Additional Notes

The Kawasaki VN1700 Vulcan 1700 Vaquero uses the 12821 bulb for its license plate position across the 2011-2020 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base.
The T10 designation refers to a tubular bulb with a width of 10 millimeters, a common sizing standard in automotive and motorcycle lighting applications.
The W2.1x9.5d base specification describes a wedge-type connection where the bulb is held in place by tension rather than a bayonet or screw fitting, with a pin spacing of 9.5 millimeters.
The 12821 operates at 12 volts and 5 watts, placing it in the low-wattage range typical of license plate and courtesy lighting positions.
The single bulb specification across all ten listed model years indicates no fitment variation within this range, meaning a 12821 sourced for any one of those years is interchangeable with the others.
