The Dodge Stratus brake light utilizes 3157 and 3057 bulb sizes for various lighting applications on the vehicle. Data for the specified components covers the period from 1995 through 2006.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Stratus brake light circuit uses two distinct bulb types across its model years: the dual-filament 3057 and 3157 for the main brake lights, and the single-filament 921 for the Center High Mount Stop Light.
The 3057 is an ANSI-standard dual-filament wedge bulb rated at 12V with a 27W high filament and a 7W low filament, housed in a T25 form factor. This type serves the main brake lights on the 1995-2000 Dodge Stratus.
The 3157 shares the same ANSI-standard dual-filament T25 wedge construction and identical 12V, 27W/7W ratings as the 3057, yet it is a distinct part number and is specified for the 2006 model year main brake lights.
Because the 3057 and 3157 share the same wattage ratings and T25 form factor, they are often treated as interchangeable in general automotive practice; however, the Dodge Stratus specifications assign each to separate model years, indicating that substitution should be approached with caution.
The dual-filament design of both the 3057 and 3157 allows a single bulb to serve two lighting functions, with the higher 27W filament activating for braking and the lower 7W filament typically used for a secondary function such as a tail light.
The 921 is an ANSI-standard single-filament wedge bulb rated at 12V and 16W, housed in a T15 form factor. It is specified for the Center High Mount Stop Light across all listed model years of the Dodge Stratus, from 1995 through 2006.
The T15 form factor of the 921 is physically smaller than the T25 form factor used by the 3057 and 3157, making the two bulb families non-interchangeable by size alone.
The Center High Mount Stop Light on the Dodge Stratus uses a single-filament bulb rather than a dual-filament type, consistent with its dedicated function as a supplemental brake signal with no secondary lighting role.
