Additional Notes

The Kawasaki ZX1400 Ninja ZX-14R uses the 12821 bulb for its license plate position across the 2012-2014 and 2019 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which refers to a tubular bulb approximately 10/32 of an inch wide.
This bulb operates on a 12-volt electrical system and draws 5 watts, placing it in the low-wattage category typical of auxiliary lighting positions such as license plate illumination.
The W2.1x9.5d base type is a wedge-style connector, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
The T10 wedge format is widely used across many vehicle manufacturers, which means the 12821 is not an exclusive or proprietary fitment to this motorcycle.
Despite broad cross-compatibility of the T10 wedge format in general, fitment should be confirmed against the specific socket housing of the ZX1400 Ninja ZX-14R, as physical clearance around the license plate assembly can vary.
