Original BMW Bulb Socket, Side Panel Rear Light, for BMW X3 F25 (2011–2017)

Made in Mexico for the F25 X3, this Original BMW bulb socket holds the bulbs in the rear light mounted in the body side panel of 2011–2017 BMW X3 models. BMW names it the bulb socket, rear light side panel. The socket weighs 95 grams and is sold as a single piece. BMW shows production of this number beginning in September 2010. A bulb socket carries the bulbs and their electrical contacts and locks into the back of the light housing, so the bulbs sit in the right position behind the lens.

Original BMW Parts carry a 24-month parts warranty.

Engine choice makes no difference with this socket. BMW applies the same number to every F25 variant, from the N20 four-cylinder in the xDrive28i to the N55 six in the xDrive35i and the N57 diesel in the xDrive35d, along with the N47N, B47, and N52N versions. The deciding detail is the light itself. This carrier belongs to the rear light in the side panel, so match it to that light before ordering.
