Audi S4 2002 Bulb Size
Bulb size chart
The 2002 Audi S4 uses a mix of bulb types across the exterior and interior, and the exact fit can vary by market, trim, lighting package, and body style. This page is designed to help you verify the correct bulb size by lighting position, so you can match the right replacement before you buy.
Whether you are replacing a low beam headlight, a license plate lamp, a fog light, or an interior map light, checking the bulb location first makes the job much easier. Use this 2002 Audi S4 bulb guide to compare the listed positions with the bulbs already installed on your car.
Fitment can differ between sedan and Avant models, and some cars may have different bulbs depending on factory options or previous repairs. The same is true for halogen versus LED upgrades and aftermarket conversion kits, which can change the bulb type needed or require additional adapters. Before ordering, inspect the bulb currently in the vehicle and compare it with the chart, especially for fog lights, daytime running lights, and headlight conversions. If your S4 has been modified, the installed bulb may not match the original factory specification, so a quick visual check can save time and returns.
