Additional Notes

The Suzuki Motorcycle GSX-R600 uses the 12821 bulb for the license plate position across the 2011-2019 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts and rated at 5 watts.
The T10 designation refers to the bulb's tubular shape, with the number indicating a width of 10 millimeters expressed in eighths of an inch in the original American sizing convention.
The base type is W2.1x9.5d, a wedge-style base in which the glass envelope itself acts as the retention mechanism rather than a separate metal base, making it tool-free to remove and install.
Because the 12821 is a Philips-specific part number, equivalent bulbs from other manufacturers are identified by cross-referencing the T10 W2.1x9.5d base with a 12V, 5W rating rather than by the Philips number alone.
The consistent use of a single bulb specification across all nine listed model years indicates no fitment variation within that production span, meaning a single replacement unit covers the entire 2011-2019 range without compatibility concerns.
