Additional Notes

The Dodge Dakota uses three distinct dome light bulb sizes across its model years, all of which are festoon-type bulbs operating at 12 volts and 12 watts.
Festoon bulbs are cylindrical lamps that mount horizontally between two spring-loaded contacts or a fixed base, a format common in interior automotive lighting applications.
The 578 bulb is specified for the Dodge Dakota across the 2001-2010 model years. It is an ANSI-standard festoon bulb with a 41mm length and end-cap contacts.
The 579 bulb is specified for the 1997-2000 model years. It shares the same 12V, 12W rating as the 578 but has a 44mm length, making the two bulbs physically non-interchangeable despite their similar appearance.
The 211-2 bulb is specified for the 1995-1996 model years. Although it is also 41mm in length and rated at 12V and 12W, it uses an SV8.5 base rather than end-cap contacts, which distinguishes it from the 578.
The SV8.5 base on the 211-2 bulb refers to a single-contact bayonet-style festoon base with an 8.5mm socket width, a mounting format that is not compatible with fixtures designed for end-cap festoon bulbs.
Because the 578 and 211-2 share the same 41mm length but differ in base type, substituting one for the other in the Dodge Dakota would result in a fitment failure regardless of the physical length match.
All three bulb types conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical tolerances across manufacturers.
