Additional Notes

The Chevrolet Blazer ash tray position uses three distinct bulb types across its model years: the 194, 161, and 1445.
The 194 and 161 are both T10 miniature wedge bulbs operating at 12V, which means they share the same physical base type. However, their wattage differs significantly, with the 194 rated at 3.78W and the 161 rated at 1W, making them non-interchangeable despite the shared form factor.
The 1445 bulb uses a BA9s bayonet-style base rather than a wedge fitting, which is physically incompatible with the T10 socket used by the 194 and 161 bulbs.
The Chevrolet Blazer (1969-1972) uses the 1445 bulb, which operates at 12V and 2W with a BA9s base.
Model years 1989-1991 and 1993-1994 share the 194 specification for the ash tray position, as do the 2000-2003 model years.
The 161 bulb was fitted to the Blazer ash tray position across the 1995-1999 model years.
All three bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
The shift from the 194 to the 161 between the 1994 and 1995 model years represents a reduction in wattage from 3.78W to 1W within the same T10 wedge socket format.
