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.

Brightest Switchbacks on the market right now!

by -

I was impressed at the overall performance of these bulbs. They are briiiight when you activate your turn signals. I see them illuminating the reflective street signs at night dramatically which tells me the lumen output is notably better than my previous switchbacks. I had the jdm astar 3030 type switchbacks which are good but these really are that much brighter and nicer. These are no joke when it comes to their performance.


Should be called reverse search& rescue light


I installed these on a 2016 Ford Explorer. The stock reverse lights are horrible! Backup camera was useless at night in poorly lit areas, even using my mirrors.
I decided to go to the local auto store and get the super bright led replacement lights they had for $20+.... My opinion, save your money.. another useless set of lights. I decided to bite the bullet on these lights... Even though they are pricy.. but, wow! So worth it.. I can actually see at night backing up! In pitch black I can use my reverse camera! Looks like a set of year facing headlights!
Fantastic product! And easy to install.
