Additional Notes

The 194 bulb is the license plate bulb size for the Chevrolet Citation across all listed model years, spanning 1980-1983.
The 194 bulb follows the ANSI standard, meaning it conforms to a specification recognized across the United States and Canada.
It is a miniature wedge-type bulb, classified under the T10 designation, which refers to its tubular form factor measured in eighths of an inch.
The wedge base design means the bulb is held in place by the socket gripping its glass envelope directly, with no separate metal base or pins involved.
The 194 operates at 12 volts, which is consistent with standard automotive electrical systems.
Its power draw is rated at 3.78 watts, placing it in the low-wattage range typical of auxiliary lighting functions such as license plate illumination.
Because the 194 bulb is an ANSI-standardized type, it is produced by multiple manufacturers, and physical fitment across compliant units is generally consistent.
The uniform fitment of the 194 across all four listed model years of the Citation indicates no mid-cycle change to the license plate lighting socket during that production span.
