Additional Notes

The INFINITI QX56 uses the 168 bulb size for the license plate position across all listed model years, spanning 2004-2013.
The 168 bulb is classified under the ANSI standard, which is the recognized specification system for automotive bulbs in the United States and Canada.
It belongs to the T10 miniature wedge form factor, a design that uses a tapered plastic base to friction-fit directly into a socket without requiring a separate metal base or locking mechanism.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Its rated power draw is 4.9 watts, placing it in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The wedge base construction of the 168 means fitment depends on the physical taper of the base rather than a bayonet or screw interface, so substitutions must match the T10 wedge profile to seat correctly in the socket.
