Re: 1990 accord headlights burning out
You have four headlights, two hi and two low, no dual filiment bulbs,
correct? Forget grounding problems, you have five seperate grounds and only the low beams are grounded near the lights, I looked at a 1990 Accord wiring diagram. Here in the city, I never use high beams and if you never use a bulb it should not burn out. Look at the light assemblies, are there any cracks or bad gasketing so cold water can get on the bulbs. When you installed the bulbs, did you touch the glass part of the bulbs? If you have dual filiment headlights and you loose a ground, you end up with three filiments in series, that is each filiment sees 4 volts instead of 12 volts and each filiment drops to about 10% of normal wattage. Under voltage will not burn out bulbs, only motors. Check your voltage with the enging running, as noted in a previous reply.
