Additional Notes

The KTM 350 EXC-F uses the T10 miniature wedge bulb across its 2012-2016 model years for the license plate position.
The T10 designation refers to a tubular bulb with a 10mm body width, commonly found in low-current auxiliary lighting positions such as license plate, parking, and courtesy lamp applications.
The W2.1x9.5d base is a wedge-type connector, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
The 12961 is a Philips part number, and it corresponds to a 12-volt, 5-watt output rating, which is standard for license plate illumination on motorcycles and light vehicles.
At 5 watts on a 12-volt circuit, the bulb draws approximately 0.42 amperes, consistent with the low electrical load typical of auxiliary lighting circuits on off-road competition motorcycles.
The W2.1x9.5d base type is not universally interchangeable with all T10-sized bulbs, as some T10 bulbs use different base configurations, making base type a relevant factor when sourcing a replacement.
