The Dodge Journey front turn signal requires a 3757NA bulb size, while rear turn signal applications utilize 3157, 7440NA, or 3757NA bulb sizes depending on configuration. The replacement chart covers 2009 through 2019 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Journey uses the 3757NA bulb for the front turn signal across all model years in the specifications, spanning 2009-2019. This bulb is a dual-filament T25 wedge type rated at 12V, with natural amber glass that produces an amber color output without the need for a colored lens or housing filter.
The "NA" suffix in bulb designations such as 3757NA and 7440NA stands for natural amber, referring to the tinted glass envelope of the bulb itself. This is distinct from clear-glass equivalents in the same bulb family, which rely on an amber-colored lens to produce the required turn signal color.
The 3757NA and 3157 are both dual-filament T25 wedge bulbs operating at 12V, yet they are not the same part. The 3157 carries a published wattage rating of 27W/7W for its high and low filaments respectively, while the 3757NA has a natural amber glass envelope. These differences make them non-interchangeable despite sharing the same T25 form factor.
For the rear turn signal on the Dodge Journey, the correct bulb depends on whether the vehicle is equipped with LED tail lights. Models without LED tail lights use the 3157, while models with LED tail lights use the 7440NA. This distinction applies across the 2011-2019 model years.
The 7440NA is a single-filament T20 wedge bulb rated at 12V and 21W with a natural amber glass envelope. Its single-filament design and smaller T20 form factor mean it is not physically or electrically interchangeable with the dual-filament T25 bulbs used in other positions on the same vehicle.
The 2009 Dodge Journey uses the 3757NA for both the front and rear turn signals, making it the only model year in the specifications where the same bulb type is shared across both positions.
The 2010 Dodge Journey rear turn signal uses the 3157 without any LED tail light variant listed, distinguishing it from the 2011-2019 model years, which carry two rear turn signal options based on tail light configuration.
All three bulb types in the specifications, the 3757NA, 3157, and 7440NA, conform to ANSI standards applicable in both the United States and Canada, indicating a standardized electrical and physical specification shared across North American markets.
