Additional Notes

The 7440 is the daytime running light bulb size for the Ram ProMaster City across all listed model years, spanning 2015-2022.
The 7440 bulb follows the ANSI standard recognized in both the United States and Canada, placing it within a regulated specification framework used across the North American automotive market.
This bulb belongs to the T20 wedge family, a designation that refers to its physical form factor. The wedge base design means the bulb is held in place by friction rather than a bayonet or screw mechanism.
The 7440 operates at 12 volts and 21 watts, which are standard values for a single-filament automotive wedge bulb intended for daytime running light applications.
The single-filament construction of the 7440 distinguishes it from the 7443, a closely related T20 wedge bulb that carries a dual-filament design. These two types are not interchangeable despite sharing the same physical base style, as the socket wiring differs between single- and dual-filament configurations.
