Chevrolet Celebrity Parking Brake Indicator Bulb Size

Additional Notes

• The 194 bulb is the sole parking brake indicator bulb size listed for the Chevrolet Celebrity across all specified model years.
• The 194 designation follows the ANSI standard recognized in both the United States and Canada.
• It is a miniature wedge-type bulb, classified under the T10 form factor, which describes a tubular glass envelope approximately 10 millimeters wide at its widest point.
• The wedge base design means the bulb is held in its socket by the tension of the socket walls rather than by a bayonet or screw mechanism, making it a tool-free fitment in most applications.
• The 194 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
• Its rated wattage of 3.78W places it in the low-power category, typical of instrument panel and indicator lighting rather than exterior illumination.
• The 194 bulb size applies uniformly to the 1982-1990 model years covered in the specifications, with 1989 not represented among the listed entries.
• The T10 wedge format is widely used across many vehicle makes and models, meaning the 194 bulb is a broadly available replacement type rather than a proprietary part.
