For the 2007 Audi A4, both the low-beam and high-beam headlights use D1S bulbs. Check the existing headlamp assembly before ordering, since this fitment data identifies D1S for both functions but does not specify additional headlight configurations.
Front fog-light options are listed as H11 LED and H16 LED, so confirm the fog-lamp housing and connector on your vehicle before purchase. Other notable exterior lighting includes:
- 7506: front and rear turn signals, reverse lights, and daytime running lights.
- 7506R: brake lights.
- LED: center stop light.
- 6418: license-plate light.
- 2825 or 98: parking, front side-marker, and step lights.
- 5007: tail lights.
Because several positions have more than one listed option, verify the bulb currently installed or match the socket and lamp assembly before replacing it.
