The Dodge Aries brake light utilizes 2057 and 1157 bulb sizes depending on the specific version of the vehicle. Available information covers a production span from 1981 through 1989.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Aries brake light specifications cover model years 1981 through 1989, with the center high mount stop light (CHMSL) specifications covering 1986 through 1989.
The 2057 bulb is the most frequently specified type across these records, appearing in the standard brake light position for the 1982-1989 model years.
The 2057 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a high/low filament draw of 26.9W and 8W respectively, conforming to ANSI standards for the US and Canadian markets.
The 1157 bulb shares the same BAY15d bayonet base as the 2057, which means both types are physically compatible with the same socket, though their wattage ratings differ. The 1157 draws 21W on its high filament compared to the 2057's 26.9W.
Because the 2057 and 1157 share the BAY15d base, the 2057 is generally considered a direct, higher-output substitute for the 1157 in compatible sockets, though the reverse substitution would result in reduced brightness.
The 1981 Dodge Aries uses the 1157 bulb for the standard brake light position, while all subsequent model years in the specifications use the 2057, indicating a change in the specified bulb between the 1981 and 1982 model years.
The 921 is a single-filament wedge-type bulb in the T15 form factor, rated at 12V and 16W, and is the specified bulb for the CHMSL position on the 1986-1989 Dodge Aries.
The wedge base of the 921 is physically distinct from the BAY15d bayonet base used by the 2057 and 1157, making the 921 non-interchangeable with either of those bulb types.
