Additional Notes

The 168 bulb is the license plate bulb size for the Lexus HS250h across the 2010-2012 model years.
The 168 bulb follows the ANSI standard, which is the recognized specification framework used in the United States and Canada for automotive lighting components.
This bulb uses a T10 miniature wedge base, a small single-contact base type that is retained by friction rather than a twist-lock or bayonet mechanism.
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 format is shared across a wide range of vehicle makes and models, though fitment to a specific socket position depends on the housing design of each individual vehicle.
