Additional Notes

The 562 bulb is the sole map light bulb type listed for the Chevrolet Nova across the 1969-1970 model years.
The 562 is classified as a festoon bulb, a cylindrical form factor that seats between two spring-loaded end-cap contacts rather than inserting into a socket base.
The 562 operates at 12 volts and draws 12 watts, figures consistent with standard low-voltage interior automotive lighting of that era.
At 44mm in length, the 562 must seat correctly within a festoon holder of that specific span, as festoon bulbs are length-dependent for proper contact.
The 562 carries ANSI standardization recognized in both the United States and Canada, meaning the designation refers to a consistent specification across both markets.
