BMW M5 2008 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 2008 BMW M5 by lighting position, so you can match the correct replacement before you buy. Because trim, market, and body style can change the lighting setup, checking the exact lamp location is the safest way to avoid ordering the wrong bulb.
For the 2008 BMW M5, the listed bulb chart covers exterior and interior positions such as the headlight, brake light, turn signals, reverse light, license plate light, dome light, map light, glove box light, trunk light, and courtesy lights. Use the position name first, then confirm the bulb type shown for that spot on your car.
Fitment can vary on this M5 depending on trim package, lighting equipment, and whether the car has factory xenon or LED-related components. Some positions are listed as LED, while others use specific halogen or incandescent bulb types, so do not assume every light on the car uses the same technology. If your car has been modified with aftermarket conversions, the installed bulb may differ from the original factory listing. Before purchasing, it is a good idea to remove the old bulb and compare the base, connector, and markings to the bulb chart so you can confirm the correct replacement.
