The Dodge 600 brake light utilizes a 2057 bulb size for illumination across all available vehicle configurations listed in the provided technical data. Information covers the period from 1983 through 1988 without any changes to the specified component requirements.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge 600 uses the 2057 bulb for brake lighting across all six model years covered, spanning 1983-1988.
The 2057 is a dual-filament bulb with a BAY15d bayonet base, operating at 12V with a high filament draw of 26.9W and a low filament draw of 8W.
As a dual-filament design, the 2057 serves both a steady running light function and a brighter stop light function within a single unit.
The 2057 is classified as a brighter variant of the 1157 bulb. While the two share the same BAY15d base type, they are not identical in output, and substituting one for the other may produce different light intensity results.
The center high mount stop light (CHMSL) on the Dodge 600 uses the 921 bulb for model years 1986-1988.
The 921 is a single-filament wedge-type bulb in a T15 form factor, rated at 12V and 16W, which differs structurally from the BAY15d bayonet base used by the 2057.
Because the 921 uses a wedge base and the 2057 uses a bayonet base, the two bulb types are not physically interchangeable with each other.
Both the 2057 and 921 conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical specifications within those markets.
