This 2015 Audi S3 bulb size page helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. Because the S3 can use different lighting setups depending on trim, market, and package, checking the exact bulb location is the safest way to avoid ordering the wrong replacement.
Use this guide to identify the bulb type for exterior and interior lights on the 2015 Audi S3, including headlights, brake lights, license plate lights, turn signals, and cabin bulbs. The chart is organized by function, which makes it easier to compare your car’s current setup with the listed fitment.
Fitment can vary on the 2015 Audi S3 depending on body style, lighting package, and whether the car has halogen, HID, or LED equipment from the factory. Some positions may use LED modules instead of replaceable bulbs, while others can differ between markets or option packages. If you are upgrading to aftermarket LED replacements or converting from halogen to LED, check for bulb warnings, polarity issues, and beam pattern changes. Before placing an order, it is always smart to inspect the installed bulb or confirm the part number from the vehicle itself, since the same model year can have more than one valid bulb type for a given light position.
