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.

3156/3157: GTR LIGHTING CARBIDE 2.0 (RESISTOR-FREE)
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.
Great lights gonna be ordering for my other trucks and my wife said IÃÃ´ll be ordering for her car to great lights
Did not work
I got the switchback model of this light. Frost off they did not switch at all amber and whit lit up at same time. Then only after 3 days the amber on bulb stopped working and only the white worked.
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.
Amazing LED Lights
Danny A Young
I was initially a little reluctant to buy these lights as it IS quite an investment however, it so far is money well spent! I just installed my GTR Ultra 2 H11 headlights & I'm very happy! They are bright yet not 1 person put their brights on while I approached them! I've had the GTR Carbide Canbus 3157's & Reverse Lights for a few months now with no issues! Technical Support is SUPERB! My only hope is that they last a lifetime & Technical Support never waivers when an issue comes to light!
Hyerflash issues in the dash.
I purchased the red version of these for the rear tail/turn signals for my 2017 F150 XLT as an upgrade from the stock halogen bulbs. I purchased these because the description said they were CANBUS friendly and there would not be a hyperflash issue. The lights themselves are very bright for both the tail light and turn signal modes, but they definitely leave a bit of a dull area right in the middle of the housing. When looking at the entire light assembly from behind the truck, they put a lot of light towards the top and bottom of the reflector area, making it appear that there is 2 horizontal light bands, but the middle of the tail/brake light area lacks brightness. The standard bulb does not do this as the light output is more uniform throughout the entire area. When compared to the stock bulbs, there is definitely a huge light output difference, and the red is much more pronounced. Side by side, these LEDs make the stock bulbs look like a light red to almost deep orange color. I definitely have no complaints on the color or the intensity. What I do not like is the hyperflash in the dash. The bulbs themselves flash at the normal rate on the back of the truck, however, the dash turn signal indicator hyperflashes. I do not want to add resisters to the wiring, so I will attempt the ForSCAN programming option to see if this fixes the hyperflash. 5/5 for brightness, quality, and color, but 4/5 due to the hyperflash issue without other modifications (resisters or ForSCAN programming), meaning these are not truly 100% plug and play.
Installed as Tail Lights and Front Turn Signals, Required Resistors
I purchased a set of the switchbacks for my front turn signals and two sets of the white bulbs for my tail lights/rear turn signals in a 2011 F-150. I bought these because I was under the impression that the CANBUS technology meant I wouldn't need resistors.
Switchbacks: Installed very easily and DID NOT need resistors (in my particular truck) to flash at normal speed. The white light is a little dimmer than I expected, but it does complement the color and output intensity of the SV3's I have for headlights. The amber for the turn signal is RIDICULOUSLY bright. It lights up the street signs two city blocks ahead of me.
White: Installed very easily and DID required resistors (in my particular truck) to flash at normal speed for my rear turn signals. The brightness behind the red reflectors is better than the stock/incandescent lights I had previously, but, again, these LEDs are a little dimmer than expected when looking at them through the lens. After telling HR customer support about the hyper flash issues, they quickly sent the appropriate resistors to me at no charge. The video found on the HR YouTube channel was clear and helpful.
Overall, these lights were worth the money, even though they were a little dimmer than expected.
