And now for something completely different...
I purchased a set of H1 fog lamp bulbs for my '99 SLK produced by a company called Hiper
http://www.24hiper.com from a place called auto indulgence
http://www.autoindulgence.com and installed them about a year ago along with some H7 headlight bulbs. They have not burned out nor have I had any problems with them. As for their performance the difference is... pardon the pun... night and day.
