Additional Notes

The Chevrolet Kingswood dome light specifications cover model years 1959-1961 and 1969-1972, with two distinct bulb types used across those years.
The 211-2 is the more widely used of the two bulb types, appearing in the Kingswood across 1961 and 1969-1972.
The 211-2 is a festoon-style bulb, meaning it is cylindrical in form and held in place by contact pressure at each end rather than by a base socket.
The 211-2 operates at 12 volts with a 12-watt output, uses an SV8.5 base, and has a 41mm length. It conforms to ANSI standards applicable in the US and Canada.
The 1004 was used in the Chevrolet Kingswood for the 1959-1960 model years and is a dual-filament bulb with a BAY15d bayonet base.
The BAY15d bayonet base on the 1004 features two filaments at offset pin positions, a design that prevents incorrect installation by ensuring the bulb can only be seated in one orientation.
The 1004 operates at 12 volts with a 21/5-watt dual-filament output and is noted as a variant of the 1157. Like the 211-2, it conforms to ANSI standards for the US and Canada.
The 211-2 and 1004 are not interchangeable. They differ in base type, physical form, wattage, and filament count, making cross-substitution between the two bulb types incompatible with the dome light socket of each respective model year.
