Robert Mudry suggested buying a set of white tail lights as part of adding rear foglights to an E46. Six month after its introduction, white tail lights and blinkers are available for the E46. Part numbers and prices for the E46 4-door are:
one set, front & side 82 19 9 416 994 147 DM / 75.16 Euro one set, rear 82 19 9 416 997 398 DM / 203.49 Euro
Make my day - buy a set for your 323i and annoy a New Jersey marketer. Just kidding. Actually, I do appreciate a lot of what they have done.
