Additional Notes

The Hyosung ST7 uses the 12961 bulb for its parking light across the 2010-2015 model years.
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 millimeters.
The 12961 uses a W2.1x9.5d base, which is the standard wedge-type base common to small automotive parking and interior bulbs.
The bulb operates at 12 volts and draws 5 watts, placing it in the low-wattage range typical of parking light applications.
Because the W2.1x9.5d base is a wedge type, the bulb is held in place by friction rather than a bayonet or screw mechanism.
Any replacement bulb intended for the ST7 parking light position must match the T10 form factor and W2.1x9.5d base to seat correctly in the socket.
Substituting a bulb with a higher wattage rating than 5W risks exceeding the thermal tolerance of the socket and surrounding housing.
