Audi A3 2013 Bulb Size
Bulb size chart
This 2013 Audi A3 bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the right part before you buy. Because Audi used different lighting setups across trims and markets, the bulb list can vary depending on whether your A3 has halogen headlights, HID headlights, or a specific lighting package.
Use this page as a quick reference for exterior and interior bulbs on the 2013 Audi A3, including headlights, turn signals, brake lights, license plate lights, dome lights, and more. Checking the bulb location first is the easiest way to avoid ordering the wrong size or style for your vehicle.
Fitment can differ by trim, body style, and market, so always compare your installed bulb to the chart before replacing it. The 2013 Audi A3 may use halogen or HID-related bulbs in different positions, and some owners upgrade to LED aftermarket bulbs or conversion kits for brighter output or longer life. If you are switching from halogen to LED, make sure the bulb type, base, and physical clearance are compatible, since not every LED replacement will fit or function correctly. For the most reliable result, inspect the existing bulb before purchase and confirm the socket style, especially on exterior lights where the wrong part can trigger warning messages or poor beam performance.
