Additional Notes

The two bulb types specified for the Dodge Stratus dome light are the 578 and 579, both of which are festoon-style bulbs operating at 12 volts and 12 watts.
Festoon bulbs are cylindrical lamps that make electrical contact through metal caps at each end rather than through a base socket, which is why they are also referred to as end-cap contact bulbs.
The 578 and 579 share identical voltage and wattage ratings, but they differ in physical length. The 578 measures 41mm and the 579 measures 44mm.
The Dodge Stratus (1995-2000) takes the 578 bulb for the dome light position.
The 2006 Stratus uses the 579 bulb instead, making the two sizes non-interchangeable across model years despite their otherwise similar electrical characteristics.
Both the 578 and 579 are classified under ANSI standards recognized in the United States and Canada, meaning the size designations are standardized rather than proprietary to any single manufacturer.
The 3mm length difference between the 578 and 579 is significant in festoon applications because the bulb must physically span the socket housing. Installing a bulb of the wrong length can result in poor contact or no contact at all.
