Additional Notes

The Chevrolet Corvair uses two bulb types for the turn signal indicator across its 1960-1969 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 envelope.
Both bulbs share identical electrical ratings of 12 volts and 2 watts, placing them in the low-wattage range typical of indicator and warning light applications.
The 1445 and the 53 both use a BA9s base, a miniature bayonet fitting with a 9mm collar that is common in small indicator bulb sockets.
Despite sharing the same base type, voltage, wattage, and ANSI classification category, the 1445 and the 53 carry distinct part numbers, which indicates a physical difference that affects fitment.
The Chevrolet Corvair (1965-1969) uses the 1445 bulb for the turn signal indicator position.
The 1960-1964 model years use the 53 bulb in the same position, representing a specification change at the 1965 model year.
