Additional Notes

The Mercury Lynx uses the 168 bulb for its license plate light across all listed model years, spanning 1981-1987.
The 168 is an ANSI-standardized bulb type recognized in both the United States and Canada.
It belongs to the T10 form factor, a miniature wedge-base design that does not require a separate socket twist-lock mechanism, as the wedge base itself secures the bulb by friction.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage of 4.9W places it in the low-power range typical of auxiliary lighting functions such as license plate illumination.
The T10 wedge base is shared by several bulb numbers in the same family, meaning physical fitment alone does not confirm electrical equivalence with other T10-based bulbs.
