Additional Notes

The 921 is the sole brake bulb size listed for the Polaris 600 XC across all years in the specifications, covering 1996-1999 and 2003.
The 921 bulb follows the ANSI standard, which is the recognized specification system used in the United States and Canada for automotive and powersports lighting components.
It uses a wedge base, designated T15, which refers to a tubular bulb body approximately 15 eighths of an inch wide. The wedge base design requires no separate metal socket pins, as the glass envelope itself forms the electrical contact when inserted.
The 921 operates at 12 volts and draws 16 watts, placing it in the range typical of single-filament stop and tail lighting applications.
Because the 921 uses a wedge base rather than a bayonet or screw base, it is not interchangeable with bulbs of differing base types even if voltage and wattage ratings are similar.
