Additional Notes

The Lexus ES350 uses the 168 bulb size for the license plate position across the 2007-2012 model years.
The 168 bulb is classified as a miniature wedge type, designated T10, which refers to its wedge-shaped base that allows it to be inserted directly into a socket without a separate metal base or pins.
It 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 168 designation follows the ANSI standardization system, meaning it meets defined electrical and physical specifications recognized across the United States and Canada.
Because the 168 is an ANSI-standardized T10 wedge bulb, it shares its base type with several other bulb numbers in the same family, though wattage and voltage ratings can differ between them, making direct substitution a matter of matching all three specifications rather than base type alone.
