Jeep Patriot front and rear turn signal bulbs utilize 3757NA and 3157 sizes respectively, with the front bulb featuring a distinct larger configuration than the rear unit. The replacement chart documents bulb specifications across vehicle production years spanning 2007 to 2017.
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 turn signal across all model years from 2007-2017.
The 3757NA is a dual-filament T25 wedge bulb rated at 12 volts, distinguished by its natural amber glass envelope, which produces an amber signal output without relying on a colored lens.
The rear turn signal on the Jeep Patriot uses the 3157 bulb across all model years from 2007-2017.
The 3157 is a dual-filament T25 wedge bulb rated at 12 volts with a wattage split of 27W for the high-intensity filament and 7W for the low-intensity filament, making it suitable for combined stop and turn signal functions.
Both the 3757NA and 3157 share the T25 wedge base format and 12-volt operating voltage, placing them in the same physical bulb family.
Despite their physical similarities, the 3757NA and 3157 are not directly interchangeable for the Jeep Patriot. The front position requires the natural amber glass of the 3757NA, while the rear position uses the clear-glass 3157.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and photometric performance requirements.
The dual-filament design of both bulbs allows a single housing to serve more than one lighting function simultaneously, a common arrangement in automotive turn signal and brake light assemblies.
