Additional Notes

The Aprilia RSV 1000 R uses the 12961 bulb for the license plate position across the 2005-2009 model years.
The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12 volts and 5 watts.
The T10 designation refers to a tubular bulb body approximately 10mm wide, a common form factor in motorcycle auxiliary lighting positions.
The W2.1x9.5d base is a wedge-type fitting, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
At 5 watts, the 12961 is a low-power bulb typical of license plate and courtesy lighting applications, where output requirements are minimal.
The W2.1x9.5d base is standardized, so the 12961 is interchangeable with other T10 wedge bulbs sharing that base type, provided the voltage and wattage ratings are compatible with the socket.
