The Dodge Intrepid front turn signal requires a 3157NA bulb size, while rear turn signals use either 3157 or 3057 bulb sizes. The replacement chart covers 1993 through 2004 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Intrepid front turn signal uses the 3157NA bulb across all model years from 1993-2004, making it the most consistent fitment in these specifications.
The 3157NA is a dual-filament T25 wedge bulb rated at 12V with a 27W high-filament and 7W low-filament output, distinguished by its natural amber glass envelope, which produces an amber signal color without relying on a colored lens.
The 3157 and 3157NA share identical electrical ratings of 12V, 27W/7W and the same T25 wedge base, with the only difference being that the 3157NA carries a natural amber glass coating while the 3157 has clear glass.
The rear turn signal on the Dodge Intrepid uses the 3157 for 1993-1994 and again for 1998-2004, while 1995-1997 models use the 3057 instead.
The 3057 is also a dual-filament T25 wedge bulb rated at 12V, 27W/7W and follows the same ANSI standard as the 3157, though the two are not fully interchangeable due to differences in filament positioning within the base.
All three bulb types in these specifications, the 3157NA, 3157, and 3057, conform to ANSI standards applicable in both the United States and Canada.
Because the 3157 and 3057 share the same T25 wedge base and wattage ratings, they are sometimes confused, but substituting one for the other in the rear turn signal position may affect socket fit or circuit function depending on the housing design.
The dual-filament design of all bulbs listed here allows a single bulb to serve both a running light function on the low-filament and a turn or brake signal function on the high-filament.
