Additional Notes

The Honda Motorcycle CBR500R uses the 168 bulb size for its license plate light across the 2013-2020 model years.
The 168 is a miniature wedge-type bulb, classified under the T10 form factor, which refers to its tubular shape with a width of 10 millimeters.
The wedge base design means the bulb is held in place by tension from the socket itself rather than by a separate metal base or locking mechanism.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of auxiliary lighting functions such as license plate illumination.
The 168 designation follows ANSI standardization, meaning it conforms to a defined set of electrical and physical specifications recognized across the United States and Canada.
Because the 168 is an ANSI-standardized T10 wedge bulb, it shares physical and electrical compatibility with several other bulbs in the same family, such as the 194 and 147, though wattage differences between these types can affect brightness and socket load.
The T10 wedge format is widely used in automotive and motorcycle applications for low-intensity positions, making replacement units broadly available across the aftermarket.
