This 2016 Audi Q3 bulb size guide helps you verify the correct bulb by lighting position, so you can match the right part before you buy. Because the Q3 can use different lighting setups depending on trim, market, and body style, checking the exact lamp location is the safest way to avoid ordering the wrong replacement.
Use this page as a quick reference for exterior and interior bulbs on the 2016 Audi Q3. It covers common items like headlights, brake lights, turn signals, license plate lights, cargo lights, and cabin bulbs, with notes for LED-equipped models and other package-specific variations.
Fitment can vary between halogen and LED headlight packages, and some front signal or headlight bulb listings change based on the factory lighting system. That means a bulb that fits one 2016 Q3 may not fit another, even if the vehicles look similar. If you are considering an aftermarket conversion, compare the original bulb type, connector style, and housing design before buying. The best practice is to check the bulb already installed in your vehicle, confirm the part number or base type, and then purchase a replacement that matches the exact application.
