Additional Notes

The Lincoln Navigator uses the 168 bulb for its license plate position across all model years from 1998 to 2018.
The 168 is classified as a miniature wedge bulb, operating on 12 volts with a power draw of 4.9 watts.
The T10 designation refers to the bulb's wedge base type, which is a common format in automotive lighting where the base itself acts as the electrical contact without a separate metal connector.
The 168 bulb conforms to ANSI standards recognized in both the United States and Canada, indicating a standardized specification for electrical and physical properties.
The T10 wedge format is shared across a wide range of automotive applications, which means the 168 is interchangeable with other bulbs of the same base type, provided the wattage and voltage ratings are also matched.
At 4.9 watts, the 168 is a low-wattage bulb, consistent with the minimal illumination demands of a license plate light position.
The uninterrupted use of the 168 across all 21 model years in the specifications reflects a stable socket and housing design throughout the Navigator's production during that period.
