The Chevrolet Monte Carlo brake light utilizes 3057, 2057, and 1157 bulb sizes depending on the specific production era for the vehicle. Available data covers the period from 1970 through 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Monte Carlo uses three distinct brake bulb types across its production history: the 1157, 2057, and 3057 for the main brake lights, and either the 1156 or 891 for the center high mount stop light on applicable model years.
The 3057 is a dual-filament wedge bulb rated at 12V with a 27W high-filament and 7W low-filament draw. It fits the Monte Carlo's main brake light position for the 1995-2007 model years.
The 2057 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 26.9W high-filament and 8W low-filament draw. It serves the main brake light position on the 1983-1988 model years.
The 1157 is also a dual-filament BAY15d bayonet base bulb, rated at 12V with a 21W high-filament and 5W low-filament draw. It covers the main brake light position on the 1970-1982 model years.
Although the 2057 and 1157 share the same BAY15d bayonet base, they are not identical in output. The 2057 operates at a higher wattage on both filaments, making the two bulbs physically interchangeable in base fitment but electrically distinct.
The 3057 uses a wedge-style base rather than a bayonet base, which means it is not physically interchangeable with either the 1157 or the 2057 despite serving the same brake light function in later model years.
The center high mount stop light on the Monte Carlo uses single-filament bulbs exclusively, as this position requires only a stop signal with no secondary running-light function.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W. It fits the center high mount stop light on the 1986-1988 and 1998-2001 model years.
The 891 is a single-filament halogen bulb with a PGJ13 base, rated at 12V and 27W. It fits the center high mount stop light on the 1995-1997 Monte Carlo. The PGJ13 base is physically incompatible with the BA15s base used by the 1156, so the two bulbs are not interchangeable despite both serving the same position in adjacent model years.
All five bulb types listed in these specifications conform to ANSI standards applicable in both the United States and Canada.
