Additional Notes

The 168 bulb is the license plate bulb size for the Lexus LX470 across all listed model years, spanning 1998-2007.
The 168 bulb follows the ANSI standard recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across North American markets.
It belongs to the T10 miniature wedge bulb family, a form factor characterized by a wedge-shaped base that holds the bulb in place without a separate metal socket pin.
The 168 operates at 12 volts, which is consistent with the standard electrical system voltage found in passenger vehicles.
Its rated power output is 4.9 watts, placing it in the low-wattage range typical of license plate and courtesy lighting applications.
The T10 wedge base type is shared by several bulb numbers in the same family, including the 194 and 2825, which carry different wattage ratings and are not direct equivalents of the 168 despite the shared base style.
Because wattage differs between T10 variants, substituting a higher-wattage T10 bulb in a socket rated for the 168 risks exceeding the thermal tolerance of the license plate housing.
