Additional Notes

The INFINITI FX50 uses the 168 bulb size for the license plate position across the 2009-2013 model years.
The 168 is a T10 miniature wedge bulb, a form factor that requires no socket rotation for installation, as the wedge base seats directly into a friction-fit holder.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of license plate lighting applications.
The 168 carries ANSI standardization, meaning its electrical and physical characteristics conform to a defined specification recognized in both the United States and Canada.
The T10 designation refers to the bulb's tubular envelope width, expressed in eighths of an inch, making the glass envelope approximately 10/8 of an inch wide.
Because the 168 is an ANSI-standardized wedge type, it shares physical compatibility with several other bulb numbers in the T10 wedge family, though wattage differences among those alternatives can affect circuit load and brightness.
