Audi S5 2021 Bulb Size
Bulb size chart
This page helps you verify the bulb sizes for the 2021 Audi S5 by lighting position, so you can match the correct bulb to each exterior and interior location before ordering. Because Audi used LED lighting across most of the car, the fitment list is organized by function rather than by a single universal bulb type.
For the 2021 Audi S5, many forward and rear lighting points are LED from the factory, including the low beam, high beam, daytime running light, brake light, tail light, and turn signals. That makes it especially important to check the exact lighting position on your car, since trim level, body style, and market can affect the final setup.
Fitment can vary by trim, lighting package, and region, so always compare this page with the bulbs already installed in your vehicle before buying replacements. The 2021 Audi S5 is heavily LED-equipped, but some owners may still encounter differences when swapping parts or adding aftermarket conversions. If you are changing from halogen to LED or replacing an LED module, confirm connector style, housing design, and any error-free compatibility needs before purchase. When possible, inspect the original bulb or module first, especially for items like the glove box light, where the listed bulb type is 2821.
