The Ram ProMaster front parking light uses a 7440 or 7444NA bulb size, while parking light positions accommodate 7444NA or 7443NA bulb sizes across multiple model generations. The replacement chart covers vehicle production spanning 2014 to 2024 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 7444NA bulb is the most frequently specified front parking light bulb across Ram ProMaster model years, appearing in 2014-2016, 2019-2024 applications, with the exception of one 2023 entry that lists the 7440 instead.
The 7443NA bulb is specified for the Ram ProMaster in 2014, 2015, 2017, and 2018, sharing the same wattage rating and filament configuration as the 7444NA.
Both the 7443NA and 7444NA are dual-filament wedge bulbs in the T20 form factor, rated at 12V with a 21W primary filament and a 5W secondary filament, and both feature natural amber glass.
The natural amber glass in the 7443NA and 7444NA produces a colored output directly from the bulb itself, rather than relying on a tinted lens to achieve the amber appearance required for parking light applications.
The 7440 is a single-filament T20 wedge bulb rated at 12V and 21W, and unlike the 7443NA and 7444NA, it carries no secondary filament and no amber glass coating.
Although the 7440, 7443NA, and 7444NA all share the T20 wedge form factor, the difference in filament count and glass tinting means they are not functionally interchangeable despite their physical similarity.
All three bulb types listed in these specifications conform to ANSI standards applicable in both the United States and Canada.
The Ram ProMaster (2023) has two different front parking light bulb sizes listed across its entries, with one entry specifying the 7440 and another specifying the 7444NA, indicating a possible mid-year or trim-level variation for that model year.
