    Evening gentlemen. I have a 1992 f150. Same headlight bulb for 10 years. It blew. I replaced it with a 9007 sylvania bulb. ...blew it in 4 days. Replaced it, same result. Never touched the biob with my fingers either. Any ideas why Im frying bulbs? Sealed in nicely, no water intrusion. ....hasn't rained either. Perfect weather. Any ideas? Thx in advance. ..

    Are you sure it's the bulb and not a burnt connector?

    IF the connector is good....I would check the running voltage. If the regulator goes sky high...it will blow your bulbs. I have had that happen to me personally.

    .


    Same plug every time I highly doubt it's a regulator issue, but you never know.
    I would measure the draw, and check for exposed wire like Lowend said.
    Something might be rubbed through??

    Good luck.

    Connector is like new. I'm going to check voltage I guess. Both bulb's basically blew up. No glass left around them upon removal....
