Additional Notes

The Chevrolet Corvair dome light uses the 211-2 bulb across all listed model years, spanning 1960-1969.
The 211-2 is a festoon-type bulb, meaning it is cylindrical in shape and mounts by pressing its end caps into spring clips rather than inserting into a socket.
The 211-2 has a length of 41mm, which is a critical fitment factor, as festoon bulbs must physically span the distance between the two contact clips in the housing.
The bulb uses an SV8.5 base, a designation that refers to the 8.5mm end cap width standard for festoon bulbs of this type.
The 211-2 operates at 12 volts and draws 12 watts, consistent with standard 12-volt automotive electrical systems.
The 211-2 carries ANSI standardization, meaning it conforms to a defined specification recognized in both the United States and Canada.
Because the 211-2 is an ANSI-standardized part number, bulbs from different manufacturers carrying the same designation are expected to share the same electrical and physical characteristics, supporting interchangeability within that standard.
Festoon bulbs of differing lengths are not interchangeable even when voltage and wattage ratings match, so the 41mm length of the 211-2 is a required specification for proper fitment in the Corvair dome light housing.
