Additional Notes

The Dodge Grand Caravan dome light uses four distinct bulb sizes across its model history: 578, 579, 212-2, and 211-2, all of which are ANSI-standardized festoon-type bulbs rated at 12V and 12W.
All four bulb types share the same voltage and wattage rating, meaning the electrical load placed on the dome light circuit remained consistent across the entire model range covered by these specifications.
The 578 bulb is the most widely specified size, covering the Dodge Grand Caravan from 2001-2019, and features a 41mm length with end-cap contacts.
The 579 bulb, specified for the 1996-2000 model years, is physically longer at 44mm compared to the 578, despite sharing the same end-cap contact design and identical voltage and wattage ratings.
Because the 578 and 579 differ in length by 3mm, the two bulbs are not directly interchangeable, even though their electrical characteristics are identical.
The 212-2 bulb, used on the 1992-1995 model years, shares the same 41mm length as the 578 but uses an SV8.5 base rather than end-cap contacts, making it physically incompatible with the 578 socket.
The SV8.5 base is a bayonet-style festoon base with side-mounted contact pins, which is a different mounting and contact mechanism from the spring-tension end-cap design used by the 578 and 579.
The 211-2 bulb, specified for the 1987-1991 model years, shares the same 41mm length and SV8.5 base as the 212-2. The two bulbs differ by part number designation, which typically reflects minor internal construction differences between manufacturers rather than dimensional ones.
Because the 212-2 and 211-2 share the same base type and length, they are generally considered cross-compatible in many fitment references, though the specifications list them as distinct part numbers for their respective year ranges.
The transition from the SV8.5-based bulbs to the end-cap festoon design occurred between the 1995 and 1996 model years, representing a socket-level change that makes bulbs from those two groups incompatible with each other.
