Additional Notes

The Chevrolet Corsica uses the 194 bulb for the license plate position across all listed model years, spanning 1987-1996.
The 194 is a miniature wedge-type bulb, classified under the T10 form factor, which refers to a tubular bulb body roughly 10 eighths of an inch wide.
The wedge base design means the bulb is held in place by the socket gripping the glass envelope directly, with no separate metal base or pins involved.
The 194 operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs used in automotive exterior lighting.
The 194 conforms to ANSI standards recognized in both the United States and Canada, indicating a standardized specification for physical size and electrical output.
The T10 wedge format is shared by several bulb numbers in the miniature wedge family, though wattage and voltage ratings differ between them, making cross-substitution dependent on matching the electrical specifications rather than the physical form alone.
Because the 194 is an ANSI-standardized type, aftermarket and OEM replacements from different manufacturers are generally interchangeable as long as they carry the same bulb number designation.
