Genuine OEM Audi tail light bulb holder 4F5945221B—used, left rear lamp mount from a donor vehicle. This tail light or lamp bulb holder secures the bulbs and provides electrical contact for the taillight assembly. A common failure point on these holders is corrosion of the bulb contacts, which can trigger bulb-out warnings or cause intermittent lighting at the rear. The part fits Audi A6, A6 Quattro, and S6 models equipped with 2.8L to 5.2L V10 engines.
