Audi Q5 2020 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 2020 Audi Q5 by lighting position, so you can match the correct replacement before you buy. Because Audi used different lighting setups depending on trim, market, and body style, checking the bulb location is the safest way to confirm fitment.
On the 2020 Audi Q5, many exterior and interior lamps are LED-based, while a few positions use specific service bulbs such as 921, 194, H8 LED, and 12174NA. Use the chart on this page to identify the exact bulb type for the headlight, tail light, brake light, license plate light, cargo area, and other locations on the vehicle.
Fitment can vary with trim package, lighting package, and regional equipment, so always compare the bulb position on your vehicle with the chart before ordering. Some Q5 models use factory LED assemblies, while others may have halogen-style service bulbs or LED modules that are not meant to be swapped like a standard bulb. If you are considering aftermarket LED conversions, check for proper connector style, beam pattern, and warning-light compatibility. The best practice is to inspect the installed bulb or housing first, especially for exterior lights, because the same model year can have different parts depending on options.
