Product Details


Carbide Series OverviewThe Carbide Series 2.0 921/T15 from GTR Lighting is a remarkable bump in performance from what was already a good light in version 1.0. These LED Lights are focused on one thing, getting the most light onto your target as physics will allow for. Here at Headlight Revolution we personally love the visual appeal of the lights even when they’re off. GTR poured some real effort into designing an attractive package and it shows. What might amaze you is how much technology is packed inside though.


CANbus Compatible - Canbus vehicles can wreck a brilliant lighting upgrade in no time. GTR doesn’t want its customers experiencing that pain and neither do we. That’s why we love that the Carbide Series 2.0 has Canbus integration built-in. No more resistors, no more having to hack your wiring to ensure you avoid “bulb-out” warnings, no more flicker, and no more hyper flash. It’s all a thing of the past with the Carbide 2.0.

Redundencey: The Carbide Series 2.0 features something called the Intelligent Temperature Control System or ITCS. It features layers of design that keep this bulb cool on the hottest of days. First, the aluminum casting itself evacuates heat at a rapid pace. Add to it internal heat sink fins that further cool the light. Finally, if for some reason the light should experience unexpectedly high temperatures a thermistor circuit is constantly monitoring in case the power needs to be reduced. There’s no way around it, GTR wants this to be the last set of bulbs you ever buy.

What's Included:
Two CANBUS Friendly LED Bulb Replacements (Fixes rapid flash, hyper flash and bulb out errors)
