Additional Notes

The Dodge Journey uses two distinct back up light bulb types across its model years: the 3157 and the 7440, both of which conform to ANSI standards applicable in the United States and Canada.
The 3157 is a dual-filament T25 wedge bulb rated at 12V with a 27W/7W output, meaning it draws 27 watts on its primary filament and 7 watts on its secondary filament.
The 7440 is a single-filament T20 wedge bulb rated at 12V and 21W, making it a simpler, lower-wattage unit compared to the 3157.
For the 2009-2010 Dodge Journey, the 3157 is the sole specified back up light bulb, with no conditional fitment noted for those years.
From 2011-2019, the Dodge Journey requires either a 3157 or a 7440 depending on whether the vehicle is equipped with LED tail lights, making tail light configuration a critical factor in bulb selection.
On 2011-2019 models without LED tail lights, the correct back up light bulb is the 3157, while models with LED tail lights require the 7440 instead.
The 3157 and 7440 are not interchangeable. The T25 and T20 wedge bases differ in size, and the dual-filament versus single-filament construction makes cross-substitution electrically and physically incompatible.
The presence of LED tail lights on the Dodge Journey alters the back up light circuit requirements, which is reflected in the shift from the dual-filament 3157 to the single-filament 7440 in LED-equipped trims.
