Additional Notes

The Honda Motorcycle Grom 125 uses the 168 bulb size for its license plate light across all listed model years.
The 168 bulb follows the ANSI standard, which is the recognized classification system for bulbs in the United States and Canada.
It belongs to the T10 form factor, a miniature wedge-base bulb that seats by friction fit rather than a twist-lock or bayonet mechanism.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in most motorcycles.
At 4.9 watts, the 168 produces a relatively low power draw, which is typical for license plate lighting applications.
The T10 wedge base is a widely produced form factor, meaning the 168 is broadly available as both an incandescent unit and in LED retrofit versions that share the same base type.
Model years 2014-2015 and 2017-2020 all share the same 168 bulb fitment, meaning no bulb change is required when sourcing a replacement across those years.
