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)

great output....but...


I installed these and the little buggers looked amazing, they are super bright great amber color. As soon as I hit a bump or 2 on the road on my test drive one popped loose and ended up sitting loose inside my headlight. I thought it was my mistake at first so I disassembled my entire front end to remove the headlight and fight to get it to fall back out. Reinstalled and thought everything was fine. Next drive down he road it happened again on both lights. I wasn't riding down a rough road im just talking about little bumps.

Stock halogen bulbs stay clipped in with no issue. I had to go through the entire front end disassembly a 3rd time and this time I tacked the bulbs in place with 2 small dots of CA glue. Going on a week with no issues and they look great. The hassle of disassembling my front end 3 times is why its getting a low rating.

The stock halogens have an indentation that holds the bulb in the socket the canbus were completely flat and would not click into the socket.

Very Bright, but seem off in color


These worked great in my wife's 2018 Equinox, no hyper flash or bulb out warning.

Two things I'm not found of:
1. Amber color. These are VERY bright, hands down. The amber is a much darker hue than an incandescent, or even other led bulbs I've used in the past. Compared to the OEM amber in the headlights and mirror signals it looks out of place.
2. Fitment in the socket seemed loose. I always use a little dielectric grease on all electrical connections I break apart from factory, road salt can be nasty otherwise and cause corrosion, and the bulbs felt like they didn't want to stay seated well. Ended up wiping 99% of it off and just going with the little that remained after, otherwise the leds would pop out of the socket when locking the holder into the housing. That being said they haven't come out now after 2 weeks.
