Plymouth Champ front and rear side marker bulbs utilize a 194 size across both positions. The replacement chart covers 1979 to 1982 production years with corresponding bulb 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 Plymouth Champ across all side marker positions for the 1979-1982 model years.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, classifying it as a regionally standardized automotive lamp.
It is a miniature wedge-type bulb, designated T10, which refers to its tubular shape with a width of 10 thirty-seconds 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 or bayonet fitting.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles of that era.
Its power rating of 3.78 watts places it in the low-wattage category, typical of marker and clearance lamp applications where illumination intensity requirements are modest.
The Plymouth Champ uses the same 194 bulb in both the front and rear side marker positions, meaning a single bulb type serves all four side marker sockets on the vehicle.
Because the front and rear side marker bulbs share an identical specification, a bulb removed from one position is physically interchangeable with any of the remaining three positions on the same vehicle.
