Additional Notes

The Hyosung GT650 uses the 12961 bulb for its license plate light across all listed model years, spanning 2010-2017.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, rated at 12 volts and 5 watts.
The T10 designation refers to a tubular bulb with a width of 10 millimeters, a format widely used in low-intensity automotive lighting positions such as license plate, parking, and interior applications.
The W2.1x9.5d base type is a wedge-style connector, meaning the bulb is held in place by the tension of the socket rather than by a bayonet or screw fitting.
At 5 watts, the 12961 operates at a low power draw, consistent with its role as an indicator or illumination bulb rather than a primary lighting source.
The consistent use of a single bulb specification across eight consecutive model years indicates a stable socket and electrical configuration throughout the GT650's listed production run.
Wedge-base bulbs such as the T10 W2.1x9.5d are not interchangeable with bayonet-base or festoon-style bulbs, as the base geometry and retention method differ fundamentally between those types.
