Additional Notes

The Dodge 600 map light draws from three distinct ANSI-standard bulb types across its model years: the 194, 37, and 912.
The 912 bulb is the most frequently specified across these years, fitting the 1983-1985 Dodge 600 map light position.
The 912 is a T15 wedge bulb rated at 12V and 12W, and it is a recognized variant of the 921 bulb.
Because the 912 is a variant of the 921 rather than a direct equivalent, substitution with a 921 warrants verification before use, as wattage and fitment tolerances may differ.
The 1988 Dodge 600 uses the 194, a T10 miniature wedge bulb rated at 12V and 3.78W, which is among the most widely used automotive interior bulb types under ANSI standards.
The 1987 Dodge 600 uses the 37, a T5 miniature wedge bulb rated at 12V and 1W, making it the lowest-wattage map light bulb specified across these model years.
All three bulb types follow ANSI standards applicable in both the United States and Canada.
The T5, T10, and T15 designations refer to the bulb's tubular body size in increments of one-eighth of an inch, meaning these three bulbs differ physically and are not interchangeable across the model years listed.
The wattage variation across these bulbs ranges from 1W to 12W, reflecting meaningful differences in electrical draw that affect compatibility with the original socket and wiring.
All specified bulbs operate on a 12V system, consistent with standard automotive electrical architecture.
