Additional Notes

The 168 bulb is the sole license plate bulb type listed for the Honda Motorcycle CH250 Elite across the 1989-1990 model years.
The 168 designation follows the ANSI standard used in the United States and Canada, classifying it as a miniature wedge bulb in the T10 form factor.
The T10 form factor refers to a tubular bulb with a wedge-style base, which seats directly into a socket without a separate metal base or pins.
The 168 bulb operates at 12 volts, consistent with the standard electrical system voltage found in most motorcycles of that era.
At 4.9 watts, the 168 bulb draws a low amount of power, which is typical for license plate lighting applications where output requirements are minimal.
The wedge base design of the T10 bulb means fitment depends on socket compatibility with that specific base type, and substituting a bulb with a different base style would not seat correctly in the factory socket.
