Original BMW PY21W Turn Signal Bulb Socket, Left or Right, for BMW 2 Series, M2, and X1 (2014–2022)

Built for a PY21W bulb, this Original BMW turn signal bulb socket holds the bulb in the front turn signal of the BMW 2 Series, M2, and X1 from 2014–2022. The same part fits the left or right side. A bulb socket locks the bulb into the lamp housing and carries power from the harness to the bulb's contacts. BMW uses this socket with both halogen and xenon headlights on cars that have a bulb-type turn signal. It weighs 16 grams.

Original BMW Parts carry a 24-month parts warranty.

BMW has produced this socket since November 2013. It replaced the earlier 63-11-2-993-445, and BMW marks the change as exchangeable retrospectively. The socket is item 14 in BMW's headlight parts diagram. It is priced and sold individually, so order two to replace both sides.
