Additional Notes

The Chevrolet Corvette ignition light bulb specifications span model years 1958 through 1968, covering three distinct bulb types across that period: the 1895, the 1445, and the 53.
The bulb 53 is the most frequently specified type in these records, appearing across six consecutive model years from 1958 to 1963.
The 53 bulb follows the ANSI standard for the US and Canada. It is a single-filament bulb with a BA9s bayonet base, rated at 12V and 2W.
The BA9s base is a miniature bayonet cap with a 9mm body, commonly associated with low-wattage indicator and instrument lighting applications.
The 1445 bulb shares the same electrical rating and base type as the 53, both operating at 12V and 2W with a BA9s base, which places them in the same general bulb family despite carrying different ANSI designations.
Because the 1445 and 53 share the same base type and electrical ratings, physical fitment between the two may be possible, though the differing ANSI designations indicate they are not officially interchangeable without verification of socket and housing compatibility.
The 1445 is specified for the Chevrolet Corvette across model years 1964 through 1967.
The 1895 bulb, specified for the 1968 model year, represents a departure from the BA9s base format. It is a T5 miniature wedge bulb, also rated at 12V but at a lower wattage of 0.9W, and it uses a wedge-style base rather than a bayonet fitting.
The wedge base of the 1895 is not compatible with the BA9s socket used by the 1445 and 53 bulbs, meaning the 1968 specification requires a physically distinct socket from those used in earlier model years.
All three bulb types conform to ANSI standards applicable to the US and Canadian markets.
