Hey,

I have a 1992 Honda Accord with over 150,000 miles on it. Recently (within the past few months) the low beam headlight bulb has been burning out at a rate of 1 per month. This is the only bulb that has blown out on the car, and I'm just wondering what the causes could be. The fuses seem fine, the wiring has no obvious physical damage, and there are no other electircal problems that I know of. The light is on the driver side. Any ideas? Thanks.

Very strange.

Wild guess: Getting body oil on the bulb, when it's replaced.

Make sure contacts are clean. Don't really know or have any likely explanations.

Contacts are pretty clean, I never touched the bulb (I figured that and possibly that it was a cheap bulb when I replaced it originally, but I replaced the other side too because they were old, and that one functions fine).

Any chance it could be a relay that's sending too much power?

Thanks again man

1. You may have a bad combination light switch. Normally these bulbs are 60 W high beam and 55 W low beam. If your combination light switch is bad, it may somehow be allowing too much voltage through the low beam circuit. Both high and low beam circuits to each headlight are protected by their own 10 A fuse in the under-dash fuse/relay box.

Flow is from + battery terminal, to the under-hood fuse/relay box (40 A), to the combination light switch, to the under-dash fuse/relay box (10A fuse to the high beam and a 10 A fuse to the low beam of each headlight--therefore, four 10 A fuses overall), to the headlights. That's the picture. The only thing that really makes sense is some problem with the switch. Maybe someone else has an idea.

2. Make sure you don't have the wrong size fuse in any of the headlight fuse slots.

No. I have a US 1992 Accord EX, power everything ABS, all the good stuff, but the car was never equipped (or designed for) DRLs.

When you solve the problem, let me know the solution.
