This popular Tesla Model S aftermarket accessory, the Lighted T, is a subtle, yet unique way for any Model S owner to add a bit of extra flair at the rear of the vehicle. This lighting modification, custom designed exclusively for the Tesla Model S, provides a lighted halo effect around the Tesla T logo area. The halo is tied to brake lighting, causing it to illuminate more intensely when the brakes lights illuminate. The Lighted T definitely adds a unique accent to the back of your model S, but does it in a tasteful and understated manner.

Customer Testimonials

"This aftermarket product from EVANNEX is for those certain drivers who want it to be crystal clear that they are the proud owner of a Tesla." Glen Gaslin, CNET "Insane mods for your Tesla"

"Once I bought my Tesla Model S, I knew I wanted to design and create the car on my own terms. I think the car is beautiful as is, but believe subtle changes could make a drastic difference in terms of its appearance. The Lighted T gives the vehicle an appeal that subtly stands out amongst its peers. Cutting edge, forward-thinking, ahead of its time, and it beautifully presents a paradigm shift on the automobile world by bringing the future of design to the present--all things in line with the brand of Tesla as a whole." - Dr. Shey Olaoshebikan, Los Angeles, CA

"I had been eyeing the illuminated front and rear Tesla logo from EVANNEX for a while... I had the installation done by a local garage in Basel ( and Semir did a great job. Here are pictures of the results." -





Is the installation of the Lighted T a DIY (Do It Yourself) project?

No, it is imperative that product installation is left to a professional installer. Therefore, professional installation is required.

Where can I find a professional installer?

There are many competent aftermarket installation locations (they often specialize in car audio installs)  in your locale. It may be helpful to locate a professional installer who has had experience with the Tesla Model S and comes recommended by others. We've created extensive installation materials (including a detailed installation video, see 'Installation' tab) in order to assist a professional installer with guidance as he/she installs Lighted T.

How long will it take a professional to install the Lighted T?

Installation is a job for a professional installer. However, for a professional, it’s a relatively straightforward task (as we've provided both written and video instructions) that can be completed in a relatively short time frame. The front T takes about 60-90 minutes, the rear about two hours. However, we advise that you ask your professional installer to provide an estimate as timeframe and pricing may vary from installer to installer.

How much should professional installation cost?

We suggest you get an upfront quote from your professional installer, but, typically prices can range from $60/hr. - $150/hr. depending on your location. As we noted earlier, some professional installers estimate that the rear Lighted T requires about two hours of labor, sometimes this depends if the installers have significant experience working on Teslas.

What kind of modifications to my car does installation of the Lighted Ts require?

Very few. Each Lighted T consists of an injection molded plastic shell that is positioned under the rear chrome Ts with double sided tape. The factory chrome Ts are temporarily removed and a very small hole is drilled in the trunk hatch for the wiring, but the holes are positioned so they are not visible. After the Lighted Ts are positioned on trunk  hatch the chrome Ts are reattached on top of them.

Will the Lighted Ts affect the functioning of my car’s electrical system?

No. The Ts are powered by the car’s 12V system and connections are made to existing 12V lines and ground.

How much electrical power do the Ts require when they are lighted? When they are off?

The Lighted Ts draw very little power, only hundreds of milliamps. When they are off they consume no power.

Will the Ts run down my 12V battery?

No. The current draw of the Ts is so low that it would take (estimated) about a month to drain the 12V battery if they were turned on and car was not plugged in or driven.

How will operation of the Ts be affected by wet and inclement weather?

Not a bit. The Ts are completely waterproof and not affected by extreme cold or heat.

Will the Lighted T’s violate traffic and/or other vehicle laws in my state?

No. The colors and position of the Lighted T's meets state safety laws regarding both the front and rear light. Consistent with these laws, the front T lights white the rear T lights red.

Will the Lighted Ts leak toxic or other foreign material that might damage my car?

None of the chemical or physical properties of the Lighted T can damage the car or its painted surfaces. Both are made of inert plastic and waterproofed with epoxy in a hardened state.

How will the Lighted Ts affect service on my car?

Not at all. They will not interfere with routine service protocols.

What happens if my Lighted T doesn’t work or seems to have something wrong with it?

Hundreds and hundreds of Lighted Ts have been sold, and the failure rate for these devices is extremely low, but if your Lighted T fails or functions improperly immediately after your professional installer installs the product, please have your professional installer contact us at EVANNEX for guidance/advice. If that doesn’t resolve the problem a replacement can be provided free-of-charge.

How does the rear Lighted T work with the tail lights and brakes?

The rear T is installed so it turns on with the tail lights and brightens when the brakes are applied. During daylight, when the tail lights are off, the T is off until the brakes are applied. It lights up with the brake lights.

Does installation require permanent changes to my car that can’t be reversed?

No. The lighted Ts can be removed at any time, the wiring disconnected and removed, and the OEM chrome T's placed back in their original positions, restoring the car to its original condition.

Can the Lighted T be vandalized or stolen off my car?

Nothing is vandal proof, but the Lighted Ts are very difficult to remove without knowledge of how they are attached.

If they get wet will the Lighted Ts affect my electrical system or create problems such as electrical shorts?

No. Aside from being protected by the car’s fuse system the Lighted Ts are completely waterproof.

What if my installer has questions that I can’t answer?

We have provided written and video installation instructions that can help guide a professional in the installation of the Lighted T. Please have your professional installer reference the "Installation" tab on this page (prior to his infall). Note: written instructions are also provided in the package you'll receive post-order. If there are other questions, please contact us.

What provides the light for the Lighted Ts?

The Lighted Ts are lit by miniature LEDS arrayed on a T shaped printed circuit board that is embedded in the injection molded plastic shell.

When I buy the rear Lighted T is everything needed for installation included – wiring, connectors, etc?

Yes, all parts required for installation are included – wire, fuses, connectors, remote, custom cut double sided tape, even a small tube of silicone sealant, etc (see "Installation" tab). Every installation may vary slightly and as a consequence your installer might use an additional connector or some other item not in the kit. Professional installers typically acquire these from readily available sources. We do not provide the tools needs for the installation.

What tools are required for installation?

Very few (and no special) tools are needed: professional installers will have everything necessary: wire cutters, voltmeter, wire strippers, electrical tape, etc.

What is the shipping time frame for this product?

The EVANNEX Lighted 'T' usually ships within 24 business hours of receipt of order. Delivery time depends on your location relative to South Florida and is typically within three (3) days for the continental U.S.

Do you ship this item internationally?

Yes. We do ship the Lighted T's internationally.
