Additional Notes

The Oldsmobile Cutlass Cruiser map light specifications cover model years 1980-1994, with five distinct bulb types used across that span.
The 906 bulb is the most frequently specified type, fitted to the Oldsmobile Cutlass Cruiser for the 1991-1994 model years. It is a T10 miniature wedge bulb rated at 12V and 8W, conforming to ANSI standards for the US and Canada.
The 561 bulb is the second most common type in these specifications, appearing across four model years: 1982, 1983, 1987, and 1989. It is a festoon bulb with a 44mm length and end-cap contacts, rated at 12V and 12W.
The 562 bulb, specified for the 1990 model year, shares the same festoon form factor, 44mm length, end-cap contacts, and 12V/12W rating as the 561. The two types are closely related and may be interchangeable in some applications, though fitment should be confirmed before substitution.
The 1004 bulb, used in the 1980-1981 model years, carries a BAY15d bayonet base and a dual-filament design rated at 12V with a 21/5W output. It is noted as a variant of the 1157 bulb family.
The 90 bulb, specified solely for the 1988 model year, uses a BA15s single-contact bayonet base and is rated at 12V and 13W. Its single-filament construction distinguishes it from the dual-filament 1004 used in adjacent earlier years.
The BA15s base of the 90 bulb and the BAY15d base of the 1004 bulb are physically similar but not interchangeable. The BAY15d base has offset pins to prevent incorrect installation of a single-filament bulb in a dual-filament socket.
The wedge base of the 906 and the end-cap contacts of the 561 and 562 represent fundamentally different mounting systems, meaning bulbs from those groups are not cross-compatible regardless of voltage or wattage similarities.
All five bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
The wattage across the specified bulbs ranges from 8W for the 906 up to 21W on the high filament of the 1004, reflecting variation in the power draw of the map light circuit across different model years of the Cutlass Cruiser.
