Low beam bulb keeps blowing E30

4 posts in this topic

My left low beam bulb blew, replaced the fuse and bulb and now it blows new bulbs immediately.

I have gone through at least 4 new bulbs that were all used previously. There is a relay that supplies both sides and I have tried 3 different relays. At idle the voltage on the the back of the bulb is 13.0.  The earth is common to the park light and that works ok.

The car is a pre facelift 325  E30 that has had facelift headlights fitted.

Any ideas ?

Are you touching the glass of the bulbs when you are putting them in? What type of bulbs are you using?
