Additional Notes

The Chevrolet B60 high beam indicator uses two distinct bulb types across the 1980-1991 model years: the 194 and the 1445, both of which conform to ANSI standards recognized in the United States and Canada.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W. Its wedge base design means it is held in place by the socket itself rather than by a separate metal base or locking mechanism.
The 1445 is a single-filament bulb with a BA9s bayonet cap base, rated at 12V and 2W. The BA9s base uses a small bayonet fitting with a 9mm cap width, which is physically incompatible with the wedge socket used by the 194.
Because the 194 and 1445 use different base types, the two bulbs are not interchangeable. Installing the wrong type requires a socket that does not match the bulb's base, making direct substitution between them impossible without modification.
The 194 draws 3.78W while the 1445 draws 2W. This difference in wattage reflects a meaningful gap in power consumption between the two bulb types used across different model years.
The 1445 was specified for the Chevrolet B60 in 1980-1982, 1984, and 1986. The 194 was specified in 1983, 1985, and 1987-1991, making it the more frequently specified of the two bulb types across this range.
The alternating pattern of bulb specifications across certain years, such as 1984 using the 1445 and 1985 using the 194, indicates that the socket type in the instrument cluster was not consistent across all production years and should be confirmed before sourcing a replacement.
