outperform every DIY job. The practical trade-off is lower initial material cost versus the owner’s time, workspace, skill, and risk of buying replacement film or paying for rework.

Published turnaround estimates also vary. OC Tint Solutions says most vehicles take 1.5–3 hours, while a Miami installer lists two to three hours for sedans and three to four hours for SUVs. Removal, specialty glass, preparation, and shop scheduling can extend those estimates. See the Miami installer’s stated turnaround ranges.

DIY may be reasonable if you:

Are patient and comfortable with precise film work
Have a clean, sheltered workspace
Accept the possibility of buying replacement film
Are beginning with relatively simple glass
Can verify that the product and finished VLT are lawful
Value saving labor costs more than saving time

Professional quotes become more attractive when the vehicle has:

A difficult curved rear windshield
Expensive premium film
Old adhesive or deteriorated tint
Panoramic or oversized glass
Frameless windows
Numerous small fixed panes
A schedule that leaves little room for rework

If you are undecided, compare the complete DIY cost—including tools and an allowance for replacement material—with several professional out-the-door quotes. The financial difference may look smaller once your time and the most difficult pane are included.

Choose a legal film and compare installer quotes fairly

VLT, or visible light transmission, is the percentage of visible light that passes through the glass-and-film system. A lower VLT means a darker finished result.

Film darkness and film technology are separate purchasing choices. Ceramic is not synonymous with dark, and dyed film is not necessarily the darkest option. Each technology may be offered in several VLT levels.

Tint requirements can vary by:

State or other jurisdiction
Window position
Passenger-car or multipurpose-vehicle classification
Windshield area
Reflectivity
Medical-exemption status
Other conditions defined by local law

Compliance may depend on the combined transmission of the factory glass and applied film, not merely the VLT printed on a film sample. The San Antonio provider specifically notes this combined-transmission issue, although its state-specific legal summary should not substitute for current official rules.

Because laws can change, verify current requirements through the relevant official state authority, DMV, highway-safety agency, inspection authority, or statute before authorizing installation. Window Tint Central likewise characterizes its material as general information and advises readers to verify changing tint limits with their DMV; that is publisher guidance, not legal advice. Read the publisher’s legal-information notice.

When requesting quotes, send every installer the same information:

Year, make, exact model, and body style
Film manufacturer and exact product line
Requested VLT for each window position
Front side windows
Rear side windows
Fixed quarter or cargo-area windows
Rear windshield
Windshield visor strip
Full windshield
Sunroof or panoramic roof
Existing-film and adhesive removal
Vehicle or glass-complexity charge
Taxes, supplies, disposal, and other disclosed fees
Written product-warranty coverage
Written workmanship-warranty coverage
Whether warranty labor is included
Whether the warranty transfers to another owner
Expected turnaround
Post-installation care instructions
Final out-the-door total

Obtain multiple itemized quotes and compare identical coverage. A headline price has little value when the film line, panes, removal work, warranty, and fees remain undefined.

When evaluating film, rely on product-specific documentation rather than generic category promises. When evaluating an installer, consider preparation practices, examples of comparable vehicles, written defect policies, warranty administration, communication, and the clarity of the quote.

Window Tint Central says its coverage draws on hands-on automotive and storefront tinting experience, identifies sources for quoted prices and specifications, and is neither sponsored nor influenced by paid manufacturer placement. Those are the publisher’s own disclosures—not independent validation of the regional price estimates and not a claim that the publisher performs installations or provides legal advice. See Window Tint Central’s experience and editorial disclosure.

A sensible starting budget remains about $150–$600 for professional tinting on an ordinary car, but that number becomes useful only after the package is defined. Compare out-the-door quotes for the same named product and panes, then account separately for removal, windshield or roof work, warranty differences, difficult glass, taxes, and disclosed fees.

The cheapest headline price is not necessarily the cheapest equivalent job. The most expensive ceramic package is not automatically the right choice, either. Select the product and installer according to your budget, parking and driving conditions, desired coverage, documented specifications, workmanship expectations, and current official tint requirements.

Frequently asked questions

How much does it cost to tint only the two front windows?

Budget approximately $80–$200 for the two front side windows. Some regional estimates for partial work extend to about $250, particularly where the job involves premium film, more difficult glass, or a higher-priced local market. See the regional front-window and partial-coverage estimates.

Confirm whether the quote includes existing-film removal, preparation, taxes, and any charge associated with the selected product. If the objective is to match rear factory privacy glass, verify the finished VLT rather than relying only on visual similarity.

How much extra does old-window-tint removal cost?

Old-film removal is commonly listed at about $50–$150 extra. The actual charge can depend on the number of affected panes, film condition, adhesive residue, access, and the care required around rear defroster lines.

Ask how the shop calculates removal and whether the amount can change after inspection. Brittle film, stubborn adhesive, or several affected panes may require more work than a simple removal.

Is ceramic tint worth the higher price?

It can be, but not for every driver. Ceramic may be easier to justify when a particular product’s documented specifications address the owner’s priorities, the vehicle is parked outside frequently, driving time is substantial, or the owner expects to keep the vehicle for years.

Carbon or another mid-tier film may be the better value when the vehicle is usually garaged, the ownership period is short, or the ceramic upgrade would displace more important spending. One California installer advertises full-car carbon starting at $380 and ceramic starting at $480, but requires a vehicle assessment for an exact quote—an example of why the upgrade must be evaluated locally. See the provider’s starting prices and qualification.

Does a full-car tint price include the windshield and panoramic roof?

Often it does not. A common package includes side windows and rear glass while excluding the front windshield, sunroof, panoramic roof, old-tint removal, taxes, and other charges.

Ask for a pane-by-pane coverage list. As planning figures, full-windshield film is often quoted at about $100–$300 where lawful, while panoramic-roof work commonly falls around $150–$400, depending on size and complexity.

Does darker window tint cost more?

Not necessarily. Darkness is expressed through VLT, while dyed, carbon, and ceramic describe film categories or technologies. Each category may be available in several shades.

A shop may charge more for an uncommon product, custom design, or specialty shade, but a darker film is not automatically a more expensive technology. Compare the manufacturer, exact product line, VLT, coverage, and written warranty—not darkness alone.
