Additional Notes

The Plymouth TC3 uses the 168 bulb for its license plate light across the 1980-1982 model years.
The 168 bulb follows the ANSI standard, meaning it conforms to a specification recognized across the United States and Canada.
It is a miniature wedge-base bulb, classified under the T10 designation, which refers to its tubular shape measured in eighths of an inch.
The wedge base design means the bulb is held in place by the socket gripping its glass base directly, with no separate metal base or pins involved.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of that era.
At 4.9 watts, the 168 draws a low amount of power, which is typical for a license plate application where illumination requirements are minimal.
