Audi A3 Bulb Size By Years
Misconception: a single bulb size fits every car light, so you can pick anything that looks right. It seems true because many bulbs look similar and some online listings use generic labels, which makes the selection feel simpler than it is.
What is true is that your 2010 Audi A3 has specific bulb types for low beam, high beam, turn signals, and interior lights. Think of it as a mental model: socket shape, wattage, and beam pattern matter more than appearance. The list on this page maps those exact sizes to each function, so you can match replacements confidently.
Implications and quick recap: use the chart as a first check, then verify with your owner’s manual and a physical socket comparison. Quick tests: compare part numbers, check fit, and test brightness.
