The Dodge Mini Ram brake light requires 1157 and 2057 bulb sizes for the rear lighting system. Data for the specified components covers the period from 1984 through 1988.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Mini Ram brake light specifications cover model years 1984-1988, with the center high mount stop light (CHMSL) specifications applying to 1985-1986.
Two bulb types appear across the brake light positions of the Dodge Mini Ram: the dual-filament 1157 and 2057 for standard brake lights, and the single-filament 921 for the CHMSL.
The 1157 bulb is an ANSI-standard dual-filament bulb rated at 12V with a 21W high filament and 5W low filament, mounted via a BAY15d bayonet base. It is used in the 1984, 1987, and 1988 model years.
The 2057 bulb shares the same BAY15d bayonet base as the 1157 and is also an ANSI-standard dual-filament bulb rated at 12V, but draws 26.9W on the high filament and 8W on the low filament. It is fitted to the 1985-1986 model years.
Although the 1157 and 2057 share the same BAY15d bayonet base and are physically interchangeable in terms of fitment, their wattage ratings differ. The 2057 draws noticeably more power on both filaments, which is a relevant consideration when substituting one for the other.
The 921 is a single-filament wedge-type bulb (T15 form factor) rated at 12V and 16W. Its wedge base design is physically distinct from the BAY15d bayonet base used by the 1157 and 2057, making cross-substitution between these types impossible without a socket adapter.
The CHMSL on the 1985-1986 Dodge Mini Ram uses the 921 bulb, which operates as a single-filament stop light only, consistent with the dedicated stop-light function of a center high mount position.
All three bulb types listed conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical specifications across those markets.
