Additional Notes

The Chevrolet C60 uses the 1157 bulb for its parking light across all listed model years, spanning 1960-1988.
The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single housing, one rated at 21 watts and the other at 5 watts.
The bulb operates on a 12-volt electrical system, which is standard for automotive applications in this class of vehicle.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect installation by ensuring the bulb can only be seated in one orientation.
The 1157 conforms to ANSI standards and is recognized across both the United States and Canada, reflecting a standardized specification shared across North American markets.
Because the BAY15d base is offset, it is not interchangeable with single-pin or symmetrical bayonet bases, and substituting a physically similar but differently pinned bulb would result in an improper fit.
