Additional Notes

The Plymouth Caravelle uses the 168 bulb for the license plate position across the 1985-1988 model years.
The 168 bulb follows the ANSI standard, meaning it conforms to a specification recognized in both the United States and Canada.
This bulb belongs to the T10 form factor, which is a miniature wedge-base type. The wedge base design means the glass envelope itself acts as the retention mechanism, with no separate metal base or pins involved.
The 168 bulb operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
At 4.9 watts, the 168 bulb draws a relatively low amount of power, which is typical for a license plate application where output requirements are modest.
The T10 wedge format is widely used across many vehicle makes and models, which contributes to broad retail availability of the 168 bulb.
Because the 168 designation is an ANSI-standardized part, bulbs carrying this number from different manufacturers are expected to share the same electrical and physical specifications, supporting interchangeability within that standard.
