For the 2019 Audi A5, the low-beam and high-beam headlights both use D5S bulbs. This fitment data does not list separate bulb sizes for low and high beam, so the same D5S application applies to both functions.
- Fog lights: H8 LED
- Cornering lights: H8 LED
- Front turn signals: 12181NA
Most other exterior lighting is listed as LED, including the reverse, brake, center stop, daytime running, license plate, parking, front and rear side markers, tail lights, and rear turn signals. Interior lighting is also primarily LED, including the dome, map, trunk, vanity, and general interior lights. The glove-box light is listed separately as bulb 2821.
No projector or non-projector headlight distinction is specified in the supplied fitment data. Confirm the existing housing and connector before ordering, particularly when replacing factory LED assemblies.
