I am having a little issue with my 3rd brake light, I think it may be a fuse because there is no visable issue with the wires. Does anyone know which fuse the 3rd brake light is wired into? Any thoughts on what else it could be would be apprecaited. Thank you.

 

It is wired to the same fuse (Stop/Haz fuse)as the regular brake light. If it was bad then you wouldn't have any brake lights. The culprit that you might want to look at is the brake switch. It has two independently operating switches inside it and one could go bad without effecting the other

 

Thanks Trickster, what would you recommend to test this? Or should I just take a shot and buy a new one? Oh, and by Brake switch do you mean the switch behind the brake pedal the senses the pressure on the pad?
