Hi all, I have a 1999 boxster and both headlights went out on me.

I had a dealer installed a unit to turn on day time running lights a few years ago because I had to import the car to Canada.

Could this be the cause I have no lights?
I tried replacing fuses, maybe I didnt get replce the right one?
Can both headlights go out at the same time cause by fuse?

High beams - ok
Fog lights - ok
Turn signal - ok

Any thoughts and suggestions would be greatly appreciated.
Thanks

ps
in the mean time, I switched the the sockets around high beams to low beams. I have driving lights at night when I turn on my high beams. Hope this is ok

 

I had the same problem on my 2001 Boxster S last year. Replaced the bulbs and it worked for about 2 months and they went out again. Took it to the local Porsche dealer and they checked it and found a switch that was bad. Had that replaced and have had no problems since.
