This page for the 2005 Audi A4 helps you verify the correct bulb size by lighting position, so you can match the right lamp to the right socket before you buy. Because the A4 was offered in different body styles and lighting packages, the exact bulb can change between the sedan, Avant wagon, and Cabriolet, as well as between halogen and HID headlight setups.
Use the bulb chart to narrow down the fitment for exterior lights, interior lights, and cargo-area lamps. Whether you are replacing a license plate bulb, a rear turn signal, a low beam, or a dome light, checking the location first is the easiest way to avoid ordering the wrong part for your 2005 Audi A4.
Fitment can vary by trim, market, and package, so always compare the bulb position on your car with the chart before purchasing. Headlight and fog light options may differ between halogen and LED-style replacements, and some aftermarket conversions are not direct plug-and-play swaps even when the base bulb size looks similar. If your A4 has been modified, or if you are unsure whether it uses a standard incandescent bulb, HID capsule, or LED upgrade, remove the installed bulb and confirm the marking on the base before ordering. That quick check is especially helpful for exterior lamps where the same model year may use different bulbs across body styles.
Start with the light position, such as low beam, rear turn signal, license plate, or dome light. Then match that position to the bulb size listed for your body style and lighting package. This is the safest way to confirm fitment on a 2005 Audi A4.
No. The bulb size can change depending on whether your car is a Base sedan, Avant wagon, or Cabriolet, and whether it has halogen or HID headlights. Trim and market differences can also affect fitment.

Yes. The Avant uses different rear lamp bulbs in some positions, including 7528 for the brake light, tail light, and rear side marker. The Base sedan and Cabriolet use different rear bulb listings, so check the exact body style before ordering.
Confirm the exact light position, body style, and headlight type, then compare the installed bulb number if possible. This is the best way to avoid ordering the wrong bulb, especially for headlights, fog lights, and rear lamps.
