Additional Notes

The bulb 73 is the most frequently specified size across the Chevrolet Camaro automatic transmission indicator fitments, covering model years 1993-2002. It is an ANSI-standard T5 miniature wedge bulb rated at 12V and 1.4W.
The bulb 194 is the second most common specification in these fitments, appearing across multiple model years from 1974-1977 and 1982-1989. It is an ANSI-standard T10 miniature wedge bulb rated at 12V and 3.78W.
Two distinct T5 wedge bulbs, the 73 and the 37, share the same physical form factor but differ in wattage. The 73 draws 1.4W while the 37 draws 1W, making them non-interchangeable despite their identical base type.
The T10 wedge form factor is shared by three different bulb sizes in these specifications: the 161 (1W), the 194 (3.78W), and the 168 (4.9W). Their wattage differences reflect distinct electrical load requirements, and they are not interchangeable.
The 1445 bulb, specified for the 1968-1969 Camaro, is the only single-filament bulb with a BA9s bayonet base in these fitments. This base type is physically incompatible with the wedge-base sockets used in all other listed model years.
The 1895 bulb, specified for the 1967 Camaro, is an ANSI-standard T5 miniature wedge type rated at 12V and 0.9W. It is the lowest-wattage bulb among all T5 wedge types listed in these specifications.
The 1893 bulb, specified for the 1981 Camaro, is a T5 miniature wedge type rated at 12V and 2W. Although it shares the T5 wedge form factor with the 73, 37, and 1895 bulbs, its wattage is distinct from all three.
The 161 bulb, used in the 1991-1992 Camaro, is a T10 miniature wedge type rated at 12V and 1W. It is the lowest-wattage T10 wedge bulb among those listed in these specifications.
