The American Motors AMX front and rear side marker bulbs both utilize a 194 bulb size. The replacement chart covers 1970 through 1980 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 194 bulb is the sole bulb type specified for the American Motors AMX across all listed side marker positions and model years.
The 194 bulb conforms to the ANSI standard recognized in both the United States and Canada, classifying it as a regulated, standardized automotive lamp.
It is a miniature wedge-type bulb, designated T10, which refers to its tubular glass envelope width of 10 eighths of an inch.
The wedge base design means the bulb is held in its socket by the shape of its glass base rather than by metal pins, eliminating the need for a separate bayonet or screw fitting.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage category typical of marker and clearance lamp applications.
Both the front and rear side marker positions on the AMX share the same 194 bulb specification across the years 1970 and 1978-1980, meaning a single bulb type serves all four side marker sockets on the vehicle.
Because the front and rear side marker sockets accept the same bulb, the 194 is interchangeable between those positions on the AMX without modification.
The T10 wedge format is a widely produced size, and aftermarket variants including LED replacements are commonly manufactured to the same base specification, though electrical compatibility with the original AMX circuitry is a separate consideration.
