Additional Notes

The Chevrolet Chevette uses the 194 bulb for its turn signal indicator across all listed model years from 1976-1987.
The 194 is classified as a miniature wedge bulb under the T10 form factor, which refers to a tubular bulb body approximately 10mm wide at its widest point.
The 194 bulb operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of instrument and indicator applications.
The 194 conforms to ANSI standards recognized in both the United States and Canada, meaning it is produced to a consistent specification across North American markets.
The wedge base design of the T10 eliminates the need for a separate metal base or bayonet pins, as the glass envelope itself acts as the retention mechanism within the socket.
Because the 194 is an ANSI-standardized type, it is interchangeable with other bulbs sharing the T10 wedge base and the same voltage and wattage ratings, provided those substitutes meet the 12V, 3.78W specification.
The consistent use of a single bulb type across the entire 1976-1987 production span of the Chevette indicates no revision was made to the turn signal indicator circuit's bulb requirement during that period.
