BMW Motorcycle R60/7 front and rear turn signal bulbs utilize a P21W size across all applications. The replacement chart covers 1976 to 1980 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The BMW Motorcycle R60/7 uses the P21W bulb type for both its front and rear turn signals across all listed model years, 1976-1980.
The P21W is a single-filament bulb, meaning it serves one lighting function only, which is consistent with its dedicated use in turn signal applications.
The P21W operates at 12 volts and 21 watts, placing it within the standard range for automotive turn signal applications worldwide.
The P21W uses a BA15s bayonet base, a single-contact bayonet fitting where the "s" denotes a single pin offset to one side, which prevents incorrect installation orientation.
The P21W conforms to ECE (Economic Commission for Europe) standards, indicating it meets regulated performance and safety requirements recognized across Europe and many other markets globally.
The front and rear turn signal positions on the R60/7 share the same P21W specification across all listed years, meaning a single bulb type covers all four turn signal sockets on the motorcycle.
Because the BA15s base is a keyed single-contact fitting, it is not directly interchangeable with the BA15d base, which carries two offset pins for dual-filament bulbs.
