Additional Notes

The American Motors Rebel uses the 1156 bulb for the back up light across the 1960-1961 and 1966-1970 model years.
The 1156 is an ANSI-standard single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base.
The 1958-1959 Rebel uses the 1073 bulb for the back up light instead of the 1156.
The 1073 is also an ANSI-standard single-filament bulb with a BA15s bayonet base, but it is rated at a lower 13W while sharing the same 12V operating voltage.
Because both the 1156 and 1073 share the BA15s bayonet base, they are physically compatible with the same socket, though their wattage ratings differ.
Substituting a 1156 for a 1073 in a 1958-1959 Rebel would introduce a higher wattage draw than the original specification, which may affect the electrical circuit designed around the lower-rated bulb.
