Additional Notes

The Chevrolet Citation uses the 561 bulb for its dome light across the 1980-1983 model years.
The 561 is an ANSI-standardized bulb, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The 561 is a festoon-type bulb, which is a cylindrical form factor held in place by spring-loaded end caps rather than a screw base or bayonet mount.
The 561 bulb has a length of 44mm, which is the critical fitment factor for festoon bulbs, as the holder span must match the bulb length for proper contact.
Electrical ratings for the 561 are 12 volts and 12 watts, consistent with standard 12V automotive electrical systems.
Because festoon bulbs rely on end-cap contact rather than a keyed base, substitution with another festoon bulb is physically possible, but the 44mm length must be matched exactly to maintain secure contact within the dome light housing.
