Additional Notes

The instrument panel of the Chevrolet Celebrity uses two bulb types across its production years: the 194 and the 168, both of which are miniature wedge bulbs sharing the T10 form factor and operating on 12 volts.
The 194 bulb is rated at 3.78W, while the 168 bulb is rated at 4.9W. Despite their physical interchangeability as T10 wedge bulbs, the wattage difference means they are not electrically equivalent.
Both the 194 and 168 are defined under ANSI standards applicable in the United States and Canada, placing them within a standardized classification system for miniature automotive lighting.
The 194 bulb is the more frequently specified type for the Celebrity's instrument panel, appearing in the 1982, 1984, 1985, 1987, 1988, and 1990 model years.
The 168 bulb is specified for the 1983 and 1986 model years, representing a departure from the otherwise consistent use of the 194 across the model's production run.
Because the 194 and 168 share the T10 wedge base, a physical fit does not confirm correct specification. The wattage ratings differ, and substituting one for the other may affect instrument panel illumination output.
