Original BMW Third Brake Light Lens for BMW Z3 Roadster and M Roadster (1996–2001)

BMW's third brake light lens, part number 63-25-8-389-733, is the lens for the center high-mount stop light on the 1996–2001 BMW Z3 Roadster and M Roadster. A center high-mount stop light is the brake light mounted above the left and right brake lights. Its job is to give drivers behind a clearer warning when the brakes are applied. BMW calls this part simply "Lens" and gives its weight as 53 g (0.1 lb). BMW sells it by the piece, and its production record starts in October 1995.

Original BMW Parts carry a 24-month parts warranty.

The same lens appears under a second OE number, 63-12-8-389-733. If your parts book or an old invoice shows that number, this is the same part. Within the Z3 range, BMW assigns this one lens to every engine: the four-cylinder M43 and M44, the six-cylinder M52 and M54, and the S50, S52, and S54 engines in the M Roadster. You do not need to match the lens to engine size or trim.

Common Questions

Does the same lens fit the M Roadster?
Yes. BMW applies this lens to the M Roadster with the S50, S52, and S54 engines, as well as to the standard Z3 Roadster.

Is the bulb or the housing included?
BMW lists this part simply as "Lens". The packet does not list a bulb or housing with it, so send us your VIN if you want help confirming what you need.

Why do I see two different part numbers for it?
63-12-8-389-733 is an alternate OE number for this same lens.

A clean, genuine lens keeps the Z3's high-mount brake light as visible as it was from the factory.
