Additional Notes

The Chevrolet Laguna uses two festoon bulb types across its 1973-1976 model years for the dome light: the 211-2 and the 561.
Both the 211-2 and 561 are ANSI-standardized bulbs recognized in the United States and Canada, and both operate at 12 volts with a 12-watt output.
A festoon bulb is a cylindrical lamp that mounts horizontally between two contact points at either end of a housing, which is the standard configuration for automotive dome light fixtures.
The 211-2 bulb measures 41mm in length and uses an SV8.5 base, meaning its contacts are integrated into a single metal cap on one end of the bulb.
The 561 bulb measures 44mm in length and uses end-cap contacts, meaning bare metal contacts are exposed at both ends of the cylindrical body rather than through a single base.
The 3mm difference in length between the 211-2 and the 561 means the two bulbs are not directly interchangeable, as festoon fixtures are sized to hold a specific bulb length under spring tension.
The 1973 and 1976 Chevrolet Laguna share the 211-2 specification, while the 1974-1975 models use the 561.
The differing base designs of the two bulbs represent a further incompatibility beyond length, as the SV8.5 base of the 211-2 and the end-cap contacts of the 561 engage with their respective fixtures differently.
