Additional Notes

The Chevrolet Cavalier high beam indicator uses three distinct bulb types across its model years: the PC74, the 194, and the 161, all of which conform to ANSI standards applicable in the United States and Canada.
The 194 is the most frequently specified bulb across the Cavalier's high beam indicator fitments, appearing in the 1982-1985 and 1987-1994 model years.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, making it the highest-wattage option among the three bulb types listed in these specifications.
The PC74 is specified for the 2000-2002 Chevrolet Cavalier and differs fundamentally from the other two bulb types in its socket design, using a printed circuit board twist-lock mount rather than a standard wedge base.
The PC74 is a T5 miniature wedge bulb rated at 12V and 1.4W, and its printed circuit board socket makes it physically incompatible with sockets designed for T10 wedge bulbs such as the 194 or 161.
The 161 is a T10 miniature wedge bulb rated at 12V and 1W, and while it shares the same T10 wedge form factor as the 194, its wattage is significantly lower, which means the two are not interchangeable without accounting for that difference.
The 161 is specified exclusively for the 1986 Cavalier, making it an isolated fitment within these specifications and distinct from the surrounding model years that use the 194.
