Additional Notes

The Kawasaki KLR650 uses the 12821 bulb for the license plate position across all listed model years from 2008-2018.
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 shape, with the number indicating a width of 10 millimeters.
The base type is W2.1x9.5d, a wedge-style base that relies on tension from the socket rather than a bayonet or screw mechanism to maintain contact.
At 5 watts, the 12821 is a low-power bulb suited to small illumination tasks such as license plate lighting rather than high-output applications.
The W2.1x9.5d base is a standardized wedge fitting, meaning functionally equivalent bulbs from other manufacturers sharing this base type are generally interchangeable with the 12821 provided the voltage and wattage ratings match.
