The Dodge B1500 front turn signal uses 3457, 3157NA, or 2057 bulb sizes, while the rear turn signal requires a 3157 bulb size. The replacement chart covers 1995 to 1998 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge B1500 rear turn signal position uses the 3157 bulb across all four model years covered in the specifications, from 1995-1998.
The 3157 is an ANSI-standard dual-filament wedge bulb in the T25 form factor, rated at 12V with a 27W high filament and 7W low filament.
The front turn signal position varies by model year, with three different bulb types specified across the 1995-1998 range.
The 1995-1996 Dodge B1500 front turn signal uses the 2057, which differs from the other front turn signal bulbs in that it uses a BAY15d bayonet base rather than a wedge base.
The 2057 is rated at 12V with a 26.9W high filament and 8W low filament, and is noted as a brighter variant of the 1157 bulb.
The 1997 front turn signal uses the 3157NA, which is a natural amber glass version of the T25 wedge bulb, rated at 12V, 27W/7W.
The 1998 front turn signal uses the 3457, also a T25 dual-filament wedge bulb rated at 12V, 27W/7W, sharing the same electrical ratings as the 3157 and 3157NA.
Although the 3157, 3157NA, and 3457 share identical voltage and wattage ratings, they are not interchangeable across all positions, as the amber glass of the 3157NA and the specific designations per year indicate position-specific fitment requirements.
The 2057 bayonet base is physically incompatible with the wedge sockets used by the T25-type bulbs, making it non-interchangeable with the 3157, 3157NA, or 3457 without a socket modification.
All four bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
