Additional Notes

The Chevrolet Chevy II uses two distinct bulb types for the engine compartment light across its 1962-1968 model years: the 1156 and the 94.
The 1156 is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base, and classified under the ANSI standard for the US and Canadian markets.
The 94 is a dual-filament bulb rated at 12V with a 21/5W output, fitted with a BAY15d bayonet base, and is also an ANSI-standard part for the US and Canadian markets.
The BAY15d base of the 94 bulb differs from the BA15s base of the 1156 in that it carries offset locating pins, which physically prevent the two bulbs from being interchanged despite their similar bayonet-style mounting.
The 94 bulb is a variant of the 1157, sharing its dual-filament design and BAY15d base, though it operates at different wattage levels than a standard 1157.
The Chevrolet Chevy II (1964-1968) uses the 1156 bulb for the engine compartment light, representing the majority of the model years covered in these specifications.
The 1962-1963 model years use the 94 bulb, which draws on both filaments at 21W and 5W respectively, a characteristic absent from the single-filament 1156 used in later years.
The transition from the 94 to the 1156 between the 1963 and 1964 model years reflects a change in both base type and filament configuration for this application.
