Additional Notes

The Kawasaki EN650 Vulcan S uses the 12961 bulb for the license plate position across the 2015-2020 model years.
The 12961 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 a tubular bulb with a width of 10 thirty-seconds of an inch, a common sizing standard in automotive and motorcycle lighting applications.
The base type is W2.1x9.5d, a wedge-style base where the electrical contacts are made through the glass pinch at the bottom of the bulb rather than through separate metal terminals.
The W2.1x9.5d base specification indicates a wedge width of 2.1mm and a pin spread of 9.5mm, which determines physical fitment into the socket.
Substituting a bulb with a different base type or voltage rating risks improper fitment or electrical incompatibility with the EN650 Vulcan S license plate socket.
