The Dodge Aries front and rear turn signal bulb sizes include 2057, 2057NA, and 1156 specifications for this vehicle model. The replacement chart covers 1981 through 1989 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 2057 bulb is the most widely used type across the Dodge Aries turn signal specifications, appearing in both front and rear positions across the majority of model years covered.
The 2057 is a dual-filament bulb operating at 12V with a high-intensity filament rated at 26.9W and a low-intensity filament rated at 8W, mounted on a BAY15d bayonet base.
The 2057 is classified as a brighter variant of the 1157 bulb and conforms to ANSI standards recognized in both the United States and Canada.
The 2057NA variant shares the same electrical ratings, base type, and dual-filament construction as the standard 2057, with the distinction that its glass envelope is natural amber rather than clear.
The Dodge Aries front turn signal used the 2057NA designation for the 1982-1984 model years, indicating factory-specified amber coloring built into the bulb itself rather than the lens.
Front turn signal fitment for the 1981 and 1985-1989 Dodge Aries specifies the clear-glass 2057, which differs from the 2057NA in lens coloring but is otherwise electrically identical.
The rear turn signal for the 1981 Dodge Aries specifies the 1156, a single-filament bulb rated at 12V and 21W with a BA15s bayonet base, which is not interchangeable with the dual-filament 2057 used in all other rear turn signal positions.
The BA15s base of the 1156 and the BAY15d base of the 2057 are physically distinct; the BAY15d has offset locating pins to prevent incorrect installation, while the BA15s has symmetrical pins, making cross-substitution between these two types incompatible.
From 1982 onward, the rear turn signal position on the Dodge Aries transitioned to the 2057, representing a change from the single-filament 1156 used in the 1981 model year.
Because the 2057NA and 2057 share the same base, wattage, and voltage, a substitution between the two affects only the color output of the bulb and depends on whether the housing lens already provides amber coloring.
