hopefully this helps a lot of people as i was having a hard time buying the correct blacklines... and even figuring out if there was one for my car.
i have a 04/08 build date. halogen. 128i. the blacklines that are 63212225282 part number work straight plug and play. the whole tail light including the lines light up. no lights on the dash. all good. i would also recommend getting them from this place on ebay, they were the least expensive i have found

they are 300 buy it now, and only 60 shipped. so total, 360, and i know they work, this is where i got mine from. happy new year folks, i just did this myself and it just maybe my favorite mod
