Additional Notes

The Dodge Dakota map light bulb specification covers model years 1987-2010, with six distinct bulb types used across that span: 192, 194, 578, 579, 212-2, and 912.
The 192 bulb is the most frequently specified type, covering the Dodge Dakota from 2002-2010. It is a T10 miniature wedge bulb rated at 12V and 3W, conforming to ANSI standards for the US and Canada.
The 194 bulb, used in the 2001 model year, shares the same T10 miniature wedge form factor as the 192 but draws slightly more power at 3.78W. Despite the physical similarity, the two bulbs are not identical in wattage and are not confirmed interchangeable by these specifications.
The 578 and 579 are both festoon-style bulbs rated at 12V and 12W, used in the 2000 and 1999 model years, and the 1998 and 1997 model years, respectively. Festoon bulbs make contact at both ends of the bulb body rather than through a base socket.
The 578 has a 41mm length, while the 579 measures 44mm. The difference in length means the two types are not interchangeable, as festoon bulb fitment depends on the physical distance between the contact points in the housing.
The 212-2 bulb, specified for 1994-1996, is also a festoon-style bulb at 41mm and 12V/12W. However, it uses an SV8.5 base rather than plain end-cap contacts, distinguishing it from the 578 despite sharing the same length and power rating.
Because the 578 and 212-2 share a 41mm length but differ in base type, they are not interchangeable. Substituting one for the other would result in a fitment mismatch at the socket.
The 912 bulb, specified for the Dodge Dakota from 1987-1991, is a T15 wedge bulb rated at 12V and 12W. It is noted as a variant of the 921 bulb, meaning the two share close physical and electrical characteristics, though the specifications reference only the 912 for this application.
The T10 wedge bulbs used in 2001-2010 operate at significantly lower wattage (3-3.78W) compared to the festoon and T15 wedge types used in earlier years, which all operate at 12W.
All bulb types listed across the full model year range conform to ANSI standards applicable in both the US and Canada.
