Audi R8 2021 Bulb Size
Bulb size chart
This 2021 Audi R8 bulb guide helps you verify the correct bulb type by lighting position, so you can match the right replacement to the right lamp. Because the R8 uses LED lighting in many areas, the exact fit can depend on the specific lamp location, trim, and market.
Use this page as a quick reference for exterior and interior bulb fitment on the 2021 Audi R8. Whether you are checking the headlight, tail light, license plate light, or cabin lighting, the goal is to make it easier to confirm what belongs where before you buy parts.
Fitment can vary on the 2021 Audi R8 depending on trim, lighting package, body style, and regional equipment. Some positions are LED from the factory, while others may differ if the car has been modified or converted with aftermarket parts. If your R8 has had any lighting repairs, retrofits, or non-OEM upgrades, the safest approach is to inspect the installed bulb or module before ordering a replacement. That is especially important when comparing halogen-style replacement listings to factory LED assemblies, since many LED units are not simple bulb swaps and may require the complete lamp or a specific module instead of a loose bulb.
