Additional Notes

The P21/5W is the tail light bulb type specified for the Kawasaki KVF650 Prairie across the 2002-2003 model years.
The P21/5W is an ECE-standard dual-filament bulb rated at 12 volts, with filaments drawing 21 watts and 5 watts respectively, where the higher-wattage filament typically serves the brake light function and the lower-wattage filament serves the running light function.
The P21/5W uses a BAY15d bayonet base, which is an offset twin-pin fitting. The pin offset is a deliberate design feature that prevents incorrect insertion, meaning a bulb with a standard symmetric BAY15d base cannot be seated in the wrong orientation.
The ECE designation indicates the bulb conforms to United Nations Economic Commission for Europe regulations, a standard recognized across European and many international markets.
