Bulb size chart
This 2009 Audi A5 bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right part to the right socket before you buy. Because the A5 could be equipped with different lighting packages, the exact bulb type may vary by trim, market, and body style.

Fitment can differ between halogen and xenon-equipped cars, and some A5 models use LED components in certain positions while others use replaceable bulbs. Aftermarket LED conversions can also change the bulb type you need, especially in the headlights and daytime running lights.
