Also interested for more info on the clear lens swap...
Also for the general Z4 crowd, what would amber removal entail? All post-facelift (06-08) models already have clear lenses, it's the bulb that flashes yellow correct? I know Starscream coded his car to Euro settings so the eyelids never lit up as DRL's. So in essence he cleared out his ambers without physically modifying them -- while retaining ambers for necessary functions, ie turn signals.

I guess maybe you could "clear out" the ambers if you swapped the outer bulb of the "yoke" as Starscream referred it to a clear one?
