American Motors Concord front and rear side marker bulbs use a 194 size bulb for all applications. The replacement chart covers 1978 to 1983 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 American Motors Concord uses the 194 bulb in both the front and rear side marker positions across the 1978-1983 model years.
The 194 is classified as a miniature wedge bulb, designated T10 in the tubular bulb sizing system, where the number 10 represents the width in eighths of an inch.
The wedge base design means the bulb is held in its socket by the tension of the base itself rather than by a separate metal contact pin, which is a common trait of low-wattage automotive signal and marker bulbs.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-power range typical of marker and courtesy lighting applications.
The 194 conforms to ANSI standards recognized in both the United States and Canada, meaning the specification reflects a standardized electrical and physical profile rather than a proprietary one.
Because the front and rear side marker positions on the Concord share the same 194 bulb, a single bulb type serves both locations across the entire production run covered by these specifications.
The T10 form factor is widely used across many vehicle makes and model years, which means the 194 bulb is not exclusive to this application and is broadly available in the general automotive replacement market.
Substitution with bulbs of a different wattage or base type is not supported by these specifications, as the 194 is the designated size for all listed positions and years.
