Original BMW Turn Signal Bulb Socket for BMW E38 740i, 740iL, and 750iL (1995–2001)

Built for the E38 7 Series, this Original BMW bulb socket holds and powers a turn signal bulb in the 740i, 740iL, and 750iL from 1995–2001. A turn signal socket does two jobs. It locks the bulb in place inside the lamp, and it gives the bulb the electrical contact it needs to flash when the signal is switched on. BMW calls this part simply "Bulb socket." It weighs 13 grams, and BMW has produced it since September 1994. The socket is made in Germany and sold individually, as one piece.

Original BMW Parts carry a 24-month parts warranty.

BMW uses this one socket on the E38 740i, 740iL, and 750iL, so the same part fits the M60 and M62 eight-cylinder cars and the M73 twelve-cylinder 750iL. Signs of a failing turn signal socket include an intermittent or dead turn signal from poor contact, a burnt or melted socket housing from heat or electrical resistance, and corrosion or moisture that leaves the bulb dim or flickering.
