Paragon 14 Report post Posted October 18, 2017 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 ? Quote Share this post Link to post Share on other sites
