Bright Lighting: Combining super bright LED chips and an integrated heat sink allows these Festoon bulbs from GTR Lighting to help you see better than ever. They're built tough and are packed with the technology to handle any workload you have for them for years.

Design: To begin with, these Festoon bulbs are created with the LED Chips focused in the same direction so you can get focused lighting where you want it. In addition, the heat sink on the opposite side keeps them cool and running longer than lesser bulbs. Finally, they're built with Canbus integration so if your vehicle tends towards bulb out warnings when you use LEDs, this solves that problem without additional wiring or resistors.

Great Product, Excellent Customer Service

The original order ended up being the wrong color, RedĶ I ordered White. Contacted customer service, was notified IÄôd be send a replacement, no charge. And in a few days not only did they replace it, they sent me two bulbs. Plus a sheet of decals, which I have placed under the hood of my truck, I installed their LED for my underhood light. This way if someone asked where I got my LEDs at, I remember because I have the decal.


Is a very nice bulb.
