Audi Q3 2020 Bulb Size
Bulb size chart
This page covers bulb fitment for the 2020 Audi Q3 and is organized by lighting position so you can verify the correct bulb type before ordering. Because exterior and interior lighting can vary by trim, market, and package, matching the bulb location is the safest way to confirm what your vehicle uses.
On the 2020 Audi Q3, the available lighting positions on this page include LED-based headlight, tail light, brake light, turn signal, daytime running light, license plate light, reverse light, side marker, parking light, center high mount stop light, vanity mirror light, and optional stepwell light applications. Use the chart as a guide for replacement planning and cross-check the installed bulb or assembly before buying.
Fitment can differ between trims and lighting packages, especially on vehicles equipped with factory LED systems. Some 2020 Audi Q3 models may use complete LED modules rather than serviceable replaceable bulbs in certain positions, while other markets or body styles can have different configurations. If you are considering an aftermarket conversion, make sure the replacement is compatible with the vehicle’s electrical system and warning-canceling requirements. Before purchasing anything, inspect the bulb currently installed, compare the connector style and housing shape, and confirm the exact position on the vehicle so you do not order the wrong part.
