This 2014 Audi A4 bulb size guide is designed to help you quickly verify the correct bulb type by lighting position, so you can replace the right lamp without guesswork. Whether you are changing exterior lights, interior bulbs, or cargo-area lighting, this page organizes the fitment information by location for easier shopping and installation.

The 2014 Audi A4 can use different bulb setups depending on trim, lighting package, body style, and headlight type. That means the bulb for one position may differ between halogen and HID-equipped cars, so it is important to match the bulb to the exact light location on your vehicle before ordering.

For the best fitment results, compare the bulb chart with your actual vehicle and confirm whether your A4 has halogen headlights or HID headlights, since several rear-light and brake-light applications differ between those setups. If you are converting to aftermarket LED bulbs, make sure the replacement is compatible with the vehicle’s electrical system and consider whether resistors or error-canceling features may be needed to avoid warning messages or hyperflash. Trim and lighting package differences can also change the bulb used in certain positions, so checking the installed bulb before purchase is the safest way to avoid returns and get the correct replacement the first time.
