Additional Notes

The KTM 990 Supermoto uses the 12961 bulb for the license plate position across the 2008-2013 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 the bulb's tubular form factor, which is among the most widely used miniature bulb types in automotive lighting applications.
The W2.1x9.5d base is a wedge-style base, meaning the bulb is held in its socket by the tension of the glass envelope itself rather than by a separate metal cap or bayonet fitting.
At 5 watts, the 12961 is a low-power bulb consistent with the modest illumination requirements of a license plate light.
The 12-volt operating voltage is standard for motorcycle electrical systems, making the 12961 broadly compatible with the 990 Supermoto's electrical architecture.
Because the 12961 is a Philips-branded part number, equivalent bulbs from other manufacturers must share the same T10 form factor, W2.1x9.5d base, 12V rating, and 5W rating to serve as a direct fitment replacement.
