Jeep Patriot front and rear side marker bulbs use 3757NA and 3157 sizes respectively. The replacement chart covers 2007 to 2017 vehicle production 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 Jeep Patriot uses the 3757NA bulb for the front side marker position across all model years from 2007-2017.
The 3757NA is a dual-filament T25 wedge bulb rated at 12V, distinguished by its natural amber glass construction, which produces an amber output without relying on a colored lens or housing.
The rear side marker position on the Jeep Patriot takes the 3157 bulb across all model years from 2007-2017.
The 3157 is a dual-filament T25 wedge bulb rated at 12V with a wattage split of 27W on the high filament and 7W on the low filament, allowing it to serve both a brighter and a reduced-intensity function within the same housing.
Both the 3757NA and the 3157 share the T25 wedge base format and operate on 12V, placing them in the same broad bulb family despite serving different positions on the vehicle.
Although the 3757NA and 3157 share a physical base type, the natural amber glass coating on the 3757NA is a position-specific requirement for the front side marker, and substituting a clear-glass bulb such as the 3157 in that socket would alter the emitted light color.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating they meet the photometric and dimensional criteria defined by that standardization body for automotive lighting.
The dual-filament design of the 3157 at the rear side marker position means the socket carries wiring for two separate circuits, and single-filament substitutes would not engage both circuits correctly.
