The Carbide Series LED replacement bulbs from GTR Lighting: were originally designed to be the brightest option in the world and today with the version 2.0 they're even brighter! Because these bulbs are the brightest option available today you will experience greater safety from a brighter light, better performance through built-in CANBUS integration, and better style with the beautiful colors created by the custom built LED chips!

Not just the brightest: but also the easiest! In the past you had to wire in resistors to your turn signal bulb circuits in order to trick the computer into thinking that your LED bulbs were the same thing as your old dim bulbs. Not anymore! The new Carbide Series 2.0 bulbs have a built-in CANBUS-integration circuit that works with 95% of all cars, trucks, and motorcycles on the road today! Gone are the days of wiring in resistors, or replacing flasher modules. These new LED bulbs are truly plug and play, and one of the brightest and most reliable options around.

ITCS - Intelligent Temperature Control System: The Carbide Series 2.0 CANBUS LED bulbs have a unique physical design as well as a temperature controlled thermister circuit to protect the bulbs from overheating. The aluminum case of the bulbs is larger than others in order to accommodate the extra heat given off by these bulbs. There are strategically placed vents and heat sink fins at the top of every bulb to maximize passive cooling.

These bulbs: are polarity specific. If they do not turn on, please try flipping it around in the socket and try again. If the bulbs stop working it means they got too hot and the protection circuit shut down. Please try to cool them down for 2 minutes and try again to troubleshoot the problem. These bulbs have a 1-year No Questions Asked warranty.

Constant Current Driver: The Carbide Series 2.0 LED bulbs from GTR Lighting are built using a state of the art Constant Current Driver inside the bulb with built-in CANBUS function for most monitoring systems. This allows them to be more reliable when used on vehicles that have voltage fluctuations due to electrical system design or fault. A constant current driver is a device that takes any incoming voltage and smooths it out, regulates it, so a steady stream of voltage/current reaches the LED. This helps the LED bulb last longer than bulbs that don't have this device built in. 2,400 raw lumen light output per pair of bulbs making these bulbs the brightest option in the world! Features maximum CANBUS support - simulation of the full load 24W bulbs commonly found in turn signals. No errors in cars or trucks 95% of the time.

Great bulb but does have an issue


These are great bulbs, but the switchback function will not work in a Morimoto XB Hybrid headlight for a 2019+ Ram 1500. The turn signal bulb in this particular headlight does not function as a parking light like the stock halogens. It’s for this reason, a switchback bulb will not turn on unless the turn signals are activated. The amber portion of the bulb still works as intended, the white leds, however, do not.


Great Product!

Gives a sharp look to my Ram 1500. Install was easy. I thought I had a defective LED as it did not light up on the driver side. Swapped it out with the passenger side and they worked correctly, but driver side was still having issues not lighting up. I then swapped the housing and now both lights up and works great! I just have to work on replacing the low beams and fogs lights to match.


Best Ever

The resistor less switchbacks signal lights are the best I've ever seen and I have seen another brand that looks similar but GTRs are the best and the brightest very happy thanks guys


Great upgrade!

These switchback blinkers gave my truck a new cleaner look that I actually like BETTER than the factory LED's that my Bighorn did not come with. I ended up changing all the halogens to LED(Low Beams High Beams and Fogs) and I'm pleased with the appearance.
