Additional Notes

The Triumph Rocket III Touring uses the 12961 bulb for its license plate light across the 2012-2014 and 2016-2017 model years.
The 12961 is a Philips part number designating a T10 miniature wedge bulb, a format widely used in low-current automotive lighting positions such as license plate and courtesy lamps.
The bulb operates at 12 volts and draws 5 watts, placing it in the low-wattage range typical of indicator and auxiliary lighting rather than primary illumination.
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.
The T10 designation refers to the bulb's tubular envelope width of 10 millimeters, a standard sizing used across many automotive applications, which means physically similar T10 bulbs from other manufacturers may share the same socket fitment.
Because the 12961 is a Philips-specific part number, equivalent bulbs from other manufacturers are cross-referenced by their T10 form factor and W2.1x9.5d base rather than by the Philips number alone.
