Additional Notes

The Kawasaki VN1700 Vulcan 1700 Voyager uses the 12821 bulb for its license plate position across the 2009-2020 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts and rated at 5 watts.
The T10 designation refers to the bulb's tubular envelope, with the number indicating a width of 10 millimeters, a standard sizing convention used across the automotive and motorcycle lighting industry.
The W2.1x9.5d base type is a wedge-style connector, meaning the bulb is held in place by the tension of its socket rather than by a bayonet or screw mechanism.
At 5 watts, the 12821 falls within the low-wattage range typical of license plate and courtesy lighting applications, where output requirements are minimal compared to headlamp or signal positions.
The W2.1x9.5d base specification is a precise fitment standard, and substituting a bulb with a physically incompatible base type would result in an improper fit regardless of voltage or wattage compatibility.
