Additional Notes

The Aprilia Scarabeo 100 uses the 12961 bulb for the license plate position across the 2006-2011 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor.
T10 refers to the bulb's tubular shape, with the number indicating a width of 10 millimeters.
The 12961 operates on 12 volts and draws 5 watts, which is a low-power rating typical of small auxiliary lighting positions such as license plate 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 W2.1x9.5d base designation is standardized, meaning the 12961 is interchangeable with other T10 wedge bulbs sharing that same base specification, provided the voltage and wattage ratings are compatible with the socket.
