a bulb is a bulb and prob all made at the same place, BMW like all big companys now get stuff made out somewhere cheap...for example my old man has a VW ( the little tiny one smaller than a polo) having brain freeze and cant think of its name but he bought it, beleiving its the usual VW german built quality car and its actually built in Brazil, hes had it 6 months fom new, already the door locks broke, and beenback a few times for various other things, think its called the FOX but the build quality for what supposed to be german engineering is crap.
