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)

Brett Ingram

Had a problem but when I talked to them the bent over backwards to help me. I will do business again and again. This is how customer service should be. Thanks Headlight Revolution and yes I love the bulbs work well and are super bright.

Great bulbs

Nick Lampson

These bulbs are fantastic! I ordered them in the switchback function and they work perfectly just like the video. The install was super easy as well! Initially we had a little mix up with shipping but Caleb in customer service worked hard to figure out the problem and made sure I received the proper bulbs the next day! I upgraded all my lights through headlight revolution, they are fantastic!!

2017 Chevy Impala

I bought two sets of these, a white pair and switchbacks. On the switchback, the white color is definitely not as bright but when flashing, the amber is very bright (to the point of nearly illuminating every object in front of my car). When flashing, the white light doesn't turn off, so it just switches between white and amber. These worked for me without needing to splice in resistors. The white bulbs I bought for my reverse light and they didn't disappoint either. Very bright at night which helps me see while backing up and when leaving my car. I bought these bulbs for my reverse light rather then something else again for its lack of need for a resistor as my reverse light circuit is used to activate the auto dimming mirror and to power down the BCM (if I use any other bulb they remain dimly lit on, even when the car is off). Highly recommended unless you don't like the switchback's blink style.

So far, so good!

Joseph Housenick

These bulbs are very bright and seem to work well. I installed them about 2 weeks ago, and so far, no hyperflash or bulb out display in dash. They seem solid and well made. However, these are very expensive $78 and took about 2 weeks to ship...not 2 days.

Bright as hell

Jose Diaz

These LED bulbs were used on a 2014 Lexus is350. As for turn signal it works phenomenal. As for emergency flashers they go out of sync unless you use the resistor to avoid hyper flash. No regrets waiting the the front ones.

Couldn't be happier

Stephen Van Lowe

To start off, These work perfect in a 2016 Silverado 1500 despite not being on the confirmed list. All I can say, is holy cow these sucker's are bright. Install was a pretty easy. A little more difficult on the passenger side as the air cleaner and some kind of cover was in the way. The only issue I had was the item was backordered and I was not aware of it until I called Headlight Revolution. I did have to call multiple times because I was told they would ship on a certain date but wouldn't. Took over a month to finally get them, but glad I waited and didnt ask for a refund.
