Original BMW Left Side Marker Light for BMW M3 (2015–2018) and M4 (2015–2020)

Sold as a single left-hand piece, this Original BMW side marker light fits the F80 M3 sedan and the F82 and F83 M4 from 2015–2020, marking the left flank of the car. BMW's name for it is the left side marker light, under part number 63-14-7-848-581. It weighs only 35 g (1.23 oz), a small part that shares one number across the M3 sedan, the M4 coupe, and the M4 convertible. BMW shows production starting in March 2014.

The part is covered by a 24-month parts warranty as an Original BMW Part.

A side marker light is a small amber or clear reflector light on the side of the car near a front or rear corner. It makes the car visible from the side at night and in low light. This number is the left-hand marker only, so the right side needs its own part. BMW's data carries the same left marker through the facelift versions of the F80, F82, and F83, as well as the M4 GTS and M4 CS. A pre-facelift and a late-production car therefore take the same piece. That makes ordering simple: confirm the side and the chassis, and the S55-powered variants all match.

Common Questions

Is this the same marker for the M3 and the M4?
Yes. BMW uses this one left-side part number on the F80 M3, the F82 M4 coupe, and the F83 M4 convertible, including facelift cars.

When should a side marker light be replaced?
Replace it when the lens is cracked or broken. Damage lets moisture and dirt in, which can corrode the contacts and wiring, and fogging inside the lens points to a failed seal.

Does the GTS or CS take a different marker?
No. BMW lists the M4 GTS and M4 CS under the same part number as the standard M4.
