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.

Not compatible with 2015-2018 Ford Edge


The website did not list the switchbacks as an option for the 2015-2018 Ford Edge, and with good reason. I chatted to one of the technical support guys who thought it would work with the anti-hyperflash harness, so I went ahead and ordered the switchbacks. Delivery was fast, they were packaged well, the quality of finishing was extremely high, and they were easy to put together and install. Unfortunately, the website was correct and they were not compatible. I reluctantly had to return them. Headlight Revolution's customer service department was very good about the return and assisted me in selecting another product which was recommended on the website as being compatible with my car. These did not function in my car, so it seems a little unfair to give it a star-rating, but picking a star rating is mandatory, so 4 stars.
