Mercury Bobcat front and rear side marker bulbs utilize a 194 bulb size across both positions. The replacement chart covers vehicle production spanning 1975 to 1980.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 194 bulb is the sole bulb type specified across all front and rear side marker positions on the Mercury Bobcat.
The 194 bulb conforms to the ANSI standard recognized in both the United States and Canada, placing it within a widely adopted North American specification framework.
It is a miniature wedge type, classified under the T10 form factor, which refers to a tubular bulb with a wedge base that seats directly into a socket without a separate metal base or pins.
The 194 bulb operates at 12 volts with a power draw of 3.78 watts, consistent with standard low-current automotive marker light applications.
The front side marker position on the Mercury Bobcat uses the 194 bulb across the full 1975-1980 model year range covered in the specifications.
The rear side marker position uses the same 194 bulb, with coverage spanning the 1977-1980 model years as listed in the specifications.
The shared 194 fitment across both front and rear side marker positions means a single bulb type serves all specified marker sockets on the vehicle.
The T10 wedge base format is a friction-fit design, meaning the bulb is retained in its socket by the tension of the base rather than by a bayonet lock or screw mechanism.
