Indeed, the fogs are in the bumper...I think we all knew that, and the inner lens are aux. driving lights on my Bekker supplied lights also. I'm of the thought that MB wouldn't make an entirely different headlamp housing...just upgrade/re-configure the wiring and lens if need be ...and perhaps the reflectors as you suggest. Makes sense.
Bring over your "500E" only lamp when you pick up the deed for the island and we'll put them next to each other to see what the big dollar difference is. BTW, you WILL have to evict some indingents before moving on the island , though...I bet if you flash those lights on them at nite they'd boogie away real toot sweet.
