Additional Notes

The Ford B-600 instrument panel draws from six distinct ANSI-standard bulb sizes across the 1980-1994 model range: 194, 161, 1445, 1816, 1892, and 1895.
The 194 bulb is the most frequently specified type in the Ford B-600 instrument panel, covering model years 1980-1984, 1987, and 1989. It is a T10 miniature wedge bulb rated at 12V and 3.78W.
The 161 bulb, used in the 1985-1986 model years, shares the T10 wedge form factor with the 194 but operates at a significantly lower wattage of 1W versus 3.78W, making the two electrically incompatible despite their physical similarity.
The 1892 bulb, specified for 1991-1992, is a T5 miniature wedge type rated at 12V and 3W. The 1895 bulb, used in 1988, also carries a T5 form factor but is rated at only 0.9W, meaning the two are not interchangeable despite sharing the same envelope shape.
The 1445 bulb, specified for 1993-1994, is the only bulb in this set that uses a BA9s bayonet base rather than a wedge base. This base type difference makes it physically incompatible with all other bulb sizes listed for the Ford B-600 instrument panel.
The 1816 bulb, used in the 1990 model year, is a T3.25 miniature wedge type rated at 12V and 4W, giving it the highest wattage of any bulb specified across the entire 1980-1994 range for this application.
All six bulb types in these specifications conform to ANSI standards recognized in both the United States and Canada, indicating consistent regulatory compliance across the full model range.
The wedge base design, present in five of the six bulb types, allows for tool-free removal by pulling the bulb directly from its socket, a common characteristic of miniature wedge bulbs used in instrument panel applications.
