A used OEM Audi lower tail light bulb socket holder / harness (part 4L0945221A) for the Q7. This genuine Audi component secures the bulb socket and carries wiring to the taillight assembly. Corroded contacts or broken plastic tabs in this holder can cause intermittent brake or tail lamp failure—replacing it restores a positive electrical connection. Fits the left or right side.
