I'm with Gilly on this one. If I was ever fortunate enough to own a brand new MB, the last thing on my mind would be messing about with a basic operating system; headlights are not an accessory like a stereo or something. Any modification, ie altering a basic system to a improved standard, is best left to the manufacturer to come up with. Any ad hoc mod can only decrease reliability. I only hope you are not barreling down a freeway one night at 80mph and your lights go out. One more thing, why would anyone want their fog lights on all the time?
