The Ram ProMaster City parking light requires bulb size 9005 or 7440 depending on the specific version of the vehicle. Data for the lighting components covers the range from 2015 to 2018.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 7440 is a single-filament wedge bulb in the T20 form factor, rated at 12V and 21W. It appears in the Ram ProMaster City front parking light position for the 2015-2016 and 2022 model years.
The 7444NA shares the same T20 wedge form factor and 12V/21W single-filament rating as the 7440 but adds a second filament rated at 5W and uses natural amber glass rather than a clear envelope. This dual-filament construction and amber tinting distinguish it from the standard 7440 despite the physical similarity.
Although the 7440 and 7444NA occupy the same T20 wedge housing, they are not directly interchangeable. The 7444NA carries a second filament and factory amber coloring, meaning substituting a clear 7440 would alter both the electrical behavior and the light output color of the 2021 front parking light.
The 9005 is a single-filament halogen bulb with a P20d base, rated at 12V and 65W. At 65W, it draws significantly more power than the T20 wedge types used in other model years of the same position.
The P20d base of the 9005 is a locking bayonet-style connector, physically incompatible with the wedge socket used by the 7440 and 7444NA. This makes the 9005 non-interchangeable with either T20 bulb regardless of voltage matching.
The 2017-2018 Ram ProMaster City front parking light uses the 9005, a bulb type more commonly associated with high-beam headlight applications in other vehicles, rather than the lower-wattage T20 wedge types found in the surrounding model years of this same position.
All three bulb types listed are rated to the ANSI standard applicable in the United States and Canada, indicating compliance with North American automotive lighting specifications.
