Additional Notes

The Chrysler 200 uses the 578 bulb for the dome light across all specified model years, spanning 2011-2017.
The 578 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket.
At 41mm in length, the 578 fits within a spring-loaded festoon housing, where the end caps press against two opposing contact points to complete the circuit.
The 578 operates at 12 volts and 12 watts, which is consistent with standard automotive interior lighting powered directly from a vehicle's 12V electrical system.
The 578 carries ANSI designation, indicating it conforms to a standardized specification recognized in both the United States and Canada.
Because the 578 is an ANSI-standardized festoon bulb, aftermarket and OEM replacements from different manufacturers are generally interchangeable provided the 41mm length and end-cap contact design are matched exactly.
