Additional Notes

The Chrysler Voyager back up light specifications cover two distinct bulb types across the listed model years: the 7440 and the 3057.
The 7440 is the specified back up light bulb for the Chrysler Voyager across the 2020-2024 model years.
The 3057 is the specified back up light bulb for the 2000-2003 model years.
The 7440 is a single-filament wedge bulb in the T20 form factor, rated at 12V and 21W, and follows the ANSI standard used in the US and Canada.
The 3057 is a dual-filament wedge bulb in the T25 form factor, rated at 12V with filaments drawing 27W and 7W respectively, also conforming to the same ANSI standard.
The T25 form factor of the 3057 is physically larger than the T20 form factor of the 7440, which means the two bulbs are not interchangeable despite both being wedge-type designs.
The dual-filament construction of the 3057 serves two separate electrical circuits at different wattages, whereas the single-filament 7440 serves only one circuit, further distinguishing their functional roles and fitment requirements.
Both bulb types operate on a standard 12V automotive electrical system, consistent with conventional passenger vehicle architecture.
