Hmmm...my car is from Japan and has unusual taillight plastic. On both sides, it looks like one section was almost "taped over" to break up the solid red plastic. I saw this in shogun's post:
"Elimination of rear side marker lamp spacing standard of the Government of Japan or acceptability of the European Community rear side marking lamp spacing standard as equivalent to the Government of Japan's standard."
I know this is not a "rear side marker," but is this related to "lamp spacing?" Is this why my Japan version of the 750il has the unusual black space in the taillight plastic? Does anyone else have a 750il with rear taillight plastic that is not solid red? I will post a pic if need be.
