Additional Notes

The Honda Motorcycle VTX1800F uses the 168 bulb for its license plate position across the 2005-2008 model years.
The 168 is an ANSI-standardized bulb type recognized across the United States and Canada, placing it within a regulated specification framework shared by many automotive and motorcycle applications.
This bulb follows the T10 miniature wedge form factor, a design that uses a tapered plastic base to seat directly into a wedge-style socket without a separate metal base or pins.
The 168 operates at 12 volts and draws 4.9 watts, classifying it as a low-wattage miniature bulb suited for small illumination tasks such as license plate lighting.
The T10 wedge base is a widely used form factor, and several bulb numbers share this physical base type. However, wattage and voltage ratings differ between them, meaning not all T10 wedge bulbs are electrically interchangeable with the 168 despite fitting the same socket.
