My 2004 saab 93 keeps blowing headlight bulbs, HELP!!?

My 2004 saab 93 keeps blowing headlight bulbs, HELP!!

Driving me mental!!

Sometimes they last for weeks, and other times they blow after a few minutes!!
Doesn't matter if they are cheap bulbs or exspensive ones.

They are the correct size.

Any ideas please???

Check the battery voltage with the engine running using a meter across the battery - it shouldn't be more than 14.5v. If it is, the voltage regulator in the alternator needs replacing.
