This 2020 BMW M4 bulb size page helps you verify the correct bulb type by lighting position, so you can match the right part before you buy. Whether you are replacing an exterior lamp or a small interior light, the goal is to make fitment easier and reduce guesswork for your specific M4.
The 2020 BMW M4 uses LED lighting for many exterior and interior positions, but the exact setup can still vary by market, trim, and body style. Use this page as a position-by-position reference for common bulb locations such as headlights, tail lights, turn signals, license plate lights, and cabin lights.
For best results, compare the bulb chart with your actual vehicle before ordering, especially if your M4 has a different lighting package, regional equipment, or an aftermarket retrofit. Some cars may have factory LED assemblies where the bulb is not serviced separately, while other positions may still use replaceable bulbs like the glove box light or vanity mirror light. If your car has been converted from halogen to LED, or if a previous owner changed parts, the installed bulb may not match the original catalog listing. Always inspect the old bulb, connector, and housing before purchase so you can confirm fitment and avoid returns.
FAQ
What does this 2020 BMW M4 bulb page help me check?
It helps you verify bulb sizes and lighting types by location, such as low beam, high beam, fog light, brake light, license plate light, and interior lamps. That makes it easier to match the correct replacement for the exact position on the car.
Are the headlights on the 2020 BMW M4 LED?
Yes, the bulb chart for this page lists both the low beam and high beam headlight positions as LED. In many cases, that means the light source is part of an LED assembly rather than a simple replaceable halogen bulb.
Can I replace the fog light bulb on a 2020 BMW M4 with the same type listed here?
The front fog light position is listed as LED on this page. If your car uses the factory LED setup, the replacement may be an LED module or assembly rather than a traditional bulb, so confirm the exact housing before ordering.
What bulb does the glove box light use on a 2020 BMW M4?
The glove box light is listed as 2825, 98. That is one of the few positions on this page with a specific bulb reference instead of only LED.
What bulb does the vanity mirror light use on a 2020 BMW M4?
The vanity mirror light is listed as 2723. As with other small interior lamps, it is a good idea to compare the installed bulb before buying a replacement.
Do all 2020 BMW M4 trim levels use the same bulbs?
Not always. Trim, lighting package, market, and body style can change the exact fitment. This is especially true for exterior LED assemblies and interior convenience lights.
Are the brake lights and tail lights on the 2020 BMW M4 LED?
Yes, the bulb chart lists the brake light and tail light positions as LED. That usually means the rear lighting is integrated and may not use a standard removable bulb for every function.
What should I check before buying a replacement bulb for my M4?
Check the lighting position, the bulb base or module style, and the connector shape. It also helps to inspect the old bulb or assembly, because previous repairs or aftermarket parts can change what is installed.
Can I use aftermarket LED bulbs in positions that were originally halogen?
Only if the housing, connector, and electrical system are compatible. On a 2020 BMW M4, many listed positions are already LED, but any aftermarket conversion should be checked carefully for fitment, warnings, and beam pattern.
Why does this page list some lights as LED instead of a bulb number?
Because many 2020 BMW M4 lighting positions use LED modules or integrated assemblies rather than a standard service bulb. In those cases, the correct replacement is often the complete unit or module, not a generic bulb.
How do I know if my 2020 BMW M4 has the same bulb setup as the chart?
Use the chart as a guide, then confirm with your vehicle identification, build details, and the installed part. The same year and model can still differ by region or equipment package, so a quick visual check is the safest way to confirm fitment.
Is it safe to replace interior bulbs myself on a 2020 BMW M4?
For simple interior positions like the glove box, vanity mirror, dome, map, trunk, or door lights, replacement is often straightforward if the bulb is serviceable. Just make sure the ignition is off and the part matches the installed bulb before you start.
