Original BMW Center High-Mount Stop Light Gasket for BMW Z3 Roadster and M Roadster (1996–2001)

Z3 owners resealing the center high-mount stop light can use this Original BMW third brake light gasket on the Roadster and M Roadster. BMW names the part simply a gasket and places it in the Z3 lighting system. It weighs 4 grams and has been in BMW production since October 1995, ahead of the Z3's first model year, so the same number covers the car from launch. It is sold individually. A third brake light sits higher than the left and right brake lights so drivers behind see the stop signal sooner, and its gasket seals the lamp against the body.

Original BMW Parts carry a 24-month parts warranty.

BMW uses this one gasket across every Z3 engine it shows, including the M43 and M44 four-cylinders, the M52 and M54 sixes, and the S50, S52, and S54 M engines. That means a four-cylinder 1.9 Roadster and an S52 M Roadster share the part. A third brake light that fails to light, flickers, or lights dimly often points to a burned-out bulb, corroded connectors, faulty wiring, or a blown fuse.
