Carbide Series OverviewThe Carbide Series 2.0 3156/3157 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)

Works with 2015 Ford Super Duty

by -

At the time of purchase, HR couldn't confirm if they would work with a 2015 Ford Super Duty but I bought them anyways and they work without any hyperflash. They look great on the truck.


Super Bright, No Resistors, but Heavy

by -

So these LEDs are great. . . super bright and no resistors; however, because they're "top" heavy, they always seen to work their way loose on the socket. . . causing them to not work until I reseat them. . . I have yet to solve this problem, but I plan to manually shim the LED's so that they fit SOLIDLY into the socket.


Super bright direct fit bulbs, switchback feature 100% worth it


I installed these lights (non-CK wiring) on my 2012 F250 Super Duty in the factory Ford headlight housings with some upgraded LED headlight bulbs as well. Night and day difference and the switchback bulbs (white running light with amber turn signal) really modernize the look of the factory housings. The bulbs worked in the truck perfectly, plugged right in with no super-blinking or error codes (since the application is non-CK I did make sure and check polarity, they didn't light up in one direction so I reversed them and they worked great after that).

100% recommended, amazing product!




Switchback daytime running lights, 2015 Tacoma.
First make sure to order the CK version for a Toyota.
1st position, DRL, they are bright AMBER, I thought they would be white.
2nd position, parking lights, they are COMBINED WHITE AND AMBER, (look nice).
3rd position, headlights, they are WHITE. They make the stock headlights look kind of yellow.
Turn signals/flashers are BRIGHT AMBER.
The LED's are very bright and I like them a lot. I think it's the Toyota wiring that makes them behave as they do.
I may want to change out the headlight bulbs for a brighter white, but that's a bit more complicated and a lot more expensive.


17 Toyota Tundra


Ordered these for my front turn signals and they worked out great. I got the CK amber and they look so much better than OEM.


05 Cadillac STS Yes And No


I installed in my cadillac. At first glance they are blindingly bright when you signal. My issue comes in when the parking lights are on and you flip the turn signal on. It hyper flashes outside the car for the first 1-2 seconds before it catches and flashes normal and it does this every time. They work normal mostly when the parking lights are off (headlights on) and you flip a turn signal. Then it will hyper flash for that couple of seconds 1 time per side before it acts normal. It remains normal every time after that 1 initial hyper flash for that key cycle. The next time you start the car it does it again. And if the headlights turn off (running/parkingblights on) then it goes back to hyperflashing every time you activate your turn signal.
I installed them in my 05 silverado to see what happens. They work as intended no issues in my truck.

Good bulbs but too long


Works as advertised, super bright, no CANbus fault. But too long to work as front turn signal bulb in e39 BMW, will be hitting the lens.
