Plymouth Arrow Pickup front and rear turn signal bulbs use 1157 size bulbs for replacement applications. The replacement chart covers 1979 to 1982 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 Pickup uses the 1157 bulb for both front and rear turn signals across the 1979-1982 model years.
The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, allowing it to serve two distinct lighting functions at different wattages.
It operates on a 12-volt electrical system and draws 21 watts on the high-filament circuit and 5 watts on the low-filament circuit.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights on the base to ensure correct orientation during installation and prevent incorrect filament activation.
The 1157 carries ANSI standardization, meaning its physical and electrical specifications conform to a recognized North American standard applicable in both the United States and Canada.
Because the same bulb number applies to both the front and rear turn signal positions across all four model years, a single bulb type services all turn signal sockets on the vehicle.
The dual-filament design of the 1157 is commonly employed in automotive applications where one socket must handle both a steady running light function and a higher-intensity flashing or braking function.
The BAY15d base is not interchangeable with single-filament bayonet bases such as the BA15s, as the pin configuration differs to prevent single-filament bulbs from being seated in dual-filament sockets.
