Additional Notes

The 168 bulb is the sole license plate bulb size listed for the Yamaha YW50F Zuma 50F across all model years in the specifications, spanning 2012-2019.
The 168 is classified as a miniature wedge bulb, designated by the T10 designation, which refers to its tubular wedge-base form factor measuring 10 millimeters in width.
The wedge base design means the bulb is held in place by tension from the socket itself rather than by a separate bayonet or screw mechanism, which is a common trait in small automotive and powersports lighting applications.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of license plate and courtesy lighting positions.
The 168 designation follows ANSI standardization, meaning it conforms to a defined set of electrical and physical parameters recognized across the United States and Canada.
Because the 168 is an ANSI-standardized T10 wedge bulb, it shares its base type with several other bulb numbers in the same family, though substitutions across different ANSI numbers are not confirmed as interchangeable by the specifications provided.
