Ford Pinto front and rear side marker bulbs both utilize a 194 bulb size across all production variants. The replacement chart covers 1971 to 1980 model 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 Ford Pinto uses the 194 bulb for both the front and rear side markers across all model years covered in the specifications, spanning 1971-1980.
The 194 is an ANSI-standardized bulb type, meaning its physical and electrical characteristics conform to a defined industry specification recognized in both the United States and Canada.
This bulb belongs to the T10 miniature wedge form factor, which uses a wedge-shaped base rather than a pin or bayonet mount, allowing it to seat directly into a compatible socket without a separate metal base.
The 194 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 Ford Pinto (1971-1980) uses the same 194 bulb in all four side marker positions, front and rear replacements draw from the same bulb type, simplifying parts sourcing.
The T10 wedge base format of the 194 is a widely produced size, and any replacement must match the T10 wedge specification to seat correctly in the Pinto's side marker sockets.
Voltage compatibility is a critical fitment consideration; substituting a bulb rated for a different voltage than 12V in these positions risks either insufficient output or premature failure.
