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

The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, fitted with a W2.1x9.5d base. It operates at 12 volts and draws 5 watts, placing it in the low-wattage range typical of parking and marker lighting applications.
The W2.1x9.5d base is a wedge-type connection, meaning the bulb is retained by tension from the socket walls rather than by a bayonet or screw mechanism. This base type is not interchangeable with bayonet or festoon sockets.
The Polaris Slingshot uses the 12961 bulb for the front side marker position across the 2018-2019 model years.
