Additional Notes

The 168 bulb is the license plate bulb size for the INFINITI Q50 across the 2014-2016 and 2018 model years.
The 168 bulb follows the ANSI standard, which is the recognized specification body for miniature automotive bulbs in the United States and Canada.
It is a T10 miniature wedge-base bulb, meaning it uses a wedge-shaped base rather than a bayonet or screw fitting, and seats directly into a wedge-type socket without a separate metal base.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of license plate and courtesy lighting applications.
The T10 wedge form factor is shared by several bulb numbers in the miniature wedge family, so fitment depends on matching both the base type and the specific electrical rating rather than the base shape alone.
