The Dodge Journey tail light utilizes 3157 and 2458 bulb sizes for illumination across various production versions. Information provided covers the specific time period from 2009 through 2019 for the listed components.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Journey inner tail light position uses two distinct socket types across its production years: the T25 wedge base and the T20 wedge base. These two base sizes are not interchangeable, as the T25 is physically larger than the T20.
The 3157 is the most frequently specified bulb across the inner tail light position, covering the 2009-2019 model years in that application. It is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and a 7W low filament.
The dual-filament design of the 3157 allows a single bulb to serve two lighting functions simultaneously, typically combining tail light and brake light or turn signal duties within one housing.
The 3757NA shares the same T25 wedge base as the 3157 and appears in the inner tail light position for the 2010 and 2012 model years. Its natural amber glass envelope produces a yellow-orange output without requiring an external amber lens.
The 7440 is a single-filament T20 wedge bulb rated at 12V and 21W. It is specified for the Dodge Journey inner tail light in the 2011 model year only, and its single-filament construction means it serves only one lighting function per socket.
Because the 3757NA and 3157 share the T25 base, physical fitment between them is possible, but the amber glass coating of the 3757NA affects light color output. Substituting one for the other may alter the color of the emitted light depending on the lens color of the housing.
For the 2013-2019 model years, the 3157 specification carries a "Without LED Tail Lights" condition, indicating that the halogen bulb fitment applies only to vehicles not equipped with the LED tail light package.
All three bulb types listed, the 3157, 3757NA, and 7440, conform to ANSI standards applicable in both the United States and Canada, meaning they meet the same electrical and photometric requirements in both markets.
