The Oldsmobile Cutlass Ciera brake light requires a 1157 bulb size for proper installation and function within the lighting assembly. Data for the specified component covers the period from 1982 through 1990.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Oldsmobile Cutlass Ciera uses the 1157 bulb for its brake lights across all listed model years, spanning 1982-1990.
The 1157 is a dual-filament bulb rated at 12V with a 21W/5W output, mounted on a BAY15d bayonet base, which allows it to serve both stop and tail light functions through its two filaments.
The BAY15d base features offset pins, a design that prevents incorrect installation by ensuring the bulb can only be seated in one orientation.
The center high mount stop light on the Cutlass Ciera does not use a single bulb type across all listed years, with the 1987-1990 and 1985-1986 entries specifying the 1156, while 1988-1989 specify the 2355.
The 1156 is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base, making it electrically and physically distinct from the dual-filament 1157 used in the standard brake light positions.
The 2355 is also a dual-filament bulb on a BAY15d bayonet base rated at 12V, sharing its base type with the 1157, though the two are not confirmed interchangeable due to differences in wattage ratings and filament configuration.
Because the 1156 uses a BA15s single-pin base and the 1157 uses a BAY15d dual-pin base, these two bulb types are not physically interchangeable despite their similar appearance.
The shared BAY15d base between the 1157 and 2355 means physical fitment may be possible between the two, but wattage differences make substitution a matter requiring verification against the vehicle's socket and circuit specifications.
All three bulb types listed in these specifications conform to ANSI standards applicable in both the United States and Canada.
