Additional Notes

The Lincoln LS uses the 168 bulb size for the map light across all model years in the specification, spanning 2000-2006.
The 168 bulb is an ANSI-standardized type, meaning its electrical and physical characteristics conform to a defined North American specification recognized in both the United States and Canada.
This bulb follows the T10 miniature wedge form factor, a design in which the base of the bulb itself acts as the connector by wedging directly into the socket without a separate metal base or pins.
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 heat management are relevant factors.
Because the T10 wedge base is a widely shared form factor, various bulbs carrying different ANSI numbers may physically fit the same socket, though voltage and wattage ratings must match the original specification to avoid electrical issues.
