Additional Notes

The INFINITI Q70L uses the 168 bulb size for the license plate position across all listed model years, spanning 2015-2019.
The 168 bulb is classified under the ANSI standard, which is the recognized specification system used in the United States and Canada for automotive lighting components.
This bulb follows the T10 form factor, a miniature wedge-base design that seats without a separate socket lock, relying instead on the tension of the wedge base itself to maintain contact.
The 168 operates at 12 volts, which is consistent with the standard electrical system voltage found in passenger vehicles.
At 4.9 watts, the 168 draws a low amount of power, a characteristic typical of license plate and other auxiliary lighting positions.
The T10 wedge base is a widely produced form factor, and the 168 shares physical compatibility with several other bulb numbers in the same family, such as the 194 and 161, though those alternatives carry different wattage ratings that may affect circuit load.
Because the 168 and its T10 relatives differ in wattage, substituting a higher-wattage variant in the Q70L license plate socket could exceed the designed load for that circuit.
