Bulb size chart
This 2007 Audi A4 bulb size page is designed to help you verify the correct bulbs by lighting position before you buy replacements. Whether you are changing a headlight, a turn signal, or a license plate lamp, checking the bulb chart by location makes it easier to match the part to the exact light on the car.
Because trim and lighting equipment can vary, the bulb list for a 2007 Audi A4 may differ by market and body style. Use this page as a practical reference for the most common exterior and interior bulb positions, and compare the bulb type on your vehicle before ordering. That is the safest way to avoid buying the wrong fitment.
For best results, confirm whether your A4 uses halogen or HID/xenon headlamps, and note that some lighting functions may use different bulb setups depending on trim or package. Aftermarket LED conversions can also change fitment needs, beam pattern, or warning behavior, especially for headlights, fog lights, and turn signals. If possible, remove the installed bulb and match the number printed on it before purchase, since that is the most reliable way to verify fitment on a 2007 Audi A4.
