Additional Notes

The American Motors Hornet uses the 561 bulb for the dome light across the 1971-1977 model years, while the 1970 model year uses the 562 bulb instead.
Both the 561 and 562 are ANSI-standardized festoon bulbs recognized in the US and Canada, each operating at 12 volts and 12 watts.
Festoon bulbs make contact at both ends of the bulb body rather than through a base socket, which is a defining characteristic of the festoon form factor.
Both bulbs share a 44mm length and use end-cap contacts, meaning their physical construction is identical in those respects.
Despite the shared physical format and electrical ratings between the 561 and 562, they carry distinct ANSI designations, which can indicate differences in filament type, light output, or other internal characteristics not reflected in voltage and wattage alone.
The single-year use of the 562 in the 1970 American Motors Hornet, followed by a shift to the 561 from 1971 onward, represents a fitment distinction that warrants attention when sourcing a replacement for the 1970 model specifically.
