The Dodge Mini Ram front and rear turn signal bulbs utilize either 2057 or 1157 size specifications. The replacement chart covers 1984 through 1988 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 Dodge Mini Ram uses two bulb types across its turn signal positions: the 2057 and the 1157, both of which are ANSI-standardized for the US and Canadian markets.
Both the 2057 and 1157 are dual-filament bulbs, meaning each serves two lighting functions within a single housing, typically combining turn signal and parking light duties.
Both bulb types share the BAY15d bayonet base, a two-pin offset base design that physically fits the same socket.
The 2057 operates at 12V with a wattage of 26.9W on its high-filament and 8W on its low-filament, while the 1157 operates at 12V with 21W and 5W respectively.
The higher wattage of the 2057 high-filament, 26.9W versus the 1157's 21W, makes the 2057 the brighter of the two bulb types.
For the Dodge Mini Ram (1985-1988), both the front and rear turn signal positions specify the 2057 bulb.
The 1984 Dodge Mini Ram specifies the 1157 bulb for both the front and rear turn signal positions, distinguishing it from all later model years in these specifications.
Although the BAY15d base is shared between the 2057 and 1157, substituting one for the other results in a difference in output brightness due to the wattage gap between the two types.
