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

The Hyosung GV250 Aquila uses the 12961 bulb for its parking light across all listed model years from 2005 to 2015.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor.
T10 refers to the bulb's tubular shape, with the number indicating a width of 10 thirty-seconds of an inch, making it a small-profile bulb commonly found in parking and interior lighting applications.
The 12961 uses a W2.1x9.5d base, which is the standard wedge-type base where the bulb's plastic wedge body itself acts as the retaining mechanism rather than a separate metal contact pin.
The electrical rating of the 12961 is 12 volts and 5 watts, consistent with low-draw parking light duty on a 12-volt vehicle electrical system.
Because the W2.1x9.5d base is a wedge type, fitment depends on the socket cavity accepting the specific wedge body width, and substitutions with physically different wedge sizes may not seat correctly even if the voltage and wattage ratings match.
