2005 Audi A6 bulb fitment varies by headlight configuration. The high beam is listed as either D2S or H1, while the low beam uses D2S, H7, or H7 LED. Confirm the bulb currently installed and the headlight assembly type before ordering, especially when replacing a low-beam or high-beam bulb.
Fog lights are listed with H7 and H7 LED options. Other useful exterior fitments include:
- Front turn signal: 3457A or 2827
- Reverse light: 921
- Brake and tail lights: 7506
- Center stop light: LED
- License plate and vanity lights: 6418
- Rear turn signal: 12496
Interior applications include 2821 for the courtesy light, 47830 for the dome and map lights, and 2825 for the glove-box and one trunk-light application. The trunk light also has a listed 6486X option. Because several locations have multiple fitments, verify the existing bulb and socket before purchase.
