Audi SQ5 2023 Bulb Size
Bulb size chart
This page for the 2023 Audi SQ5 helps you verify bulb sizes by lighting position, so you can match the correct replacement before you buy. Because Audi uses LED lighting on most exterior and interior locations on this model, it is important to check the exact lamp position rather than assuming one bulb fits every light.
Use this guide to compare the front, rear, and interior lighting points on your SQ5, including headlights, fog lights, brake lights, turn signals, license plate lights, and cargo-area lighting. The bulb chart is organized to make replacement easier and to reduce the chance of ordering the wrong part.
Fitment can vary by trim, lighting package, market, and body style, so always confirm the installed bulb or assembly on your specific vehicle before purchasing. The 2023 SQ5 is heavily LED-equipped, but some locations still use replaceable bulbs such as 921 for the back-up reverse light and rear fog light, and 2825 for the glove box light. If your vehicle has had aftermarket LED conversions or previous repairs, the installed parts may not match the original equipment listing. Checking the existing bulb, connector style, and housing design before ordering is the safest way to avoid compatibility issues.
