American Motors Pacer front and rear side marker bulbs both utilize a 194 size bulb for optimal illumination. The replacement chart covers 1975 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 American Motors Pacer uses the 194 bulb for both front and rear side marker positions across all listed model years.
The 194 is an ANSI-standard bulb recognized in both the United States and Canada, operating at 12 volts with a power draw of 3.78 watts.
The 194 bulb follows the T10 miniature wedge form factor, a designation that refers to its tubular shape and wedge-style base, which requires no separate socket retainer to hold it in place.
The wedge base design of the T10 means the bulb is held by tension from the socket contacts alone, making it a tool-free replacement in most applications.
The front side marker on the American Motors Pacer uses the 194 bulb for the 1976-1980 model years.
The rear side marker position covers the 1975-1980 model years with the same 194 bulb specification, giving the rear position one additional model year of coverage compared to the front.
Because both the front and rear side marker positions share the same 194 bulb specification, a single bulb type serves all side marker sockets on the vehicle across the listed years.
At 3.78 watts, the 194 operates at a low wattage consistent with marker and clearance light applications rather than primary illumination functions such as headlamps or brake lights.
