Audi A5 2019 Bulb Size
Bulb size chart
This page covers the 2019 Audi A5 and helps 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 setups depending on trim, market, and body style, it is smart to confirm the bulb type for each location before ordering.
For the 2019 Audi A5, many exterior and interior positions use LED lighting, while a few serviceable bulbs remain in specific spots such as the glove box, fog lights, cornering lights, and headlight assemblies. Use the bulb chart on this page as a position-by-position guide when replacing a failed bulb or planning an upgrade.
Fitment can vary on the 2019 Audi A5 depending on trim package, factory lighting equipment, and whether the car uses halogen-style service bulbs or full LED modules in a given location. That matters especially for aftermarket conversions, since an LED replacement may not fit or function correctly if the housing, connector, or control system is different. Before buying, check the bulb already installed in the vehicle whenever possible, compare it to the chart, and confirm whether your A5 has the same lighting package as the listed application. This is the safest way to avoid ordering the wrong part and to make sure the replacement works properly without warning messages or fitment issues.
