Additional Notes

The Ducati Monster 1000 uses the 12961 bulb for its license plate light across the 2003-2005 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 a small tubular bulb widely used in low-intensity automotive lighting positions such as license plate, courtesy, and instrument panel applications.
The W2.1x9.5d base designation refers to a wedge-type connection where the bulb's glass envelope itself acts as the retention mechanism, requiring no separate metal base or locking collar.
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 12V operating voltage aligns with the standard electrical system voltage found on conventional motorcycle platforms, including the Ducati Monster 1000.
T10 wedge bulbs are produced by multiple manufacturers under various part numbers, and the 12961 designation is specific to Philips; equivalent bulbs from other brands must share the same T10 wedge form, W2.1x9.5d base, 12V rating, and 5W rating to be considered interchangeable.
