The Lincoln Mark VI uses 194 bulb size for both front and rear side marker applications. The replacement chart covers 1980 to 1983 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Lincoln Mark VI uses the 194 bulb for both front and rear side markers across its full production span of 1980-1983.
The 194 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The 194 bulb follows the T10 miniature wedge form factor, which uses a tapering plastic base that presses directly into a socket without a separate metal base or locking mechanism.
At 12 volts and 3.78 watts, the 194 is a low-wattage bulb suited to always-on marker lamp applications rather than high-intensity signaling functions.
Because the front and rear side marker positions on the Lincoln Mark VI share the same 194 bulb, a single bulb type serves all four side marker sockets on the vehicle.
The T10 wedge base is a widely used form factor, and a number of bulbs from other manufacturers carry the same 194 designation, provided they conform to the ANSI standard's voltage and wattage ratings.
Substituting a wedge bulb of a different wattage rating into a socket designed for the 194 risks improper illumination levels and potential heat incompatibility with the original socket housing.
