Both headlights inexplicably blown out - please help!

[theswedishthing]

Could be a simple fix I don't know about, but both headlights not working on my stock '03 P5. Bulbs look ok, high beams, tails, signals, orange runners, and fog lights work, but neither headlight. Checked both fuse boxes and everything looks ok, even the main head fuse. Any ideas here? My wife and I need our car to work at night!

Thanks..

Gotta be the turn signal switch that turns the lights on and off if everything else is working. There may also be a relay with the fuse box that closes a normally open switch to turn the headlights on. Those occasionally go bad as well and would be a simple fix.

^What he said. Swap the headlight relay with another relay in the fusebox and see if the headlights work.

Got it sorted - Like I said, both the bulbs looked good when I checked them, but the relay's seemed to be good, and decided it wasn't the switch because it activated the fog lights etc. Anyway, just actually tried replacing the bulbs and that was the problem - they somehow both just burned out at the same time... Thanks guys!

Thought you said the bulbs were good! I would recommend replacing them with HIDs. Our cars are notorious for blowing out headlights and foglights. I replaced all four with HIDs, never had a problem again

I've seen a couple of guys blow both bulbs at once recently. A cheap DDM HID kit can be had from xenonexpert for less that $100. I did that more than a year ago and have never looked back!
