The Mercury Villager side marker requires bulb size 194 or 194NA depending on the specific version of the component. Data for the lighting components covers the range from 1995 to 2002.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercury Villager uses the 194 bulb for its front side marker across all listed model years, spanning 1993-2002.
The 194 bulb is an ANSI-standardized 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 without a separate locking mechanism, relying instead on the tension of the socket housing to hold it in place.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of marker and courtesy lighting applications.
The rear side marker on the Mercury Villager also takes the 194 bulb, covering model years 1993-1998.
Because both the front and rear side marker positions share the same 194 bulb specification, a single bulb type serves both locations on applicable model years.
The T10 wedge base is a widely produced form factor, and the 194 designation specifically identifies a particular wattage and voltage rating within that family, meaning not all T10 bulbs are interchangeable with the 194 despite sharing the same base style.
