Additional Notes

The Ford Granada used the 168 bulb for its license plate lighting across all listed model years, spanning 1977-1982.
The 168 bulb follows the ANSI standard, which is the recognized specification body governing bulb designations in the United States and Canada.
It belongs to the T10 form factor, a miniature wedge-base bulb that connects without a separate metal base, relying instead on the tapered plastic wedge of its base to seat directly into the socket.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this type.
Its rated wattage of 4.9W places it in the low-power range, which is typical for license plate applications where illumination requirements are modest.
The T10 wedge base is shared across numerous bulb part numbers, meaning physical fitment alone does not confirm electrical compatibility; voltage and wattage ratings require separate verification before substitution.
