Additional Notes

The Ducati Monster 620 uses the 12961 bulb for its license plate light across the 2002-2006 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 uses a W2.1x9.5d base, which is the standard wedge-type base common to many small automotive lighting applications.
The bulb operates at 12 volts and draws 5 watts, placing it in the low-power range typical of license plate and courtesy lighting.
Because the same bulb size applies uniformly across all five model years listed, the 12961 is a consistent fitment for the Monster 620 throughout its production run in those years.
The W2.1x9.5d base is not compatible with bayonet or festoon-style sockets, so substitutions must match the wedge base type to fit correctly.
