Dodge Nitro front and rear side marker bulbs utilize a 168 bulb size for the front position and 3057 or 4057 bulb sizes for the rear position. The replacement chart covers vehicle production years spanning 2007 to 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Nitro uses the 168 bulb for the front side marker position across all model years covered in the specifications, spanning 2007-2011.
The 168 is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W, making it a low-wattage single-filament lamp suited for marker lighting.
The rear side marker position of the Dodge Nitro uses a dual-filament wedge bulb, though the specific size varies depending on the model year.
Model years 2007-2009 use the 4057 bulb at the rear side marker position, while 2010-2011 use the 3057 bulb instead.
Both the 3057 and 4057 are ANSI-standard T25 wedge bulbs rated at 12V with a dual-filament output of 27W on the high filament and 7W on the low filament.
Despite sharing the same T25 form factor, voltage rating, and wattage values, the 3057 and 4057 are distinct part numbers and are not confirmed as interchangeable within these specifications.
The front and rear side marker positions on the Nitro use bulbs from different form factor families, the T10 at the front and the T25 at the rear, meaning the two positions do not share a common bulb size.
