Additional Notes

The Kawasaki KVF750 Brute Force uses the P21/5W bulb type for the brake light position across all model years covered in the specifications, spanning 2005-2022.
The P21/5W is a dual-filament bulb, with the 21W filament serving the brighter brake or stop function and the 5W filament serving a lower-intensity running light function within the same housing.
The P21/5W operates on a 12V electrical system, which is consistent with standard 12-volt vehicle wiring.
This bulb type uses a BAY15d bayonet base, which features two offset pins at different heights to ensure the bulb is seated in only one rotational orientation, preventing the filaments from being wired to the wrong circuit.
The P21/5W conforms to ECE regulations, a standard recognized across Europe and numerous other markets worldwide, meaning the bulb meets defined output and safety requirements for signalling applications.
Because the BAY15d base is offset-pin, it is not interchangeable with the BA15d base, which carries identically spaced pins. Substituting a BA15d bulb in a BAY15d socket would result in incorrect fitment or reversed filament function.
