The Lincoln Mark VII uses 194 bulb size for both front and rear side marker applications. The replacement chart covers vehicle production spanning 1984 to 1992.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Lincoln Mark VII uses the 194 bulb for both front and rear side marker positions across the 1984-1992 model years.
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.
This bulb follows the T10 form factor, a miniature wedge-base design that seats by friction rather than by a bayonet or screw mechanism.
The 194 bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
At 3.78 watts, the 194 draws relatively low power, which is typical for side marker applications where continuous illumination is required without significant electrical load.
Because the front and rear side marker positions share the same bulb size on the Lincoln Mark VII, a single bulb type services both locations on the vehicle.
The T10 wedge base is a widely produced form factor, and the 194 designation is shared across many vehicle makes and models, reflecting broad interchangeability within this bulb family.
Substitution with other T10-based bulbs carrying different wattage ratings may affect circuit load and could conflict with the vehicle's original electrical tolerances.
