So I was on a trip this weekend when I discovered my rear lights were out. But the brake lights worked. I pulled the fuse to the rear lights, reset it, and everything worked fine. I then adjusted a mirror down, as I was on a late night 400 mile journey, and all was fine. Until I stopped for gas. It went out again. I reset it again, and it worked again. Until I stopped for gas again. This time I pulled the fuse for the ecu. Everything has worked fine since.
