American Motors Rebel Dome Light Bulb Size

The American Motors Rebel dome light utilizes 562, 1004, and 1003 bulb sizes depending on the specific production period. Data for the lighting components covers the period from 1958 through 1970.

Additional Notes

The American Motors Rebel dome light specifications cover model years 1958-1970, with three distinct bulb types used across that span.
The 1003 bulb is an ANSI-standard single-filament unit with a BA15s bayonet base, rated at 12V and 21W, and it serves the American Motors Rebel for the 1958-1959 model years.
The BA15s bayonet base on the 1003 bulb features a single contact pin, which is a defining physical trait that distinguishes it from bayonet bases carrying multiple pins.
The 1004 bulb is an ANSI-standard dual-filament unit with a BAY15d bayonet base, rated at 12V with a 21/5W output, and it covers the Rebel from 1960-1961 and again from 1966-1968.
The BAY15d base on the 1004 bulb carries two offset contact pins, a configuration that physically prevents installation of single-filament bayonet bulbs in the same socket.
The 1004 is noted as a variant of the 1157, meaning the two share the same BAY15d base and general construction, though they are not identical and the specifications list only the 1004 for this application.
The 562 festoon bulb is an ANSI-standard unit rated at 12V and 12W, with a 44mm length and end-cap contacts, and it is specified for the Rebel in 1969-1970.
Festoon bulbs make contact through metal caps at each end rather than through a base, meaning the socket type for the 562 is fundamentally different from the bayonet sockets used by the 1003 and 1004.
The shift from the 1004 bayonet bulb in 1968 to the 562 festoon bulb in 1969 reflects a change in socket design between those model years, and the two bulb types are not interchangeable.
All three bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
