Additional Notes

The Suzuki Motorcycle GSX1300R Hayabusa uses the 12961 bulb for its parking light across the 2008-2019 model years covered in these specifications.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which refers to the tubular glass envelope with a width of 10 millimeters.
This bulb uses a W2.1x9.5d wedge base, a baseless design where the glass envelope itself forms the contact points, eliminating the need for a separate metal base.
The electrical rating of the 12961 is 12 volts and 5 watts, placing it in the low-wattage category typical of parking and position light applications.
Because the 12961 is a Philips-branded part number rather than a universal industry code, equivalent bulbs from other manufacturers are cross-referenced under different part numbers despite sharing the same T10 form factor and W2.1x9.5d base.
The T10 wedge format is widely used in motorcycle position lighting due to its compact size and tool-free installation, as the bulb is retained by socket tension alone.
