Audi S4 2022 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 2022 Audi S4 by lighting position, so you can match the correct replacement before you buy. Because Audi used LED lighting across most exterior and interior locations on this model, checking the exact lamp position is the best way to avoid ordering the wrong part.
Use the bulb chart for the 2022 Audi S4 to identify the lighting function you need, such as low beam, high beam, brake light, reverse light, or interior lamps. Trim level, market, and body style can affect the exact setup, so it is always smart to confirm the bulb type on the vehicle itself when possible.
Fitment on the 2022 Audi S4 can vary by trim and lighting package, and some cars use different assemblies depending on market or body style. Many exterior positions are LED from the factory, which means the bulb may be integrated into the housing rather than replaced as a separate halogen-style bulb. If you are considering an aftermarket LED conversion or replacement, compare the original equipment design carefully, since some upgrades may require resistors, adapters, or a full assembly swap. Before ordering anything, check the installed bulb, connector, and housing style on your car so you can confirm compatibility and avoid returns.
