Original BMW H7 Low Beam Headlight Bulb Socket for E46 BMW 3 Series and M3 (1999–2006)

Built for the H7 low beam bulb, Original BMW bulb socket 63-12-8-380-206 holds the bulb in the headlight and makes its electrical connection on E46 BMW 3 Series and M3 models from 1999–2006. A headlight bulb socket locks the bulb into the reflector and links it to the car's wiring harness. BMW gives a weight of 52 g (0.1 lb), and production of this number started in January 1998. The socket is made in Poland and sold individually. Sockets corrode with age, and once the contacts stop making a good connection, the low beam will not light even with a new bulb.

Original BMW Parts carry a 24-month parts warranty.

This number supersedes 63-12-0-391-172, and BMW rates the change as exchangeable retrospectively, so an early E46 still carrying the older socket takes this one with no changes. BMW's parts data uses the same socket across the E46 range covered here, from the M52-powered 323i and 328i through the M54 and M56 325i and 330i models and the S54-powered M3. BMW shows no left or right split for this number, and it is specific to the H7 low beam position.

Common Questions

Which bulb does this socket hold?
It is the socket for the H7 low beam bulb in the E46 headlight.

My low beam stays dark with a new bulb. Could the socket be the problem?
Yes. A corroded socket can stop making good electrical contact with the bulb, which keeps the low beam from lighting.

Does it replace 63-12-0-391-172?
Yes. BMW supersedes that number with this socket and rates the change as exchangeable retrospectively.
