For the 2020 Audi A5, the supplied fitment data lists both H16 LED and H8 LED options for the low-beam and high-beam headlights. Confirm the existing bulb and headlight configuration before ordering, as these options should not be treated as interchangeable without verification.
The fog lights use an H8 LED bulb. The cornering light is listed with an H11 bulb. No front turn-signal or reverse-light bulb fitment is provided in the supplied data.
For additional vehicle lighting, the engine compartment uses a 578 bulb, while the glove-box and interior lights use 194 bulbs. Check the original bulb or vehicle-specific housing when replacing any light, particularly where multiple headlight options are listed.
