Additional Notes

The Kawasaki ZR900 Z900 uses the 12961 bulb for its license plate position across the 2017-2019 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base.
The T10 designation refers to a tubular bulb with a width of 10 millimeters, commonly found in low-intensity automotive lighting positions such as license plate and parking lights.
The W2.1x9.5d base is a wedge-type base, meaning the bulb is held in place by the tension of the socket rather than by a bayonet or screw mechanism.
The 12961 operates at 12 volts and 5 watts, placing it in the low-wattage range typical of auxiliary and marker lighting applications.
The consistent use of a single bulb specification across all three listed model years indicates that the license plate housing design remained unchanged throughout the 2017-2019 production period.
