Additional Notes

The 211-2 is the sole dome light bulb type listed across all Chevrolet Chevy II model years covered by these specifications, spanning 1962-1968.
The 211-2 is a festoon-style 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 carries an SV8.5 base designation, which refers to the metal end cap contact points characteristic of festoon bulbs in this size class.
The bulb has a physical length of 41mm, a measurement that governs fitment within the dome light housing.
The 211-2 operates at 12 volts and 12 watts, consistent with standard 12-volt automotive electrical systems of the era.
The 211-2 conforms to ANSI standards recognized in both the United States and Canada, indicating a standardized specification rather than a proprietary part.
Because the 211-2 is a festoon type, substituting a bulb of a different length risks poor contact with the spring clips, even if the wattage and voltage ratings otherwise match.
