Audi SQ5 2021 Bulb Size
Bulb size chart
This page covers the 2021 Audi SQ5 and helps you verify bulb sizes by lighting position, so you can match the correct replacement to each exterior and interior lamp. Because Audi used LED lighting for most of the SQ5’s functions in this year, it is especially important to confirm the exact position before ordering anything.
Use the bulb chart below to check common fitment points such as the headlights, fog lights, brake lights, turn signals, license plate lights, tail lights, daytime running lights, and interior lamps. The goal is to make replacement easier and reduce the chance of buying the wrong bulb for your 2021 SQ5.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb position on your vehicle with the chart before purchasing. On the 2021 SQ5, many exterior lights are LED assemblies rather than simple replaceable bulbs, while a few locations still use serviceable bulbs such as the back up reverse light, rear fog light, glove box light, and some cargo-area applications. If your SQ5 has been modified, or if you are considering an aftermarket LED conversion, check for warning messages, polarity issues, and beam pattern problems before installing anything. The safest approach is to inspect the installed bulb or lamp assembly first, then buy a replacement that matches the original setup exactly.
