Additional Notes

The Piaggio Fly 50 uses the 12961 bulb for the license plate position across all specified model years from 2007-2019.
The 12961 is a Philips part number designation for a miniature wedge-style bulb.
This bulb follows the T10 form factor, which refers to a tubular bulb with a 10mm body width.
The base type is W2.1x9.5d, a wedge base where the electrical contacts are formed by the glass envelope itself rather than a separate metal cap.
The 12961 operates at 12 volts, consistent with the standard electrical system voltage found on most small-displacement scooters.
The rated wattage of 5W places this bulb in the low-power category typical of license plate illumination applications.
The T10 wedge format is a widely produced bulb type, meaning the 12961 specification is shared with a broad range of other vehicle applications beyond the Fly 50.
Because the W2.1x9.5d wedge base is a standardized interface, aftermarket and OEM-equivalent bulbs from manufacturers other than Philips may fit the same socket, provided they match the T10 form factor and 12V/5W ratings.
