Additional Notes

The Yamaha WR250R uses the 168 bulb size for the license plate position across all listed model years from 2008-2019.
The 168 bulb is classified under the ANSI standard system, which is the standardized bulb coding used in the United States and Canada.
This bulb follows the T10 form factor, a miniature wedge-base design that seats without a twist-lock or bayonet mechanism, relying instead on tension from the socket housing to hold the bulb in place.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in most motorcycles.
The rated wattage of the 168 bulb is 4.9W, placing it in the low-power range typical of license plate and courtesy lighting applications.
The T10 wedge base is a widely used form factor, and multiple ANSI-coded bulbs share this physical base, meaning physical fitment alone does not confirm electrical compatibility with the WR250R specification.
