Plymouth Arrow front and rear side marker bulbs utilize 67 and 194 bulb sizes across the model line. The replacement chart covers 1976 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 Plymouth Arrow uses two distinct bulb types across its 1976-1980 side marker positions: the 67 and the 194, both of which are ANSI-standardized for the US and Canadian markets.
The 1978-1980 model years use bulb 67 for both the front and rear side marker positions, while the 1976-1977 model years use bulb 194 in both positions.
The front and rear side marker positions share the same bulb type within any given model year, meaning no cross-position substitution is required when servicing the Plymouth Arrow.
Bulb 67 is a single-filament type with a BA15s bayonet base, operating at 12V and 8W. The BA15s base features a single contact pin, which distinguishes it from dual-contact bayonet variants.
Bulb 67 is described as a lower wattage variant of the 1156, which means the two share the same BA15s bayonet base style but differ in wattage output. The 1156 is not a direct replacement for the 67 in this application.
Bulb 194 is a miniature wedge type in the T10 form factor, operating at 12V and 3.78W. Its wedge base design requires no separate socket retainer, as the bulb body itself creates the electrical contact.
The 194 operates at significantly lower wattage than the 67, and the two bulbs use entirely different base types, making them physically incompatible with each other's sockets.
