Bulb size chart

If you need the correct bulb sizes for a 2008 Audi S4, this page is designed to help you verify each bulb by lighting position. Instead of guessing by appearance, you can match the bulb type to the exact location on the car, which makes replacement faster and helps avoid ordering the wrong part.

The 2008 Audi S4 uses different bulbs for headlights, signal lights, parking lights, reverse lights, and interior-exterior safety lighting. Because trim and lighting equipment can vary, especially by market and body style, checking the bulb chart by position is the best way to confirm the right fit before you buy.

Fitment can vary on the 2008 Audi S4 depending on trim, package, and whether the car has factory halogen or LED-related components in certain positions.
