Additional Notes

The Plymouth Volare uses the 168 bulb for its license plate position across the 1976-1980 model years.
The 168 bulb is an ANSI-standardized type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
It belongs to the T10 miniature wedge family, a form factor defined by a wedge-shaped base that connects directly into a socket without a separate metal cap or pins.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
Its rated power draw is 4.9 watts, placing it in the low-wattage range typical of auxiliary lighting positions such as license plate illumination.
The wedge base design of the 168 means fitment depends on socket compatibility with the T10 form factor, and substitution with pin-base or bayonet-base bulbs of similar wattage would not be physically interchangeable.
