I have a set of Pre-LCI E90 Mtech Fog light housing, brand new still in wrapping with tape, never used. This is for both the passenger and drivers side fog light assembly. Part numbers Left- 63176910791, Right- 63176910792. getBMWparts.com sells these for $110 per side ($220 for the set). Asking price is $160 shipped for both or $90 for one.
Here is a picture, these are brand new, never used, I unwrapped one of the lamps to show in the picture.
