BMW M3 2004 Bulb Size
Bulb size chart
This page covers the 2004 BMW M3 and helps you verify bulb sizes by lighting position, so you can match the correct bulb to the exact lamp on the car. Because the M3 uses different bulbs for exterior, interior, and cargo-area lighting, checking the position first is the easiest way to avoid ordering the wrong part.
Use the bulb chart for the 2004 BMW M3 as a fitment guide for headlights, turn signals, brake lights, reverse lights, license plate lights, dome lights, and other locations. Trim and lighting equipment can vary, so the same model year may use different bulbs depending on body style and market.
For best results, compare the bulb listed on this page with the one already installed in your car before buying replacements. Some 2004 BMW M3s may have trim or package differences, and lighting setups can change with halogen versus LED upgrades or aftermarket conversions. If your car has been modified, especially in the headlight or interior lighting areas, the original bulb size may no longer match the current setup. Checking the old bulb, connector, and housing style first can save time and prevent fitment issues.
