Additional Notes

The Yamaha YZF-R3 uses the 168 bulb size for its license plate light across the 2015-2020 model years.
The 168 bulb follows the ANSI standard recognized in the United States and Canada, classifying it as a regionally standardized automotive component.
It belongs to the T10 miniature wedge form factor, a base type that requires no locking mechanism and is seated by the tension of its wedge-shaped base within the socket.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in most motorcycles and passenger vehicles.
Its rated power draw is 4.9 watts, placing it in the low-wattage category typical of auxiliary lighting functions such as license plate illumination.
The T10 wedge base is a widely used form factor, meaning 168-type bulbs are broadly interchangeable with other T10-compatible sockets, provided voltage and wattage ratings are also compatible.
