Original BMW Parking Light Bulb with Socket for BMW Z4 Roadster and Coupe Xenon Headlights (2006–2008)

Built for the xenon headlight of the 2006–2008 BMW Z4, this Original BMW parking light bulb comes with its socket attached and lights the headlight halo ring on the E85 Roadster and E86 Coupe. BMW calls it a bulb socket with bulb for the parking light, and it lives inside the headlight assembly. The assembly weighs 22 g, entered production in January 2006, and is made in Romania. It is sold individually as one bulb and socket together, so there is no separate holder to buy.

Original BMW Parts carry a 24-month parts warranty.

Fitment depends on headlight type. This bulb is only for use with xenon headlights, so a Z4 with halogen headlights needs a different part. Because the bulb and socket come as a single unit, the whole assembly is changed at once. BMW's data ties it to E85 and E86 Z4 models with the N52 six-cylinder in 3.0i and 3.0si form and the S54 in the Z4 M Roadster and Z4 M Coupe, along with the 2.0i, 2.5i, and 2.5si versions that BMW's data also lists.
