Original BMW Left Bulb Socket for BMW 3 Series E46 Coupe and Convertible (2000–2003)

This Original BMW bulb socket is the left-side bulb holder for the E46 3 Series coupe and convertible, offered for the 323Ci, 325Ci, 328Ci, 330Ci, and M3. BMW names the part bulb socket, left, and began producing it in January 1999. It is made in Hungary and sold as a single socket.

Original BMW Parts carry a 24-month parts warranty.

A bulb socket holds the bulb in its lamp housing and carries current to the bulb contacts, so a cracked or corroded socket can stop a good bulb from lighting. BMW applies this number to the E46 coupe and convertible models, including the M3 and M3 CSL with the S54 engine. Other engines in that range include the M52 in the 323Ci and 328Ci and the M54 in the 325Ci and 330Ci. Because BMW makes the socket by side, a car needing both takes this part plus its right-side counterpart. Genuine BMW parts carry the BMW roundel and a short seven-digit number, which reads 8364729 on this socket, and some also show the stamp of the supplier that built them for BMW.
