Plus they look nicer and neater than the ones you have, they come in 25w and 50w, I think I used 25w. My LED tail lights have been on for 4 years now with no problems whatsoever, check out the link below.

EDIT: I just noticed you have a 2005, apparently from everything I've read over the years, BMW changed something starting in 2003, so the 2003 and up models have trouble when installing LED tails, mine is a 2002.
