The 2015 Audi Q3 uses a mix of LED and halogen-style bulb applications depending on the lamp position, and some items may vary by market, trim, or lighting package. Use this page as a quick reference for common bulb locations such as headlights, brake lights, license plate lights, reverse lights, fog lights, and cabin bulbs on the 2015 Audi Q3.
Fitment can change with trim level, package content, and body style, so it is smart to confirm the bulb already installed in your vehicle before placing an order.
