Additional Notes

The Honda Motorcycle VTX1800N uses the 168 bulb for the license plate position across all listed model years, spanning 2004-2008.
The 168 is an ANSI-standardized bulb type recognized across the United States and Canada, meaning it conforms to a defined set of electrical and physical characteristics shared by compliant manufacturers.
The 168 bulb is a miniature wedge type, designated T10, which refers to its tubular glass envelope with a width of 10 millimeters. The wedge base design means the bulb is held in its socket by the tension of the base itself rather than by a separate bayonet or screw mechanism.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The T10 wedge format is widely shared among miniature automotive bulbs, which means certain other bulb numbers in the same family may physically fit the VTX1800N license plate socket. However, electrical compatibility depends on matching voltage and wattage ratings to avoid socket or circuit issues.
