Chrysler Voyager Dome Light Bulb Size

The Chrysler Voyager dome light requires bulb size 578 or 579 depending on the specific configuration of the interior lighting system. Data for the bulb requirements covers the range from 2000 to 2021.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The 578 and 579 are both ANSI-standardized festoon bulbs used in North American markets. Festoon bulbs are cylindrical in form and make electrical contact through metal caps at each end rather than through a base pin or wedge.
The 578 bulb is rated at 12V and 12W, with a 41mm length. The 579 bulb shares the same 12V and 12W electrical rating but has a 44mm length, making the two physically distinct despite their identical power characteristics.
The Chrysler Voyager uses the 578 bulb for the dome light across the 2001-2003 and 2021 model years.
The 2000 Chrysler Voyager uses the 579 bulb for the dome light, which differs in length from the 578 used in surrounding model years.
Because the 578 and 579 share the same voltage and wattage, the electrical load on the vehicle's circuit is consistent across all listed model years.
The 3mm difference in length between the 578 and 579 is a fitment-critical factor. A festoon bulb that is too short or too long for its housing may not make reliable contact with the end-cap terminals, or may not seat securely within the fixture.
The 578 and 579 are not interchangeable in the Chrysler Voyager despite their electrical equivalence, as the dome light housing is sized to accept a specific bulb length for each model year.
