This 2011 Audi A4 bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right replacement to each lamp on the car. Whether you are replacing an exterior signal bulb, an interior courtesy light, or a headlight bulb, checking the exact location first can save time and prevent ordering the wrong part.

The 2011 Audi A4 uses different bulb types depending on the lighting setup, and some positions vary with trim, market, body style, or factory lighting package. This page organizes the bulb chart by function so you can quickly find the fitment for your specific A4 before you buy.

For best results, compare the bulb listed here with the one already installed in your car before purchasing, especially if your A4 has had previous repairs or aftermarket lighting changes. Trim and package differences can affect fitment, and halogen and HID-equipped cars may use different bulbs for the same lamp position. If you are considering LED replacement bulbs or a conversion kit, make sure the new bulb matches the socket, size, and beam pattern requirements for that location. When in doubt, remove the old bulb and confirm the marking on the base before ordering.
