Additional Notes

The Lincoln Town Car uses two bulb sizes for the license plate position across its production span: the 168 and the 194, both of which are ANSI-standardized miniature wedge bulbs of the T10 type operating at 12 volts.
Although the 168 and 194 share the same T10 wedge form factor and voltage rating, they are not electrically identical. The 168 draws 4.9 watts while the 194 draws 3.78 watts, making them distinct specifications despite their physical similarity.
The 168 bulb is the more widely used of the two across the Lincoln Town Car's license plate fitment history, appearing in the 1981-1989, 1992-1993, and 1998-2011 model years.
The 194 bulb is specified for the 1990-1991, 1994-1997 model years.
The 1992 and 1993 model years use the 168, while the immediately surrounding years of 1990-1991 and 1994 use the 194, indicating that the same generation of vehicle did not necessarily retain a single bulb specification throughout its production run.
Because the 168 and 194 share the T10 wedge base, physical installation of either into the other's socket is possible, though doing so would result in a wattage mismatch relative to the original specification.
