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.
The T10 designation refers to the bulb's tubular shape, with the number indicating a width of ten-eighths of an inch. The W2.1x9.5d base is a wedge-type connection, meaning the bulb is held and makes electrical contact through tension rather than a separate metal connector.
The Hyosung MS3-250 uses the 12961 bulb for the parking light position across the 2008-2009 model years.
The W2.1x9.5d base type is a standardized wedge fitting, and bulbs sharing this base specification from other manufacturers are generally interchangeable with the 12961, provided the voltage and wattage ratings match.
At 5 watts and 12 volts, the 12961 draws approximately 0.42 amperes, which is consistent with a low-current parking or position light application rather than a primary illumination function.
