2015 1500 3.6

So I have had issues with this forever. I am losing lights in my LED taillight, And it is sending a code saying my right turn signal is out. My truck is a 2015 so it was more common at the time to use halogen taillights and not LED. I believe it was a custom truck because my headlights are halogen. But for that specific range of years, nobody makes an aftermarket tail light for the LED it is almost all not compatible with anything but Halogen.

I believe it was a custom truck because my headlights are halogen.

All the Gen4 trucks came with halogen headlights, there was Dual and Quad reflector type headlights and also a Projector headlight which you truck probably has if it came with the OEM LED taillights.There was no factory LED headlight option for the Gen4 (DS body) trucks.
