Hi guys,not sure if anyone started a thread similar to this but as mentioned I would like to convert the old spec tail lights on my 2003 model e46 m3 to the LED spec and just wanted to find out if anyone has done this or had any problems with this conversion.i have read Afew threads and some guys say the LED flickers when the car starts up and you need to flash the car as it will pick up an error with the light?also read there is a plug and play adapter/harness that can be bought to connect up for a easy and quick installation?any help will be much appreciated :thumbs: it is a set of original LED tail lights .thanks :thumbs:
