This page for the 2016 Audi S3 helps you verify bulb sizes by lighting position, so you can match the correct replacement before ordering. Because Audi used different lighting packages and market-specific setups, the bulb type can vary depending on whether your car has LED or HID headlights and on the exact trim.
Use the bulb chart on this page as a position-by-position reference for exterior and interior lights. It covers common replacement points such as the low beam, high beam, brake lights, license plate lights, turn signals, reverse lights, cabin lights, and more, making it easier to identify the right bulb for your 2016 Audi S3.
For best fitment, always compare your car’s trim, lighting package, and body style with the chart before buying. A 2016 Audi S3 with LED headlights may use different front turn signal or headlight bulb listings than a car with HID headlights, and some markets may have different equipment from the factory. If you are considering an aftermarket LED or HID conversion, make sure the bulb base, connector, and beam pattern are compatible with your housing, and remember that a conversion does not always match factory performance. The safest approach is to check the installed bulb or the existing lamp assembly before purchase, especially for interior bulbs and any exterior light that can vary by package.
