Original BMW Headlight Turn Signal Bulb Socket for BMW 528i, 540i, and M5 E39 (1997–2001)

Built to hold and power the turn signal bulb in the headlight assembly, Original BMW bulb socket 63-12-8-369-219 fits the E39 BMW 528i, 540i, and M5 from 1997 to 2001. The socket gives the bulb a secure seat and carries current to it when the signal is switched on. BMW names it a bulb socket, and it weighs 18 g (0.63 oz). It is made in Germany and has been in production since April 1996, so it covers the E39 from the start of the run. Any bulb socket of this type has two jobs: it holds the bulb against vibration, and it gives the bulb's base clean electrical contact so the lamp lights at full output.

Original BMW Parts carry a 24-month parts warranty.

A worn socket shows up in a few typical ways. The turn signal may work only some of the time or stop working, usually from poor electrical contact. The socket housing can burn or melt from overheating or electrical resistance. Corrosion or moisture can build up and leave the bulb dim or flickering. BMW applies this one number to the E39 528i with the M52 six, the 540i with the M62 V8, and the M5 with the S62 V8. BMW's parts data shows no supersession and no earlier number for it.

Common Questions

What are the signs of a failing turn signal socket?
Look for an intermittent or dead turn signal, a burnt or melted socket housing, or corrosion and moisture that leave the bulb dim or flickering.

Does this socket fit the E39 M5?
Yes. BMW applies it to the 2000 M5 with the S62 engine, as well as the 528i and 540i.

Is this a dealer-equivalent part?
Yes. It is an Original BMW part made in Germany, sold new and unused.

A fresh socket is a small fix that keeps an E39's signals bright and reliable.
