This 2016 BMW M4 bulb size page helps you verify the correct bulbs by lighting position, so you can match the right fit before you buy. The M4 can use different lighting setups depending on market, trim, and factory options, so checking the exact lamp location is the safest way to confirm replacement bulbs.
For this model year, many exterior and interior lights are LED from the factory, while a few positions still use specific bulb types. Use this page to compare headlights, turn signals, reverse lights, brake lights, and cabin bulbs for the 2016 BMW M4 and avoid guessing based on a single bulb type.
Fitment can vary by trim package, lighting package, body style, and whether the car has factory LED or HID equipment. Some positions may look similar but use different bulb types, and aftermarket LED conversions can change the required size or connector style. If your M4 has been modified, or if a previous owner changed the lighting, it is smart to check the installed bulb before ordering replacements. That is especially important for headlight and turn signal applications, where halogen, HID, and LED setups may not share the same bulb specification.
