Additional Notes

The 2057 is the cornering bulb size for the Chevrolet Caprice across the 1991-1992 model years.
The 2057 follows the ANSI standard, meaning it meets the electrical and photometric requirements defined for the North American market, covering both the United States and Canada.
The 2057 is a dual-filament bulb, carrying two separate filaments within a single envelope. One filament operates at 26.9W and the other at 8W, allowing it to serve two distinct lighting functions at different intensities.
The 2057 uses a BAY15d bayonet base, a two-pin offset base design that physically prevents incorrect insertion by positioning the two pins at different heights along the base.
The 2057 is a brighter variant of the 1157 bulb. While both share the BAY15d base and dual-filament construction, the 2057 draws more wattage on its high-intensity filament, producing greater output.
Because the 2057 and 1157 share the same BAY15d base type, physical fitment between the two is possible, but their differing wattage ratings mean they are not fully interchangeable without accounting for the difference in output and electrical draw.
