i don't know what the problem is. the rear signals don't work, and the front does, but rapidly. when i was taking out the rear taillights to investigate, it worked for a few seconds when i was trying to take the black box out the left taillight, but when i tried putting it back in place, it stopped again. i checked all the wiring and bulbs and that's not the problem.........anybody know what it is? do i gotta replace that little black box or what? the brake lights work. 2001 accord ex 4dr is the model btw. help please
