Additional Notes

The Chevrolet Cavalier parking brake indicator uses two bulb sizes across its model years: the 194 for 1982-1993 and the 161 for 1994.
Both the 161 and 194 are ANSI-standardized miniature wedge bulbs sharing the T10 form factor and a 12-volt operating voltage, which means they are physically interchangeable in terms of socket fitment.
Despite sharing the same T10 wedge base, the 161 and 194 differ in wattage. The 161 draws 1W, while the 194 draws 3.78W, making them electrically distinct.
The wattage difference between the two bulbs means that substituting one for the other may affect indicator brightness and could place unintended load on the vehicle's instrument lighting circuit.
The 194 bulb is the predominant specification for the Cavalier's parking brake indicator, covering twelve of the thirteen model years represented in the data.
