BMW M3 2010 Bulb Size
Bulb size chart
This 2010 BMW M3 bulb size guide is designed to help you verify the correct bulbs by lighting position, so you can match the right part before you buy. Because BMW used different lighting setups by body style and market, the exact bulb list can vary, but this page organizes the common fitments for the 2010 M3 in a simple way.
Use the bulb chart to check exterior and interior locations one by one, including headlights, brake lights, turn signals, license plate lights, map lights, and cargo-area lighting. That makes it easier to narrow down the correct bulb for your 2010 BMW M3 Coupe or Sedan and avoid ordering the wrong replacement.
Fitment can change with trim level, lighting package, and body style, so always compare the bulb position on your car with the chart before purchasing. Some locations use LED assemblies or LED-style replacements, while others may use halogen bulbs such as H11, H16, H3, or D1S depending on the lamp. If you are considering an aftermarket LED conversion, make sure the bulb base, size, and beam pattern are compatible with the housing, and check whether your car needs a CAN-bus friendly bulb or resistor setup to prevent warnings. The safest approach is to inspect the installed bulb first, especially for rear lights and interior lamps where similar-looking bulbs can differ by application.
