Additional Notes

The Lincoln Mark VIII uses the 168 bulb size across all listed model years, spanning 1993-1998.
The 168 bulb follows the ANSI standard, meaning it conforms to a recognized North American specification used in both the United States and Canada.
This bulb belongs to the T10 form factor, a miniature wedge-base type that does not use a separate metal base or pins, relying instead on the tapered plastic wedge of the bulb itself to make electrical contact within the socket.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
At 4.9 watts, the 168 is a low-wattage bulb, which is typical for license plate illumination where output requirements are modest.
Because the T10 wedge base is a widely shared form factor, multiple bulb part numbers beyond the 168 may physically fit the same socket, though electrical characteristics such as wattage and voltage ratings would need to match the original specification for proper function.
