Additional Notes

The 194 bulb is the sole radio display bulb type listed for the Chevrolet Celebrity across all specified model years, covering 1982-1986.
The 194 bulb follows the ANSI standard, meaning it conforms to a defined North American specification recognized in both the United States and Canada.
It is classified as a miniature wedge bulb with a T10 form factor. The T10 designation refers to a tubular bulb body approximately 10 eighths of an inch wide, fitted with a wedge-style base that seats directly into a socket without a separate metal cap or pins.
The bulb operates at 12 volts, which is consistent with standard automotive electrical systems.
Its rated wattage is 3.78W, placing it in the low-power range typical of instrument and display illumination applications.
The wedge base design of the T10 means the bulb is held in place by the socket walls gripping the glass envelope directly, rather than by a bayonet or screw mechanism.
Because the 194 is an ANSI-standardized type, physically compatible substitutes from different manufacturers are generally expected to share the same voltage, wattage, and base configuration, provided they carry the same ANSI designation.
The consistent use of the 194 across the entire 1982-1986 production span indicates no bulb specification change occurred within that period for this application on the Celebrity.
