The Chevrolet Corsica brake light utilizes a 2057 bulb size for illumination across all available vehicle configurations within the provided technical data set. Information provided covers a span from 1987 through 1996 for the specified automotive lighting component.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Corsica uses two distinct brake bulb types across its production run: the 2057 for the standard brake lights and the 1156 for the Center High Mount Stop Light.
Both bulb assignments remain consistent across the entire 1987-1996 model range, with no variation by year for either position.
The 2057 is a dual-filament bulb operating at 12V with a wattage split of 26.9W on the high-intensity filament and 8W on the low-intensity filament, making it suitable for combined stop and tail light functions.
The 2057 uses a BAY15d bayonet base, which is an offset two-pin base designed to prevent incorrect installation by ensuring the bulb can only be seated in one orientation.
The 1156 is a single-filament bulb rated at 12V and 21W, reflecting its dedicated stop light role in the Center High Mount Stop Light position, which requires no secondary tail light function.
The 1156 uses a BA15s bayonet base, a single-pin base that is not interchangeable with the BAY15d base of the 2057, despite both being bayonet-style fittings.
The 2057 is described as a brighter variant of the 1157, sharing the same BAY15d base and dual-filament design but drawing higher wattage on the primary filament.
Both the 2057 and 1156 conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and photometric performance requirements for both bulbs.
