The Dodge Neon brake light utilizes 2458 and 3157 bulb sizes for the lighting system components. Data for the specific bulb requirements covers the range from 1995 through 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Neon uses the 3157 bulb for brake lighting across all model years from 1995-2005.
The 3157 is a dual-filament bulb, meaning it serves two brightness levels within a single unit, typically supporting both running light and brake light functions through separate filaments rated at 7W and 27W respectively.
The 3157 follows the T25 wedge form factor and operates on a 12V electrical system, which is standard for passenger vehicles of this era.
The center high mount stop light (CHMSL) on the Dodge Neon uses the 921 bulb across all model years from 1995-2005.
The 921 is a single-filament wedge bulb in the T15 form factor, rated at 12V and 16W, and is not interchangeable with the 3157 despite both using wedge-style bases.
Both the 3157 and 921 conform to ANSI standards recognized in the United States and Canada, indicating standardized electrical and physical specifications across those markets.
The T25 and T15 designations refer to the tubular bulb body width, with T25 being physically larger than T15, which prevents cross-installation between the two positions.
The dual-filament design of the 3157 means that a failure of one filament does not necessarily disable the other, as the brake and running light circuits operate independently within the same bulb.
