Additional Notes

The Kawasaki VN1700 Vulcan 1700 Voyager uses the P21/5W bulb for its parking light across all model years from 2009 to 2020.
The P21/5W is a dual-filament bulb, meaning it contains two separate filaments within a single glass envelope, one rated at 21 watts and the other at 5 watts.
The higher 21-watt filament typically serves the brighter stop or turn signal function, while the lower 5-watt filament handles the dimmer parking or tail light function.
The P21/5W operates on a 12-volt electrical system, which is standard for motorcycle applications.
This bulb uses a BAY15d bayonet base, which features two offset pins positioned at different heights on the base to ensure correct orientation during installation and prevent the filaments from being connected to the wrong circuit.
The P21/5W is an ECE-regulated bulb type, meaning it conforms to standards recognized across Europe and many other international markets.
The BAY15d base is not interchangeable with the BAY15s single-contact bayonet base, as the dual-contact design is specific to dual-filament applications and the pin offsets differ between the two types.
