Why do my headlights keep blowing?!?
2003 Disco w/ 108k
Anybody have a theory as to why I blow headlights alternately about every 6 months?
First, the left one blew, and we replaced it with a good "silverstar" from autozone. Actually, I bought a pair and hung onto the other for later. About 6 months later, the right one blew, and we used the bulb. 6 months later, the left one blows again, same process ensues...
We have now been through 3 new sets of headlights, all at roughly the same 6 months apart, and yesterday...yep, you guessed it...the left one blew again!
Any thoughts?

I had a Mazda that did the same thing. Are you driving on especially rough roads a lot? The Mazda dealer claimed that with a sport (read 'firmer') suspension, the filaments could be subject to more stress when the bulbs have been on a while. I don't know if I've ever believed this theory since the bulbs in my other cars have been fine, but it could be a contributing factor.
Also, is there any chance that moisture could be getting in to the headlight housings? I have seen a lot of bulbs blow out quicker in a damp environment...

When replacing with Silverstars are you making sure that you do not touch them barehanded?...they are notoriously short lived bulbs, especially if not handled correctly...not unusal for them to blow within a year of install.
Have you tried different lightbulbs 1st or are you replacing each blown bulb with more Silverstars?

Also, there is no evidence of moisture getting inside the housing or anything, and we do have a gravel driveway, but nothing I would call rough.
Open to suggestions.
