BMW M3 2018 Bulb Size
Bulb size chart
The 2018 BMW M3 uses different bulb types depending on the lighting package, body style, and market, so this page is designed to help you verify bulb sizes by lighting position. Use the chart to match the correct bulb for each location before you buy replacement parts.
For the 2018 BMW M3, many exterior lighting functions are LED, while some versions with HID headlights use different bulbs for the front signals and headlamps. Checking the bulb by position is the easiest way to avoid ordering the wrong fitment.
Fitment can vary between trims and packages, especially on cars with LED headlights versus HID headlights, and between adaptive and non-adaptive lighting setups. If your M3 has been converted with aftermarket lighting parts, the bulb type may no longer match the factory listing, so it is smart to confirm what is installed before purchasing. When possible, inspect the existing bulb, connector, and housing style first, since even the same year and model can use different parts depending on equipment. This is especially important for front turn signals, headlamps, and brake light applications where LED and HID configurations differ.
