Additional Notes

The Yamaha YZF-R6 uses the 168 bulb size for the license plate position across the 2003-2020 model years.
The 168 bulb is a miniature wedge type, classified under the T10 form factor, which refers to a tubular bulb with a 10mm width.
This bulb operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The 168 designation follows ANSI standardization, meaning it conforms to a defined set of electrical and physical specifications recognized across the United States and Canada.
The wedge base design of the T10 eliminates the need for a separate metal base or bayonet pins, as the glass envelope itself acts as the retention mechanism within the socket.
Because the 168 is an ANSI-standardized wedge bulb, it is physically interchangeable with other T10 wedge bulbs that share the same base configuration, though electrical ratings should be matched to the original specification.
The consistent use of the 168 bulb across all 18 listed model years indicates a stable socket and housing design in the license plate lighting assembly throughout that production span.
