Additional Notes

The Kawasaki VN1700 Vulcan 1700 Classic uses the 12821 bulb for its license plate light across the 2009-2012 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which is one of the most widely used bulb types in automotive and motorcycle auxiliary lighting positions.
The bulb operates at 12 volts and draws 5 watts, a power rating typical of low-intensity indicator and auxiliary lighting applications rather than primary illumination.
The W2.1x9.5d base type is a wedge-style connection, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
T10 wedge bulbs with the W2.1x9.5d base are broadly interchangeable across many vehicle makes and models, which means LED retrofit options in the same base type are widely available as direct replacements.
