The Chevrolet S10 brake light utilizes 1157, 2057, and 3057 bulb sizes depending on the specific version of the vehicle. Available data covers a range from 1982 through 2004 for the components listed.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet S10 brake light specifications cover model years 1982 through 2004, with three distinct bulb types used across that span: the 1157, 2057, and 3057.
The 1157 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with filaments drawing 21W and 5W respectively. It follows the ANSI standard applicable in both the US and Canada.
The 2057 shares the same BAY15d bayonet base as the 1157 and operates at 12V, but its filaments are rated at 26.9W and 8W, making it a higher-output variant of the 1157 type.
The 3057 is a dual-filament wedge bulb of the T25 form factor, rated at 12V with filaments at 27W and 7W. Unlike the 1157 and 2057, it does not use a bayonet base, which makes it physically incompatible with sockets designed for those types.
The Chevrolet S10 used the 1157 for brake lights from 1982 through 1990, the 2057 from 1991 through 1993, and the 3057 from 1994 through 1998 and again in 2004.
Because the 1157 and 2057 share the BAY15d bayonet base, they are physically interchangeable in terms of socket fitment, though their wattage ratings differ between the two types.
The 3057 uses a wedge-style base rather than a bayonet mount, meaning it is not a drop-in substitute for either the 1157 or the 2057 without a corresponding socket change.
The center high mount stop light on the S10 uses the 211-2, a festoon-type bulb with an SV8.5 base and a 41mm length, rated at 12V and 12W. This single-filament bulb serves a dedicated stop light function separate from the main brake light circuit.
The 211-2 festoon format is physically distinct from all three of the main brake light bulb types, as it mounts between two end caps rather than into a bayonet or wedge socket.
All four bulb types listed in the S10 brake light specifications conform to ANSI standards recognized in both the US and Canada.
