The Dodge Spirit brake light utilizes 3157, 2458, and 3057 bulb sizes depending on the specific version of the vehicle. Data for the components covers the period from 1989 through 1995.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Spirit uses three bulb types across its brake lighting system: the 3157, the 3057, and the 921, all of which conform to ANSI standards recognized in the United States and Canada.
The 3157 and 3057 are both dual-filament wedge bulbs rated at 12V with a 27W/7W output, meaning the higher wattage filament activates for braking while the lower wattage filament serves a secondary function such as running light operation.
Both the 3157 and 3057 share the T25 wedge form factor, which refers to the physical shape and base style of the bulb.
Despite their shared form factor and identical wattage ratings, the 3157 and 3057 are distinct part numbers and are not universally interchangeable, as differences in filament positioning between the two types can affect fitment and function in sockets designed for one or the other.
The Dodge Spirit (1992-1995) uses the 3157 for the brake light, while the 1989-1991 model years use the 3057 for the same position.
The 921 is a single-filament wedge bulb rated at 12V and 16W, housed in a T15 form factor, which is physically smaller than the T25 used by the 3157 and 3057.
The 921 bulb serves the Center High Mount Stop Light across all Dodge Spirit model years from 1989-1995, making it the only bulb type in these specifications that remains consistent across the entire production span covered.
