BMW M5 2018 Bulb Size
Bulb size chart
This 2018 BMW M5 bulb size page helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. The M5 uses LED lighting across the exterior and interior on the available bulb chart rows, which makes fitment easier to confirm once you know whether you are looking at the headlight, brake light, license plate light, or another location.
Use this guide as a quick reference for the 2018 BMW M5 when replacing a failed bulb or checking a lighting upgrade. Because bulb fitment can vary by position, market, trim, and body style, it is best to identify the exact lamp location first and then compare it with the chart for this page.
For the 2018 BMW M5, fitment can differ depending on trim, lighting package, and regional specification, so do not assume every car uses the same setup. Some vehicles may have factory LED assemblies where others in the same model family use different hardware, especially if there has been an aftermarket conversion or prior repair. Before ordering parts, check the installed bulb or lamp assembly on your car, compare the connector and housing style, and confirm whether you are replacing a complete LED module or a serviceable bulb position. This is especially important for headlight, fog light, and rear lamp applications, where halogen-to-LED swaps or non-OEM modifications can change what actually fits.
FAQ
Does the 2018 BMW M5 use LED bulbs for the headlights?
Yes. The available bulb chart for the 2018 BMW M5 lists the headlight high beam and low beam as LED. That means the headlight setup is not a standard replaceable halogen bulb in the usual sense, so you should verify the exact lamp assembly before ordering.
Are the fog lights on the 2018 BMW M5 LED?
Yes. The front fog light bulb position is listed as LED for this model year. If your car has a different setup, it may be due to market differences or a previous lighting modification.
What about the brake lights on the 2018 BMW M5?
The brake light bulb position is listed as LED. On many BMW applications, that means the light is part of an LED lamp assembly rather than a simple plug-in bulb.
Does the 2018 BMW M5 have LED turn signals?
Yes. Both the front turn signal light bulb and the rear turn signal light bulb are listed as LED on this page. Always check the exact side and lamp location before purchasing replacement parts.
Are the license plate lights LED on the 2018 BMW M5?
Yes. The license plate light bulb is listed as LED. This is a common exterior light that owners replace when they want to fix a warning, restore brightness, or match OEM appearance.
What bulb type is used for the daytime running lights?
The daytime running light bulb is listed as LED for the 2018 BMW M5. If the DRL is not working, you may need to inspect the full lamp assembly rather than just a removable bulb.
Are the reverse lights LED on this BMW M5?
Yes. The back up reverse light bulb is listed as LED. If one side is out, confirm whether the issue is the LED module, wiring, or the lamp housing itself.
Do interior lights on the 2018 M5 also use LED?
Yes. The available chart rows list the vanity mirror light, glove box light, trunk or cargo area light, dome light, map light, interior door light, and stepwell light as LED. Interior lighting can still vary by package, so check the installed part before ordering.
Is there a difference between the side marker lights front and rear?
Yes. The front side marker light bulb and rear side marker light bulb are both listed as LED, but they are separate positions and may not use the same exact lamp hardware. Match the location carefully.
Can I replace an LED bulb on the 2018 BMW M5 with an aftermarket LED conversion?
Sometimes, but it depends on the lamp position and the original design. Some lights are integrated LED assemblies, while others may accept a serviceable bulb or an aftermarket conversion. Check for fit, polarity, warning messages, and heat management before installing anything non-OEM.
Why should I check the installed bulb before buying a replacement?
Because trim, lighting package, market, and body style can change the exact fitment. Checking the installed bulb or lamp assembly helps you avoid ordering the wrong part, especially on a premium car like the 2018 BMW M5 where many lights are LED-based.
What is the best way to use this page for bulb replacement?
Start by identifying the exact lighting position, such as headlight, fog light, brake light, or license plate light. Then compare that position with the chart on this page to confirm the 2018 BMW M5 bulb type before you purchase or install a replacement.
