Original BMW Xenon Headlight Bulb Supporting Ring for BMW 3 Series Coupe, 6 Series, X3, and Mini Cooper (2002–2008)

BMW's xenon headlight bulb supporting ring, part number 63-12-6-934-755, is the genuine retainer that holds the xenon bulb in its seat inside the headlight on the 325Ci, 330Ci, 645Ci, 650i, M6, X3, and Mini Cooper. A supporting ring like this clamps the bulb base in a fixed position so the arc lines up with the reflector or projector and the beam stays aimed where the housing intends. This ring weighs 18 g (0.63 oz), is made in Germany, and is sold individually. BMW production of this number began in March 2003.

Original BMW Parts carry a 24-month parts warranty.

This number replaced the earlier ring, 63-12-6-905-323. BMW marks the change as not interchangeable retrospectively, which means the newer 934-755 ring should not be assumed to fit vehicles that were built with the earlier part. If your car is close to the March 2003 change, check which ring is in the light now before ordering. In BMW's parts data it appears with the E46 coupe and convertible, the E63 and E64 6 Series, and the E83 X3, both pre-facelift and facelift. It is a xenon-specific part, so it does not apply to halogen headlights.

Common Questions

Can I use this ring in place of 63-12-6-905-323?
BMW lists 934-755 as the newer part, but notes it is not interchangeable retrospectively, so vehicles built with the earlier ring may need that version.

Does it fit halogen headlights?
No. BMW designates it specifically for the xenon light bulb.
