Additional Notes

The Suzuki Motorcycle GSX1300R Hayabusa uses the 12821 bulb for the license plate position across the 2008-2009 and 2011-2019 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which refers to the tubular glass envelope with a 10mm width.
The bulb operates on 12 volts with a 5-watt output, a rating typical of low-draw indicator and auxiliary lighting positions on motorcycles.
The W2.1x9.5d base type is a wedge-style connector, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
The W2.1x9.5d designation specifies a wire width of 2.1mm and a pin spread of 9.5mm, which determines physical socket compatibility.
The 12821 specification remains consistent across all listed model years, indicating no variation in the license plate bulb fitment throughout the documented production span.
T10 wedge bulbs in this voltage and wattage class are widely used in auxiliary positions across many vehicle types, though socket fitment depends on the specific W2.1x9.5d base dimension matching the housing.
