Additional Notes

The Chevrolet Corsica engine compartment light uses two distinct festoon bulb types across its production run: the 211-2 and the 561.
Both the 211-2 and 561 are ANSI-standard festoon bulbs rated at 12V and 12W, meaning they share identical electrical characteristics.
A festoon bulb is a cylindrical lamp that mounts horizontally between two contact points at either end, a common format for enclosed compartment lighting.
The 211-2 measures 41mm in length and uses an SV8.5 base, which features a metal sleeve around the glass envelope that makes contact with the socket.
The 561 measures 44mm in length and uses end-cap contacts, meaning bare metal caps at each end of the bulb make direct contact with the socket clips.
The 3mm difference in length between the 211-2 and the 561, combined with their different base types, means the two bulbs are not interchangeable despite their identical voltage and wattage ratings.
The 1987-1989 Corsica specifies the 561 bulb for the engine compartment light position.
The 1991 Corsica (Chevrolet Corsica) specifies the 211-2 bulb, reflecting a change in socket design from the earlier model years.
