Additional Notes

The Chevrolet Citation uses the 194 bulb for the parking brake indicator across all listed model years, spanning 1980-1983.
The 194 is classified as a miniature wedge bulb under the T10 form factor, which refers to a tubular glass envelope roughly 10 millimeters wide with a wedge-style base that connects directly to the socket without a separate metal base or pins.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of instrument panel and warning indicator applications.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning the specification is consistent across North American markets rather than being a regional variant.
The wedge base design of the 194 means the bulb is held in place by the socket's contact tension rather than a bayonet or screw mechanism, which affects how the bulb is seated and removed during replacement.
Because the 194 is an ANSI-standardized type, bulbs carrying that designation from different manufacturers are generally interchangeable as long as the voltage, wattage, and base type match the specification.
