Original BMW Bulb Socket for Left Side Panel Rear Light, BMW E93 Convertible 328i, 335i, and M3 (2007–2010)

Only the E93 convertible uses this part: the Original BMW 63-21-7-178-383 is the left bulb carrier for the rear light in the side panel, holding the bulbs and their contacts in the side panel tail light section of the 2007–2010 BMW 328i, 335i, and M3 Convertible. BMW calls it the bulb socket, rear light side panel, left. A bulb carrier is the plate that holds several bulbs in their positions and carries current to them through one connector, so it can be replaced without changing the lens or housing. This carrier weighs 83 g and is made in Germany. BMW's parts data shows production from November 2006.

Original BMW Parts carry a 24-month parts warranty.

This carrier serves the side panel section only, on the left. Check both the side and the lamp section before ordering. Because BMW ties this carrier to the E93 chassis, sedan, wagon, and coupe 3 Series cars of the same years do not take it.
