Audi RS 7 2015 Bulb Size
Bulb size chart
The 2015 Audi RS 7 is a high-performance liftback with a premium lighting setup, and the exact bulb used can vary by lighting position. This page is designed to help you verify bulb sizes by location so you can match the correct replacement for the back up reverse light, glove box light, trunk or cargo area light, and interior door light.
Because the RS 7 may differ by market, trim, and lighting package, it is important to confirm the bulb size for each socket before ordering. Use the bulb chart on this page as a quick reference for the 2015 Audi RS 7, and compare it with the bulb already installed in your vehicle when possible.
Fitment on the 2015 Audi RS 7 can change with trim, package content, and whether the car uses halogen or LED lighting in a given position. That matters especially for interior and cargo-area lamps, and it can also affect whether a simple bulb swap is possible or whether a complete LED module is used. Aftermarket LED conversions may fit physically but still differ in brightness, color, or warning behavior, so it is smart to check the installed bulb and the original housing before buying. If your RS 7 has been modified or repaired, verify the socket style and bulb type at the car rather than relying only on model-year listings.
