The Dodge Nitro brake light utilizes 3057 and 4057 bulb sizes for the specific lighting components. Data for the provided specifications covers the range from 2007 through 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Nitro brake light system uses three bulb types across its model years: the 3057, 4057, and 921, all of which conform to ANSI standards recognized in both the United States and Canada.
The 3057 and 4057 are both dual-filament wedge bulbs in the T25 form factor, rated at 12V with a 27W/7W power split between the stop and tail filaments respectively.
Despite sharing identical electrical ratings and the same T25 form factor, the 3057 and 4057 are distinct part numbers and are not listed as interchangeable within the Dodge Nitro specifications.
The Dodge Nitro uses the 4057 for the brake lights across the 2007-2009 model years, while the 3057 replaces it for the 2010-2011 model years.
The 921 is a single-filament wedge bulb in the T15 form factor, rated at 12V and 16W, and serves a different function than the dual-filament T25 bulbs used in the standard brake lights.
The 921 bulb is specified for the Center High Mount Stop Light on the Dodge Nitro for the 2007-2009 model years.
The T15 form factor of the 921 is physically smaller than the T25 used by the 3057 and 4057, making the bulb types non-interchangeable by size alone.
The single-filament design of the 921 reflects its dedicated stop-light function in the Center High Mount Stop Light, which does not require a secondary tail-light filament.
