Original BMW Left Rear Light Bulb Holder for Trunk Lid, BMW 325i, 328i, 330i, 335i, and M3 (2006–2008)

This Original BMW bulb carrier holds the bulbs for the left-side tail light section built into the trunk lid on 2006–2008 E90 3 Series sedans and the 2008 M3. BMW calls it the bulb socket for the rear light in the trunk lid, left. A bulb carrier of this type sets each bulb in its reflector chamber and feeds it power through contacts molded into the carrier body, so a damaged carrier can take out several lamp functions at once. This one is made in Poland and comes as a single piece.

Original BMW Parts carry a 24-month parts warranty.

BMW lists this number as the bulb socket for the rear light in the trunk lid, left. It replaced the earlier 63 21 6 937 475, and BMW marks the change as exchangeable retrospectively, which lets the newer carrier go into cars built with the old one. Carriers like this usually last the life of the car, although condensation inside the light can damage them and affect the whole assembly.
