Its not the brake light but just the rear light on the left side. At first it would go out and I would tap it and it would go back on again. but one day I went to tap it and it didn't work. I tried a new bulb and that didn't work either. the signal and brake light work in the housing and there's no rust or anything like that on it either. I have fiddled with the housing for ever and I can't figure out whats wrong. I can't see anywhere where there is no metal to metal contact. HELP. THANX in advance everyone
