BMW M3 2001 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 2001 BMW M3 by lighting position, so you can match the correct bulb to the correct socket before you buy. Because fitment can differ by market, trim, and body style, it is best to use the bulb chart below as a position-by-position reference rather than assuming every lamp uses the same part.
For the 2001 BMW M3, the chart includes exterior bulbs such as the low beam headlight, turn signals, brake lights, reverse lights, parking lights, side markers, and license plate lights, along with interior bulbs for the dome, map, glove box, vanity mirror, trunk, and courtesy areas. Using the correct location matters, since several bulbs share similar sizes but are not interchangeable in every lamp assembly.
Before ordering, compare the bulb listed for your exact lighting position with the bulb already installed in the car, especially if your M3 has different trim, a lighting package, or market-specific equipment. Some owners may also encounter halogen-to-LED changes or other aftermarket conversions, and those can alter fitment, color, and warning behavior. If the car has been modified, always check the installed bulb and connector style first, then confirm the replacement matches both the socket and the intended use.
FAQ
What bulb does the 2001 BMW M3 use for the low beam headlight?
The listed low beam headlight bulb is D2S. This is one of the most important fitment checks on the page because the headlight system is not the same as the smaller exterior signal bulbs.
What is the rear turn signal bulb size on the 2001 BMW M3?
The rear turn signal light bulb is 7507. The same bulb size is also listed for the front inner turn signal position.
What bulb fits the front inner turn signal on this M3?
The front inner turn signal light bulb is 7507. If your car has a different lamp setup due to market or body-style differences, confirm the installed bulb before buying.
What is the front outer turn signal bulb size?
The front outer turn signal light bulb is 2827. This is separate from the front inner turn signal bulb, so the two front signal positions should be checked individually.
Which bulb is used for the front parking light and front side marker?
Both the parking light bulb and the front side marker light bulb are listed as 2825, 98. These positions use the same bulb size on this page.
What bulb does the reverse light use?
The back up reverse light bulb is 7506. If one reverse lamp is out, it is a good idea to replace both sides together for even brightness.
What bulb is listed for the brake light?
The brake light bulb is 7506R. Because brake and tail functions can be easy to confuse, it is worth checking the exact lamp position before ordering.
What bulb size is used for the tail light and rear side marker?
The tail light bulb is 7225, and the rear side marker light bulb is also 7225. That means both rear positions on this page share the same bulb size.
What bulb does the license plate light use?
The license plate light bulb is 6418. This same bulb size is also listed for several interior lights, so make sure you are replacing the correct location.
Which interior bulbs are listed for the dome, glove box, and map lights?
The dome light bulb, glove box light bulb, stepwell light bulb, and several courtesy light positions are listed as 6418, while the map light bulb and rear reading light bulb are listed as 6486X. These interior locations are not all the same, so check the specific lamp before purchase.
What bulb is used for the vanity mirror and trunk/cargo area lights?
The vanity mirror light bulb and trunk or cargo area light are listed as 6411, 6428. The page also shows courtesy light options that may use the same bulb family depending on the original setup.
Why does the page mention different courtesy light options?
The 2001 BMW M3 can have different courtesy light fitments depending on trim, package, or market. The page lists multiple courtesy light options so you can compare the position on your car with the bulb size that matches your original lamp.
Can I switch my M3 bulbs to LED replacements?
Yes, but fitment and function should be checked carefully. LED replacements can change brightness, beam pattern, and warning behavior, so confirm that the bulb matches the socket and works correctly in the intended position.
What should I check before ordering bulbs for this year and model?
Check the exact bulb position, compare the installed bulb to the chart, and confirm whether your car has original equipment or an aftermarket conversion. This is especially important on the 2001 BMW M3 because trim and lighting package differences can affect fitment.
