Additional Notes

The 168 bulb is the license plate bulb size for the Chrysler Aspen across its 2007-2009 model years.
The 168 bulb follows the ANSI standard, which is the American National Standards Institute classification used in the United States and Canada to define bulb performance and dimensional specifications.
It is a T10 miniature wedge-base bulb, a form factor that uses a plastic wedge at its base to make direct contact with the socket without a separate metal connector.
The 168 operates at 12 volts, consistent with standard automotive electrical systems.
Its rated wattage is 4.9W, placing it in the low-power range typical of license plate and courtesy lighting applications.
The wedge base design of the T10 means fitment depends on socket compatibility with that specific base type, and substitution with bulbs using different base types would not be interchangeable.
