Chevrolet Citation Clock Light Bulb Size

Additional Notes

• The 194 bulb is the sole clock light bulb size listed for the Chevrolet Citation across the 1980-1983 model years.
• The 194 is an ANSI-standardized bulb, meaning its physical and electrical specifications are governed by a recognized North American standard applicable in both the United States and Canada.
• It belongs to the T10 miniature wedge family, a base type that relies on two angled plastic legs to secure the bulb directly into a socket without a separate metal base or locking ring.
• The bulb 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 range, appropriate for a small interior indicator application such as a clock backlight.
• Because the 194 is an ANSI-designated part number, it is produced by multiple manufacturers to the same specification, meaning physical and electrical interchangeability exists across compliant units bearing that designation.
• The T10 wedge format is widely used in instrument panel and interior lighting positions, so care is warranted to confirm socket fitment for the specific clock application rather than assuming compatibility based on bulb type alone.
