Additional Notes

The Kawasaki ZX1400 Ninja ZX-14R ABS uses the 12821 bulb for the license plate position across the 2013-2020 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which refers to a tubular bulge approximately 10 millimeters wide at its widest point.
The bulb operates on a 12-volt electrical system and draws 5 watts, placing it in the low-wattage range 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 the tension of the socket rather than by a bayonet or screw mechanism.
T10 wedge bulbs with the W2.1x9.5d base are a widely standardized format, and the 12821 designation confirms fitment within that standard for this application.
Because the 12821 is a manufacturer-specific part number from Philips, cross-referencing with equivalent T10 5W wedge bulbs from other manufacturers requires confirming that the W2.1x9.5d base specification is matched exactly to avoid fitment issues.
