Additional Notes

The Chevrolet Corsica dome light specifications span the 1987-1996 model years and reference four distinct bulb types: 561, 562, 192, and 194.
The 561 and 562 are both festoon-type bulbs with 44mm length and end-cap contacts, operating at 12V and 12W. Their shared physical format and electrical ratings make them closely related, though they carry different ANSI designations.
Despite their near-identical specifications, the 561 and 562 are listed as separate part numbers under ANSI standards for both the US and Canadian markets, and fitment should follow the year-specific data rather than assuming interchangeability between the two.
The 192 and 194 are both T10 miniature wedge bulbs operating at 12V, but they differ in wattage. The 192 is rated at 3W, while the 194 draws 3.78W. This difference means the two are not confirmed as interchangeable within these specifications.
The Chevrolet Corsica (1987-1990) used the 561 festoon bulb for the dome light across four consecutive model years, representing the longest uninterrupted run of a single bulb type in this dataset.
The 1991 model year is the only year in the dataset specifying the 192 wedge bulb, and the 1995 model year is the only year specifying the 194 wedge bulb. Both represent isolated single-year fitments within the Corsica's production run.
The 1992 model year marks a transition from the 561 to the 561's close relative, the 562, though the 562 does not appear again until 1993 and 1994, with 1996 also carrying the 562 designation.
All four bulb types in the specifications conform to ANSI standards recognized in both the United States and Canada, indicating consistent regulatory compliance across the Corsica's dome light fitments.
The festoon bulb format used by the 561 and 562 relies on end-cap contacts rather than a wedge base, meaning the socket design in the years specifying festoon bulbs is physically incompatible with the wedge-base sockets required by the 192 and 194.
The wattage difference between the festoon bulbs (12W) and the wedge bulbs (3W or 3.78W) reflects a significant gap in power draw, which corresponds to differences in brightness output between the dome light configurations used across the Corsica's model years.
