Why would a headlight keep going out?

Answer 1

If it keeps burning out it may be a bad groumnd. ... going out but not burning out is poor connections, or damaged wiring. The headlights, and most other lights, kept going out in my 1993 Escort because of a dying alternator. Apparently, it was sending too much juice into the electrical system. If you're experiencing similar problems I would suggest checking the alternator just to be sure it's not the same problem. Since I replaced the bad alternator all bulbs are fine and are no longer needing to be replaced every couple weeks or so. I would suggest questioning the mechanic that removed your fog lights. Did they tape the cut wires or leave them exposed?
