Additional Notes

The 194 bulb is the sole clock light bulb size specified for the Chevrolet Celebrity, covering both 1982 and 1985.
The 194 is classified as an ANSI-standard miniature wedge bulb, recognized across the United States and Canada under a shared standardization framework.
The T10 designation refers to the bulb's tubular envelope, with the numeric portion indicating a width of ten-eighths of an inch, a sizing convention standard to the miniature wedge family.
The 194 operates at 12 volts and draws 3.78 watts, consistent with low-current interior indicator and illumination applications.
The wedge base design of the 194 relies on the bulb's glass envelope and wire leads to form the electrical connection, eliminating a separate metal base and allowing direct insertion into compatible sockets.
ANSI standardization of the 194 means the bulb's electrical and physical characteristics conform to a defined specification, which supports interchangeability across different manufacturers producing bulbs under the same designation.
