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)

Vivid upgrade


Purchased the 7443 amber (non CK) for 2016.5 Mazda CX-5 Touring and I have to admit I was skeptical. They worked right out of the package with NO hyperflashing. I also purchased the 1157 switchbacks but I am having an issue with those. working on a solution

performance is the upstanding. be thorough on the install

i bought these in switchback version as blinkers for my moriimoto hybrid headlights. the work as described and match the color temp of the headlights. just do one thing: make sure you test these bulbs. they only work one way. they can be installed flipped the wrong way and won't work which will temporarily freak you out. Both sides of the installed base have the same offset contacts on both sides which will lead you to believe that the bulbs can be installed either way. have your hazards on and install both until they light up.

The Best Available

I bought both the Amber and Red for my 2013 Toyota 4runner SR5. Confirmed Standard sockets with my shop. Beautiful color and super bright. No hyper flash on rear turns w/o resistors. Reds get hot but not hot enough to warrant resistors.

Hyper flash Don't buy.

I bought switchback white/ amber bulbs for the front and 4 red for the rear. I could have spent under $20 a pair on Amazon but chose these for my new 2020 duramax because they claimed to have no hyper flash because of built in resistors. I called to confirm this before purchasing and was even emailed with the bulbs recommended for my truck. Nearly $300 later and they don't work as promised.

These lights are the real deal. Now my 2020 Chevy HD LTZ is all LED upfront as it should have been from the factory
