Additional Notes

The Chevrolet Chevette uses two distinct parking light bulb sizes across its production run: the 1157 for model years 1976-1982 and the 2057 for model years 1983-1987.
Both the 1157 and 2057 are ANSI-standardized bulbs recognized in the United States and Canada, and both share the BAY15d bayonet base, a double-contact offset-pin base commonly used in automotive lighting.
Both bulbs are dual-filament types, meaning each contains two separate filaments within a single housing, one for a higher-intensity function and one for a lower-intensity function.
The 1157 operates at 12 volts with a power draw of 21W on the high filament and 5W on the low filament.
The 2057 also operates at 12 volts but draws 26.9W on the high filament and 8W on the low filament, making it the higher-output of the two bulb types used across the Chevette's production span.
Because the 1157 and 2057 share the same BAY15d base, the 2057 is physically interchangeable with the 1157 in terms of socket fitment, though the two differ in wattage output.
The 2057 is described as a brighter variant of the 1157, a distinction that reflects its higher filament wattage rather than any difference in base type or voltage rating.
The shift from the 1157 to the 2057 in the Chevrolet Chevette (1982 to 1983) represents a change in the specified bulb output for the parking light position, with the higher-wattage 2057 applied to the later production years.
