Additional Notes

The Chrysler Voyager uses the 578 bulb for the map light across the 2000-2003 model years.
The 578 is an ANSI-standardized bulb, meaning its specifications are governed by a recognized North American industry standard applicable in both the US and Canada.
The 578 bulb follows a festoon design, which is a cylindrical form factor held in place by spring-loaded end caps rather than a socket base.
The 41mm length is a critical fitment factor, as festoon bulbs must physically span the distance between their mounting contacts to seat correctly.
End-cap contacts on the 578 mean electrical connection is made at both ends of the bulb rather than through a base pin or wedge, which is characteristic of the festoon type.
The 578 operates at 12 volts, consistent with standard automotive electrical systems.
At 12 watts, the 578 draws a relatively modest amount of power for an interior lighting application.
Because the 578 is an ANSI-standardized part, it is produced by multiple manufacturers, and any 578-rated bulb meeting the 41mm festoon specification is considered a direct replacement for the Chrysler Voyager map light.
