Additional Notes

The 561 is the sole dome light bulb size listed across all Chevrolet Celebrity model years covered by these specifications, spanning 1982-1990.
The 561 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket.
Festoon bulbs are held in place by spring-loaded clips within the fixture, with the end caps pressing against the contacts to complete the circuit.
The 561 has a specified length of 44mm, which is a critical fitment factor, as festoon bulbs must physically span the distance between the two contact clips in the housing.
The bulb operates at 12 volts and draws 12 watts, consistent with standard automotive electrical systems.
The 561 carries ANSI designation, indicating it conforms to a standardized specification recognized in both the United States and Canada.
Because the 561 is an ANSI-standardized part, bulbs from different manufacturers carrying the same designation are expected to share the same electrical and physical characteristics, making cross-brand substitution generally straightforward.
The 1989 model year is not represented in these specifications, and no dome light bulb size is attributed to it here.
