The Oldsmobile Aurora brake light requires a 3057 bulb size for proper installation and function within the rear lighting assembly. Data provided for the bulb specifications covers the range from 1995 to 2003.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Oldsmobile Aurora uses the 3057 bulb for brake lighting across all specified model years, spanning 1995-1999 and 2001-2003.
The 3057 is a dual-filament wedge bulb of the T25 type, rated at 12 volts with a wattage split of 27W for the high-intensity filament and 7W for the low-intensity filament, conforming to ANSI standards recognized in both the United States and Canada.
The dual-filament design of the 3057 allows a single bulb to serve both a running light function at lower wattage and a brake light function at higher wattage.
The center high mount stop light on the Oldsmobile Aurora uses the 1156 bulb for model years 1995-1999.
The 1156 is a single-filament bulb rated at 12 volts and 21W, fitted with a BA15s bayonet base, and also conforms to ANSI standards for the United States and Canada.
The BA15s bayonet base of the 1156 is not interchangeable with the wedge-style base of the 3057, making the two bulb types physically incompatible with each other's sockets.
The 3057 and 1156 also differ in filament count, with the 3057 carrying two filaments and the 1156 carrying one, which further distinguishes their respective circuit roles.
For the 2000 model year of the Oldsmobile Aurora, no brake bulb data is present in the specifications for either the standard brake lights or the center high mount stop light.
The center high mount stop light specification covers only 1995-1999, while the standard brake bulb specification extends through 2003, reflecting a difference in the range of data provided for each lighting position.
