1990 accord headlights burning out

=====================

If you install a halogen lamp but don't tighten it in place properly, it
won't get the cooling it requires. I kept blowing left headlamps in my
Caravan because previous owner had lost the locking collar, which holds
the base of the lamp intimate on the body of the lamp housing.

If you've put the bulb in with the base not sitting flat against the
mating surface, it won't dissipate heat and will burn out way too soon.
I think there's only one way for the notch in the base to align with
place it fits into...

True, I'm still not going to rule out grounding. The thing is, it's only
the low beam bulbs (9006) that burn out when I put them in. The accord
also has a set of high beam bulbs (9005) and they are still working
fine. If it were the voltage regulator, wouldn't these bulbs and other
eletrical components be having problems too? It seems isolated to the
low beam bulbs.

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.
