Additional Notes

The Honda Motorcycle GL1800 Gold Wing uses the 168 bulb size for its license plate light across all listed model years from 2001 to 2017, with the exception of 2011, which is not present in the specifications.
The 168 bulb is a miniature wedge type, classified under the T10 form factor, which refers to a tubular bulb with a wedge base rather than a traditional screw or bayonet mount.
This bulb operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of license plate and courtesy lighting applications.
The 168 designation follows the ANSI standardization system, meaning it is a recognized specification used across the United States and Canada rather than a proprietary or manufacturer-specific part number.
Because the 168 is an ANSI-standardized T10 wedge bulb, it is physically interchangeable with other bulbs sharing the same wedge base and T10 form factor, provided voltage and wattage ratings are compatible with the socket.
The T10 wedge base design means the bulb is retained in its socket by the tension of the base contacts alone, without any locking mechanism, which is a common trait of license plate bulb housings on motorcycles.
The consistent use of the 168 bulb across the 2001-2017 GL1800 Gold Wing model range indicates that the license plate light socket specification did not change during this production period.
