Additional Notes

The Honda Motorcycle GL1500I Gold Wing Interstate uses the 168 bulb size for the license plate position across the 1992-1996 model years.
The 168 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across those markets.
The 168 bulb is a miniature wedge type, designated T10, which refers to its tubular glass envelope with a width of 10 millimeters and a wedge-shaped base that seats directly into a socket without a separate metal base or pins.
The wedge base design means the filament leads themselves form the electrical contacts, a construction that distinguishes it from bayonet or festoon bulb types sometimes found in other license plate applications.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in motorcycles of this class and era.
At 4.9 watts, the 168 draws a low amount of power, which is typical for license plate illumination, a position that requires only enough output to meet visibility regulations rather than functional lighting demands.
The T10 wedge form factor is shared by several bulb numbers, including the 194 and 147, though those variants differ in wattage and are not direct substitutes for the 168 without confirming socket and circuit compatibility.
