Additional Notes

The Aprilia Mana 850 uses the 12961 bulb for the license plate position across the 2008-2012 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 form factor is one of the most widely used bulb types in small automotive and motorcycle lighting positions, particularly for license plate, courtesy, and instrument lighting applications.
The W2.1x9.5d base designation refers to a wedge-style base with a 2.1mm wire contact width and a 9.5mm insertion depth, which determines physical fitment into the socket.
At 5 watts, the 12961 operates at a low power draw, consistent with its role as an auxiliary lighting bulb rather than a primary illumination source.
The wedge base design of the T10 means the bulb is held in place by tension from the socket walls rather than by a bayonet or screw mechanism, which affects how it is seated and removed.
Because the 12961 is a manufacturer-specific part number from Philips, equivalent bulbs from other manufacturers must share the same T10 form factor, W2.1x9.5d base, 12V rating, and 5W rating to be considered interchangeable.
