Audi A3 2010 Bulb Size
Bulb size chart
This 2010 Audi A3 bulb size guide helps you verify the correct bulbs by lighting position before you buy replacements. Because the A3 could be equipped with different headlight and trim combinations, the right bulb can change depending on whether your car has halogen or HID headlights and on the market it was sold in.
Use this page to match each exterior light on your 2010 Audi A3 to the proper bulb type, including headlights, parking lights, turn signals, brake lights, reverse lights, and license plate lights. Checking the bulb by location is the easiest way to avoid ordering the wrong part.
Fitment can vary by trim, lighting package, body style, and region, so always compare your installed bulb before purchasing. The 2010 Audi A3 may use different bulbs for halogen versus HID setups, and some fog light listings may point to LED-style replacements or compatible aftermarket options rather than a single factory bulb. If your car has been converted from stock lighting, or if a previous owner installed non-original parts, the bulb listed on the page may not match what is currently in the housing. For the best results, remove the old bulb, check the base and marking, and confirm the socket style before ordering.
