Additional Notes

The Chevrolet Beretta map light specifications span the full production run of the model, from 1987 through 1994, and reference four distinct bulb types across those years: 906, 561, 192, and 212-2.
The 906 bulb, used in the 1987-1989 Beretta, is a miniature wedge type in the T10 form factor, rated at 12V and 8W, and conforms to the ANSI standard applicable in both the United States and Canada.
The 561 bulb, specified for the 1990 model year, is a festoon type with end-cap contacts and a 44mm length, also rated at 12V and 12W under the same ANSI standard.
The 192 bulb, covering the 1991-1993 model years, is a miniature wedge type in the T10 form factor rated at 12V and 3W, making it significantly lower in wattage than the 906 despite sharing the same physical form factor.
Because the 192 and 906 bulbs share the T10 wedge form factor, they are physically interchangeable in the socket, but their wattage ratings differ substantially at 3W and 8W respectively, meaning substitution between them is not electrically equivalent.
The 212-2 bulb, specified for the 1994 model year, is a festoon type with an SV8.5 base and a 41mm length, rated at 12V and 12W.
The two festoon bulbs in these specifications, the 561 and the 212-2, share the same voltage and wattage ratings but differ in length and base type, with the 561 measuring 44mm with end-cap contacts and the 212-2 measuring 41mm with an SV8.5 base, making them non-interchangeable.
All four bulb types referenced in these specifications conform to ANSI standards recognized in both the United States and Canada, and all operate on a 12V electrical system.
