For the 2020 Audi SQ5, both the low-beam and high-beam headlights are listed as LED. The fitment data does not provide a replaceable halogen-style bulb number for either headlight function, so confirm the original headlamp design before ordering a replacement or upgrade.
Front turn signals, brake lights, the center stop light, cornering lights, daytime running lights, parking lights, front and rear side markers, tail lights, rear turn signals, license-plate lights, and the trunk light are also listed as LED. These systems may use integrated LED assemblies rather than standard replaceable bulbs.
Fog-light fitment has an important variation: the data lists either LED or 921. Check which fog-light configuration is installed on your SQ5 before purchasing. The reverse lights use 921 bulbs, while the glove-box light uses a 2825 bulb. Match the existing socket and housing when servicing these replaceable locations.
