im having the same problem. im going to rehash this thread in case someone can advise me.
im gonna check with a family member, but say i cant manage to take my lights apart and rewire them like OP did, is my only other option to buy a whole new set? are there any shops you can take it to and have them fix it, short of buying a new set of lights?
these are the LED tail lights i have on my 07 E90: http://www.myhotbimmer.com/bmw/Optio...1-12129/609954
