Burg Boxster and this board rocks! I had the same problem tonight, drove home with my high beams on and searched the boards and found this thread. Switched the high beam bulb with the low beam until I get a couple of new bulbs. I've had japanese cars so I'm used to havinig just 1 bulb for hi/lo. Would have never thought the lo was burned out (even after looking in the manual since they both burned out at the same time.)
