This 2008 Audi A4 bulb size guide helps you verify the correct bulbs by lighting position, so you can replace the right lamp without guesswork. Whether you are changing a headlight, interior bulb, or exterior signal light, using the correct fitment makes the job faster and helps avoid mismatched parts.

The 2008 Audi A4 uses a mix of HID, halogen-style, and small wedge or festoon-style bulbs depending on the lamp location. Because trim level, lighting package, market, and body style can change the exact setup, it is smart to confirm each bulb by position before ordering replacements.

For best results, compare this page with the bulb already installed in your car, especially if your A4 has been modified or fitted with aftermarket lighting. Some positions may differ between halogen and LED conversions, and fog light or interior lighting upgrades can affect the bulb type you need. If your car has a different trim or package, the listed bulb size may still vary slightly, so checking the old bulb before purchase is the safest way to avoid returns and fitment issues.
