Additional Notes

The 1004 bulb is the specified dome light size for the Dodge 330 across its 1963-1964 model years.
The 1004 is an ANSI-standardized bulb type recognized in both the United States and Canada.
It operates on a 12-volt electrical system, consistent with the standard automotive voltage of that era.
The 1004 carries a dual-filament design rated at 21/5 watts, meaning each filament serves a distinct output level.
Its base type is the BAY15d bayonet mount, a two-pin offset bayonet configuration that physically prevents incorrect insertion of single-filament alternatives.
The 1004 is a variant of the 1157 bulb family, though the two are not directly interchangeable in all applications due to differences in wattage and base pin offset specifications.
