The darkest tint commonly available is 5 percent VLT, often called “limo tint.” It lets through 5 percent of visible light. From outside in daylight, you cannot see in. From inside at night with the dome light on, you can be seen perfectly. That trade-off matters before you pick it.
In Texas, you can install 5 percent on the rear side windows and the back glass with no restriction. You cannot install it on the front side windows or anywhere on the windshield below the AS-1 line. The law is non-negotiable on the front.
If you came here looking for the maximum-darkness option, here is what you actually get with each level, what the law allows, and what we install on most customer vehicles.
How tint darkness is measured
VLT stands for Visible Light Transmission. The percentage is the amount of visible light that passes through the window after the film is installed. Lower percentage means darker.
5 percent: nearly opaque from outside during the day. The darkest standard option.
15 percent: very dark. You can see large shapes inside but no detail.
20 percent: dark. Some interior visibility from outside up close.
25 percent: medium-dark. The legal floor for front side windows in Texas.
35 percent: medium. Common factory privacy tint level.
50 percent and lighter: light tint. Mostly for heat and UV, light privacy.
The number on the box is the film alone. Once the film is installed over factory glass, the actual measured VLT is lower than the film number. A 20 percent film over standard 80 percent factory glass meters at about 16 percent.
What the Texas tint law actually allows
Front side windows: 25 percent VLT minimum after factory glass. You cannot legally install darker on the driver and front passenger windows.
Windshield: only the top 5 inches can be tinted. Any darkness allowed in that strip. The rest of the windshield must be clear.
Rear side windows: any darkness allowed.
Back glass: any darkness allowed.
Reflectivity: front side windows capped at 25 percent reflectivity.
Medical exemption: available with documented medical need.
This means the darkest legal setup on a typical sedan or SUV is:
Top 5 inches of windshield: 5 percent or whatever you want.
Front sides: 25 percent (the legal limit).
Rear sides: 5 percent.
Back glass: 5 percent.
That setup is what most customers asking for “the darkest” end up with.
Going darker on the front: what happens
Some shops will install darker than 25 percent on the front. We will not. Here is why.
Texas law enforcement carries tint meters. If you get pulled over and the officer checks the front sides, illegal tint is a fix-it ticket. You then have to remove the film and replace it with legal film, plus pay the fine. The cost of doing it twice is more than just doing it right the first time.
Beyond the legal problem, dark front tint hurts your nighttime visibility. The driver loses meaningful contrast in low-light driving. We see this with people who come back wanting their tint replaced because they cannot see well at night.
If you have a medical condition that justifies darker, the Texas medical exemption process exists for that. Get the paperwork from your physician or optometrist, keep it in the glove box, and we will install whatever VLT your exemption allows.
What 5 percent looks like on the road
In direct sunlight, 5 percent on rear side windows looks black. Standing next to a car in a parking lot, you cannot see passengers in the back seat or anything sitting on the rear bench.
At night, with interior lights off, 5 percent still hides almost everything from outside. With a dome light or a phone screen on, the inside of the cabin is visible from outside.
Driving at night with 5 percent on the back: you have less visibility through the rear glass than with lighter tint. Most people compensate by relying more on side mirrors. If you tow a trailer, run a backup camera, or do a lot of city driving where rear visibility matters, consider 15 or 20 percent on the back instead of 5.
Carbon, ceramic, and dyed film at the dark end
The darkness itself is just the VLT. The technology of the film matters too, especially when you are running dark tint that you want to last.
Ceramic at 5 percent: most expensive of the three. Best heat rejection at any darkness level. We install Llumar IRX and 3M Crystalline. Holds colour well over years in the Texas sun.
Carbon at 5 percent: middle tier on price and heat performance. We install Suntek as our carbon option. Lasts longer than dyed film, blocks less heat than ceramic.
Dyed at 5 percent: the cheapest option, but the dye fades and shifts purple under UV exposure within a couple of years. We do not install dyed film.
For dark tint specifically, ceramic is worth the upgrade because dark film absorbs more heat than light film, and you want the film type that handles that heat best.
Pricing for full vehicle dark tint
Full vehicle ceramic tint at our shop is $450 to $700, with the upper end for larger SUVs and trucks. Carbon is $250 to $375. Both prices include the front sides at the legal limit and the back as dark as you want.
Install time is 2 to 3 hours for most vehicles. Wait three days before washing the car after pickup, and two weeks before any high pressure washing.
If you want to add headlight tint or smoked taillights, those are separate. Headlight tint runs $100 to $200 per pair.
What we recommend for darkest legal setup
For somebody who wants maximum darkness on a daily driver, our default recommendation is:
Front sides: 25 percent ceramic (Llumar IRX or 3M Crystalline).
Rear sides and back glass: 5 percent ceramic.
Top 5 inches of windshield: 20 percent ceramic strip.
That setup is fully legal in Texas, blocks the most heat we can legally block on the fronts, and gives you full privacy on the back. It looks balanced from outside and reads clean on a tint meter.
For somebody who wants dark but not maximum dark, 20 percent on the back instead of 5 percent gives more rear visibility while still hiding the cabin during the day.
When you should not go darkest
Backing into tight spaces regularly: 5 percent on the back makes night reverse harder unless you have a good camera.
Driving older vehicles without backup cameras: skip the darkest level on the rear for safety.
Picking up kids regularly: parents often want 20 to 25 percent on the back instead of 5 so they can see into the back seat through the side windows easily.
Reselling soon: very dark tint can narrow the buyer pool for some vehicles. Lighter tint is more universal.
If any of those apply to you, going one or two steps lighter than the maximum is the smart call.
Get tint set to your situation
We tint cars across Wylie, Plano, Frisco, Allen, Garland, and Rockwall. Every install gets metered for VLT before the car leaves so you know the numbers are correct and legal.
Tell us the use case when you call. Daily commuter wanting privacy, weekend driver wanting heat rejection, parent wanting back seat visibility. The right tint percentage depends on what you actually do with the car, not just the law on paper.
The darkest tint is not always the best tint. The right tint is the one that fits your driving and your vehicle.
