Original BMW Right Bulb Socket for E46 323Ci, 325Ci, 328Ci, 330Ci, and M3 (2000–2003)

For the right side of an E46 Ci or M3, this Genuine BMW bulb socket, part number 63-21-8-364-730, fits the 2000–2003 323Ci, 325Ci, 328Ci, 330Ci, and M3. A bulb socket, also called a bulb carrier, holds the bulbs and their contacts in position in a lamp and connects them to the wiring harness. Because it sits between the harness and the bulbs, the socket is what keeps each bulb seated and in electrical contact. BMW began producing this socket in January 1999 for the E46 two-door range. It is made in Hungary.

Original BMW Parts carry a 24-month parts warranty.

This number is the right-side version only, and BMW sells it as a single piece. BMW's parts data ties this socket to the E46 Ci engines from the M52 and M54 sixes to the S54 in the M3, which matches the coverage below.
