Additional Notes

The Chevrolet Bel Air uses the 562 bulb for the map light across all listed model years, spanning 1962-1970.
The 562 is a festoon-type bulb, meaning it is cylindrical in shape with metal end-cap contacts at each end rather than a base socket, and it seats by pressing lengthwise into spring-loaded clips.
The 562 bulb has a total length of 44mm, which is the critical fitment factor when considering any equivalent or replacement unit.
It operates at 12 volts and draws 12 watts, placing it in the range typical of interior courtesy and reading lamp applications.
The 562 carries ANSI standardization recognized in both the United States and Canada, meaning the designation refers to a consistent, defined specification rather than a proprietary part number.
Because festoon bulbs are sized by length and contact type, substituting a festoon bulb of a different length, such as 31mm or 36mm units, would result in an improper fit even if the voltage rating matches.
