Additional Notes

The Chevrolet Lumina APV uses two bulb types across its dome light specifications: the 561 and the 562, both of which are festoon-style bulbs operating at 12 volts and 12 watts.
Festoon bulbs are cylindrical lamps that make electrical contact through metal caps at each end rather than through a base socket, which is a design common in interior automotive lighting applications.
Both the 561 and 562 are ANSI-standardized bulbs recognized in the United States and Canada, and both share a 44mm length with end-cap contacts.
Despite their near-identical physical and electrical specifications, the 561 and 562 carry distinct part numbers and are not confirmed as interchangeable within these specifications.
The 561 bulb is specified for the 1990, 1992-1994, and 1996 Lumina APV dome light positions.
The 562 bulb is specified for the 1991 and 1995 Lumina APV dome light positions.
The alternating use of the 561 and 562 across model years indicates that fitment is year-specific, and substituting one for the other without verification of compatibility is not supported by these specifications.
The 561 is the more frequently specified bulb across the Lumina APV model range, covering five of the seven model years listed.
