Additional Notes

The 1004 bulb is the most frequently specified map light bulb across the Oldsmobile Cutlass Salon lineup, appearing in the 1976-1980 model years.
The 1004 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V and 21/5W, and is classified as a variant of the widely known 1157 bulb type.
A BAY15d bayonet base features two offset pins at different heights, which physically prevents incorrect installation of single-filament bulbs into a dual-filament socket.
The 1987 Oldsmobile Cutlass Salon uses a 906 bulb for the map light, a T10 miniature wedge type rated at 12V and 8W under the ANSI standard.
The T10 wedge base of the 906 bulb relies on the bulb's glass envelope and metal contacts to seat directly into the socket, with no separate base pins or caps.
The 1986 Oldsmobile Cutlass Salon uses a 562 festoon bulb, which is 44mm in length and makes contact through metal end caps at each end rather than a base socket.
At 12V and 12W, the 562 festoon bulb carries a higher wattage than the 906 wedge bulb used in the 1987 model year.
All three bulb types, the 1004, 906, and 562, conform to ANSI standards applicable in both the United States and Canada.
The three bulb types specified across these model years use three distinct base configurations, a bayonet base, a wedge base, and end-cap contacts, making them physically non-interchangeable with one another.
Each of the three bulb types operates at 12V, consistent with standard automotive electrical systems.
