Additional Notes

The 561 is the most frequently specified dome light bulb for the Oldsmobile Cutlass Cruiser, appearing across ten of the twelve model years listed, spanning 1980-1994 with isolated exceptions in 1987 and 1990.
The 561 is a festoon-type bulb, meaning it mounts horizontally between two end-cap contacts rather than using a bayonet or wedge base. It measures 44mm in length and operates at 12V with a 12W output.
The 211-2, specified for the 1981 model year, is also a festoon bulb and shares the same 12V, 12W electrical rating as the 561, but its physical length is 41mm and it uses an SV8.5 base rather than plain end-cap contacts.
Because the 561 and 211-2 differ in both length and base type, they are not directly interchangeable despite sharing identical voltage and wattage ratings.
The 1987 Cutlass Cruiser uses the 906, a T10 miniature wedge bulb rated at 12V and 8W. Its wedge base design is physically incompatible with the festoon sockets used in other model years.
The 1990 Cutlass Cruiser uses the 90, a single-filament bulb with a BA15s bayonet base rated at 12V and 13W. The bayonet mounting mechanism distinguishes it from all other bulb types listed for this model.
All four bulb types across these specifications conform to ANSI standards applicable in both the United States and Canada.
The 1987 and 1990 model years each use a bulb with a wattage that differs from the 12W rating shared by the festoon types, with the 906 drawing less power at 8W and the 90 drawing slightly more at 13W.
