Bulb size chart
This page covers the 2020 Audi A5 bulb sizes by lighting position, so you can quickly match the correct replacement before you buy. Use it to verify the bulb type for each location on the car, whether you are replacing a small interior lamp or one of the exterior lights.
The 2020 Audi A5 can use different lighting setups depending on trim, market, and body style, so the safest approach is to check the bulb chart by position. That helps you avoid confusion between similar-looking bulbs and makes it easier to find the right fit for your specific A5.
Fitment can vary on the 2020 Audi A5, especially if the car has different lighting packages or has been updated with LED equipment. Some positions may use halogen-style bulbs on one version and LED units on another, and aftermarket conversions can change what is actually installed in the vehicle. Before ordering, check the bulb currently in the housing and compare it with the chart on this page, since the installed part is the best confirmation of fit. If your A5 has been modified, or if a previous owner changed the lighting, the original factory listing may not match what is in the car now.
