Philips part number. Miniature wedge bulb (T10) with W2.1x9.5d base. 12V, 5W.	12961	Check Price

The T10 miniature wedge bulb is the parking light type used across the Kawasaki ZR650 Z650 for the 2017-2018 model years, operating at 12 volts and rated at 5 watts.
The T10 designation refers to a tubular bulb with a 10mm body width, and the W2.1x9.5d base is a wedge-style fitting where the base width is 2.1mm and the pin spacing is 9.5mm.
The specific part number referenced in the specifications is 12961, which is a Philips catalog number for this T10 wedge bulb configuration.
The W2.1x9.5d wedge base is a push-in, pinless design, meaning the bulb is retained by friction from the socket walls rather than by a bayonet or screw mechanism.
At 5 watts on a 12-volt circuit, the bulb draws approximately 0.42 amperes, which is consistent with low-current indicator and parking light applications.
