Additional Notes

The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, fitted with a W2.1x9.5d base. It operates at 12 volts and draws 5 watts.
The W2.1x9.5d base is a wedge-type connection, meaning the bulb is held in place by tension from the socket rather than by a locking collar or bayonet pins.
The T10 designation refers to the tubular bulb body, with the number indicating a width of 10 eighths of an inch. This is one of the most widely used form factors in automotive auxiliary lighting applications.
The Yamaha MT-09 (2020-2021) uses the 12961 bulb for the license plate position.
At 5 watts, the 12961 is a low-power bulb, consistent with its role in a non-safety-critical illumination position such as a license plate lamp.
The W2.1x9.5d base type is shared across a broad range of T10 wedge bulbs from multiple manufacturers, which means aftermarket equivalents from other brands are generally interchangeable with the 12961 provided the voltage and wattage ratings match.
