Tundra Turn Signal Upgrade: If your Tundra has the OEM Toyota LED headlights and you want a better turn signal, this is the BEST option possible. This kit comes with everything you need to upgrade your stock headlights to the newest, brightest, and best LED turn signal option in the world. The GTR Lighting Ultra i-LED bulbs look cool, are totally plug and play, require no custom wiring or splicing, and are insanely bright! These bulbs will improve your safety by having a bright amber light when turning, and improve your style by removing that ugly old-style amber bulb from glowing in your headlights. Follow the instructions in the video to see how easy the install can be!

New Benchmark: When it comes to high performance LED Bulbs; the numbers game is simply an excuse for a lack of engineering, and GTR Lighting isn't here to play that game. The i-LED bulbs from GTR Lighting are here to win, and when you see them next to the aging competition, you won't worry much about the numbers.

Ultra Optics:The optical system on the i-LED bulbs is highly effective at maximizing output. It projects a considerable amount output forward to provide a vivid taste of intensity up close, but more importantly it reflects more than half of the output backwards onto the surrounding reflector of your head/tail light --which is what drives intensity when viewed from a distance.

Resistor Free: Make no mistake, these are still extremely powerful bulbs. The i-LED consumes nearly the same amount of power as the original incandescent/halogen bulb, which conveniently makes them resistor-free in many applications too. We do however recommend the optional plug-n-play modules for the most reliable hyperflash-free fitment into any position that acts as a blinker, regardless of application.

Applications: The GTR Ultra i-LED is available in a pure White, Red, PC Amber, and White/Amber Switchback. Their universal collar fits any headlight or taillight housing, making them the perfect solution for those who are unwilling to compromise on intensity from their turn, brake, tail and daytime running lights.

i-Driver: The intelligent LED Drivers have been tuned to maximize intensity without compromising in the reliability department. The high-output mode is over-driven for < 2 sec to maximize initial intensity, before ramping down to a more conservative drive rate that the system can handle long term.

Style, Even During the Daytime: Don't forget about the fact that everybody still see whats inside of your headlights during the daytime, even when they're un-lit. The GTR i-LED looks superior compared to everything else out there thanks to the fact that you cannot visibly see the LED chips directly. All you see is the business end of the bulb, with its mirror perfect, crystal clear optics protruding out of the anodized aluminum base. Perfection.
