T have a short-out in the left bullet of my tail light. It is not the bulb, but i know it is an electrical problem within the wiring of the light. But, there is no way to get to the actual wiring without breaking the weld of the light or removing the bumper. The light works and is very dim. but when i step on the brake the light goes out Please help!! Im stuck, i dont know what to do. any help is appreciated!
