Additional Notes

The 561 bulb is the most frequently specified dome light bulb across the Oldsmobile Cutlass Supreme model years covered, appearing in 1967 through 1997 across a greater number of years than any other bulb type in these specifications.
The 561 is a festoon-type bulb rated at 12V and 12W, with a 44mm length and end-cap contacts, conforming to the ANSI standard for the US and Canadian markets.
The 562 bulb shares the same 44mm length, end-cap contact design, 12V rating, and 12W output as the 561, making the two physically and electrically similar festoon types.
Despite their similarities, the 561 and 562 are distinct part numbers and are not listed interchangeably within these specifications; the 1983, 1985, and 1990 model years each call specifically for the 562.
The 211-2 and 212-2 are both 41mm festoon bulbs with an SV8.5 base, rated at 12V and 12W, and both conform to the ANSI standard. The SV8.5 base uses a different mounting style than the end-cap contacts found on the 561 and 562.
Because the 211-2 and 212-2 use an SV8.5 base while the 561 and 562 use end-cap contacts, these two groups are not physically interchangeable despite sharing the same voltage and wattage ratings.
The 212-2 is specified for the Oldsmobile Cutlass Supreme dome light in 1972, 1974, 1977, and 1991-1994, while the 211-2 covers 1967-1970, 1973, 1978-1979, and 1981.
The 161 is the only miniature wedge bulb (T10 type) in these specifications, rated at 12V and 1W, which is a substantially lower wattage than all other bulb types listed. It is specified solely for the 1971 model year.
The low 1W output of the 161 bulb contrasts sharply with the 12W output of the festoon types, meaning a substitution between the 161 and any festoon bulb would result in a significant difference in light output and current draw.
All five bulb types in these specifications conform to ANSI standards applicable to both the United States and Canada, indicating standardized electrical and physical tolerances across the range.
