Additional Notes

The Chevrolet Chevy II uses two bulb types for the ignition light across its 1962-1968 model years: the 1445 and the 53.
Both the 1445 and the 53 are ANSI-standardized bulbs rated for use in the United States and Canada.
Each bulb is a single-filament type, meaning it serves one lighting function rather than combining two functions within a single unit.
Both bulbs share identical electrical ratings of 12 volts and 2 watts, placing them in the low-wattage indicator bulb category typical of instrument and warning light applications.
Both bulbs use a BA9s base, a miniature bayonet fitting with a 9mm collar and a single locating pin, which is a common base type in small indicator and panel lighting.
Despite their shared base type and identical voltage and wattage ratings, the 1445 and the 53 carry different ANSI designations, which can indicate differences in physical construction such as bulb envelope size or overall length.
The Chevrolet Chevy II (1964-1968) uses the 1445 bulb for the ignition light, while the 1962-1963 model years use the 53 bulb.
The shared BA9s base between the 1445 and the 53 does not by itself confirm interchangeability, as physical fit within the socket housing may differ between the two bulb types.
