For the 2012 Audi S5, both the low-beam and high-beam headlights use D3S bulbs. The supplied fitment data does not identify a projector or non-projector headlight variation, so verify the existing bulb and headlamp assembly before ordering.
Fog-light fitment is listed with two options: H11 LED and H16 LED. Confirm the fog-lamp configuration on your vehicle before purchasing. The front turn signal uses a 64136 bulb, while the reverse light and rear turn signal are listed as 921.
- Brake, center stop, daytime running, tail, and rear side-marker lights are LED.
- License-plate and dome lights use 6418.
- Parking lights, front side markers, courtesy, glove-box, map, and trunk lights may use 2825 or 98.
Because several locations have alternative listings, match the replacement to the bulb currently installed in your S5.
