Additional Notes

The KTM 990 Super Duke uses the 12961 bulb for its license plate light across the 2005-2011 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 uses a W2.1x9.5d wedge base, which is a pinless base type that is held in place by the tension of the socket itself rather than by pins or a bayonet lock.
The bulb operates at 12 volts and draws 5 watts, placing it in the low-wattage category typical of auxiliary and indicator lighting applications.
The T10 wedge format is one of the most widely produced miniature bulb types, and the W2.1x9.5d base is its standardized socket interface across many vehicle manufacturers.
Because the 12961 is a Philips-branded part number, equivalent bulbs from other manufacturers are cross-referenced by their base type and electrical rating rather than by this specific number.
The W2.1x9.5d base designation is shared by a range of T10 bulbs with varying wattages, so wattage confirmation is relevant when substituting one T10 bulb for another in this application.
