The Jeep Compass parking light utilizes 3757NA, 7443NA, and 7444NA bulb sizes depending on the specific version of the vehicle. Data for the lighting components covers the range from 2007 to 2018.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The front parking light positions across the Jeep Compass model years covered in these specifications use three bulb sizes: 7444NA, 7443NA, and 3757NA, all of which are dual-filament wedge bulbs with natural amber glass.
Natural amber glass, denoted by the "NA" suffix in each bulb designation, produces an amber-colored output directly from the glass envelope rather than relying on a clear bulb paired with an amber lens.
The 7444NA and 7443NA are both T20 wedge bulbs rated at 12V with a 21W/5W dual-filament configuration, where the higher wattage filament serves the brighter function and the lower wattage filament serves the dimmer running or parking function.
The 3757NA is a T25 wedge bulb, which has a physically larger base than the T20 form factor used by the 7444NA and 7443NA, making these two groups not interchangeable despite sharing a dual-filament wedge design.
All three bulb sizes carry ANSI standardization applicable to the United States and Canada, meaning they conform to a defined set of electrical and physical specifications recognized across those markets.
The Jeep Compass (2007-2010) front parking light position takes the 3757NA bulb, while later model years in the specifications transition to T20-based bulbs.
Although the 7444NA and 7443NA share the same voltage, wattage, filament count, glass type, and T20 form factor, they carry distinct ANSI designations, and substituting one for the other without confirming socket compatibility is not advised.
The 2021-2022 Compass front parking light uses the 7444NA, while the 2018 model year uses the 7443NA, reflecting that the same generation of a vehicle can reference different bulb designations across its production span.
