Additional Notes

The 211-2 is the most frequently specified dome light bulb for the Dodge Monaco, covering nine of the seventeen model years listed across 1969-1978 (excluding 1971).
The 211-2 is a festoon-type bulb rated at 12V and 12W, with an SV8.5 base and a 41mm length, conforming to ANSI standards for the US and Canadian markets.
The 562 bulb, specified for the Dodge Monaco across 1990-1992, is also a festoon type rated at 12V and 12W, but it uses end-cap contacts rather than the SV8.5 base found on the 211-2.
Although the 562 and 211-2 share identical voltage and wattage ratings, their base types differ, and the two bulbs are not physically interchangeable due to the 3mm difference in length (44mm versus 41mm).
The 1004 bulb was specified for the Monaco across 1965-1968. It is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21/5W output, and is noted as a variant of the 1157.
The dual-filament design of the 1004 is atypical for a dome light application, as dome lights generally require only a single-filament bulb; the second filament in the 1004 goes unused in this fitment.
The 257 bulb was specified solely for the 1971 Monaco. It is rated at just 12V and 2W, making it considerably lower in output than every other bulb type listed in these specifications.
The 257 is described as either a festoon or BA9s base instrument bulb, a dual-base classification that reflects its use across different socket types in various vehicle applications.
The BAY15d bayonet base of the 1004 and the SV8.5 or end-cap festoon bases of the 211-2 and 562 represent three mechanically distinct mounting systems, meaning no cross-substitution is possible among these bulb types without a socket adapter.
All four bulb types listed carry ANSI standardization for the US and Canadian markets, indicating that each conforms to a defined specification rather than being a proprietary or manufacturer-exclusive part.
