Additional Notes

The Kawasaki EX650 Ninja 650 uses the 12961 bulb for the license plate position across the 2012-2022 model years, making it a consistent fitment throughout that entire production span.
The 12961 is a Philips part number designating a T10 miniature wedge bulb, a form factor widely used in low-intensity automotive lighting applications such as license plate and courtesy illumination.
The bulb operates at 12 volts and 5 watts, which reflects the low power draw typical of license plate lighting, where output requirements are minimal compared to forward-facing or signal lighting.
The T10 designation refers to the bulb's tubular envelope, with the base type specified as W2.1x9.5d, a wedge-style base that relies on spring tension within the socket rather than a bayonet or screw mechanism for retention.
The W2.1x9.5d base is a standardized wedge base, meaning the 12961 may be interchangeable with other T10 wedge bulbs sharing the same base type, voltage, and wattage rating, provided the physical envelope fits the housing.
