at first i had Stock bulbs, then my drivers side burn'd out so i got a pair of h4 upgrades.
installed them then about 5 months after using them. drivers side BURN'd out again.

so i bought some good $38.00 bulbs on ebay.

NOW tonight it burn'd out again.

ive changed the dimmer switch. (even though i know thats not the problem)

but what should i look at and try to fix????????

so that i can QUIT buying bulbs,
this summer im out for college, and i dont need to be dealing with problems with my truck.

ANY advise greatly appreciated.

I agree. With a bad ground, the current could be rapidly starting and stopping just like constantly turning the lights on and off. It would not be that noticeable, and would affect bulb life.

Also check your bulb connectors. Make sure there clean and tight. A loose connector can drive the resistance up causing the bulbs lifr to deminish rapidly.
