This page helps you verify the bulb sizes for the 2009 Audi R8 by lighting position, so you can match the correct bulb to the correct socket before you buy. Because the R8 could be equipped with different lighting setups, it is important to check the exact function on the vehicle, not just the model name.
For the 2009 Audi R8, many exterior lighting positions use LED components, while some interior and utility lights use standard bulb sizes such as 2825, 98, 6418, 5200, or 64136. Use the chart on this page to compare headlight, tail light, brake light, turn signal, side marker, license plate, and cargo-area bulb fitment in one place.
Fitment can vary by trim, lighting package, body style, and market, so always confirm whether your 2009 R8 has halogen, HID, or LED headlights before ordering. Some positions also change with aftermarket conversions, especially when owners retrofit LED or HID systems. The safest approach is to inspect the installed bulb or housing label first, then compare it with the bulb chart before purchase. That extra check helps avoid buying the wrong base, wattage, or connector style.
