Carbide Series OverviewThe Carbide Series 2.0 7440/7443 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)

These lights are super bright and light up the road a bit.

can't seem to get anything out of customer service, no return emails, no calls

Charles VanEvery

The lights seem to be good quality but I can't try them because I ordered the wrong bulb for my f150, that's my fault not HR. My problem is I've sent emails about returning the bulbs and getting the correct ones sent out to me at my cost but I've gotten nothing in response after three emails. I tried to call the phone number several times and it seems to be disconnected, it just goes to a Verizon recording. The warranty isn't going to mean much if they won't respond when something comes up.
I will be taking my business elsewhere, where I can get a response when problems arise.

Not having to put resistors in line is a good feeling

Finally, LED turn signals without resistors

Marshall Chung

I don't usually leave review for product that I've purchased. However, this product works so well, so easy to install, and addressed the biggest issue I have with LED bulbs when used as turn signal is hyper flashing. Since my vehicle (2017 Toyota Highlander) was not listed as one that this bulb works, I was very skeptical about them. Also, I've read negative reviews of a different brand of LED bulbs that also promised to address the hyper flashing issue but suffer from overheating problem, which then causes the LED bulb to hyper flash. However, I decided to take a chance and try these anyway. I am glad that I did. I purchased the single color amber version and they work great! The color is rich orange color and they are super bright! If I have to think of anything negative to say about these bulb, I would say these are a little too bright. When the turn signal is on, I could see it light up the cabin of the car in front of me. Other than that, I can't think of any other negative thing of these. Awesome product!

Wouldn't work in my 2019 Jeep Wrangler JL

James Partin

The bulbs were nice & bright but the turn signal wouldn't work. I'm giving these a good review because of the customer service at Headlight Revolution. They made it easy to swap these out for bulbs & resistors that did work.

These LEDS are awesome. Easy

William co oren Alvarez Jr.

These LEDS are awesome. Easy to install, very bright. I like the fact that it stays white and blinks amber. Factory it's just amber. The color is on point.

Front turn signals

Select Prefix/Title

I purchased the front turn signals for a '19 Ram Big Horn. At first I was impressed with the brightness. However, after driving in the hot weather (90's), these lights started to hyper flash and I got the message to replace them. I guess you can't use them when they warm up! Another time they malfunctioned is when I was in some traffic turning for about 5 minutes. These need to be taken off the market and redesigned! What a joke!

excellent, they work and look great!

Christopher Hwang

Got the switchback version, the bright white is a nice addition to the look of the lights/facia but they are not super bright - I would not expect them to contribute to usable light but that's not the purpose, they look really good.
The yellow turn lights are super bright though! They are truly plug and play, no issues at all. As advertised and did not disappoint.

Great product

Michael Galanto

For a switch back the Amber is great but the white light could be brighter.
