Additional Notes

The Ford Crown Victoria uses the 168 bulb for the map light across all listed model years from 1992 to 2011.
The 168 is an ANSI-standardized bulb, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
It belongs to the T10 form factor, which refers to a miniature wedge-base bulb roughly 10 thirty-seconds of an inch in width at its widest point.
The wedge base design means the bulb is held in place by the socket gripping the glass envelope directly, with no separate metal base or pins involved.
The 168 operates at 12 volts, which is consistent with standard automotive electrical systems.
At 4.9 watts, the 168 is a low-wattage bulb, typical of interior courtesy and reading light applications where prolonged use and low heat output are relevant factors.
The T10 wedge format is shared by several bulb numbers in the same family, including the 194 and 192, though those carry different wattage ratings and are not interchangeable without accounting for those differences.
