Audi A3 2019 Bulb Size
Bulb size chart
This page covers the 2019 Audi A3 and is designed to help you verify bulb sizes by lighting position, so you can match the correct replacement to the exact lamp on the car. Because Audi used different lighting packages and trim combinations, the bulb chart below should be read by location, not just by model name.
For the 2019 A3, many exterior lighting functions use LED assemblies, while some interior locations still use replaceable bulbs. That means the right fit can depend on whether your car has LED headlights or HID headlights, plus the market and body style it was built for.
Before buying replacements, confirm your A3’s trim, lighting package, and headlight type, since halogen-style and LED-equipped cars can use different bulb setups. This is especially important on aftermarket conversions, where a previous owner may have changed parts or added nonfactory lighting. If you are unsure, remove the installed bulb and compare it before ordering, because the safest way to avoid a mismatch is to verify the actual bulb in the vehicle. Even when the chart lists an LED function, the assembly may be sealed and not serviced with a separate bulb, so check the specific lamp location carefully.
