Additional Notes

The T10 miniature wedge bulb, designated by Philips part number 12961, is the license plate bulb type used in the Vespa 946 for the 2013-2014 model years.
The 12961 operates at 12 volts and consumes 5 watts, which is standard for low-load license plate illumination in passenger vehicles and scooters.
The W2.1x9.5d base designation describes the wedge-style base of the T10 bulb, where the two figures refer to the width and pin spacing of the wedge contact, ensuring a friction-fit connection without a separate locking mechanism.
The T10 designation refers to the bulb's tubular envelope size, with the numeral indicating a width of roughly 10 millimeters, a common form factor across many license plate and interior lighting applications.
Because the 12961 is a Philips-branded part number, equivalent T10 W2.1x9.5d bulbs from other manufacturers are generally interchangeable provided they match the 12V, 5W electrical rating and the W2.1x9.5d base specification.
