Additional Notes

The Buick Skyhawk uses the 194 bulb for its license plate position across all model years listed in the specifications, spanning 1975-1989.
The 194 is classified as a miniature wedge bulb, designated T10 in the international bulb sizing system, where "T" refers to the tubular shape and "10" indicates the width in eighths of an inch.
The 194 bulb operates at 12 volts with a power draw of 3.78 watts, placing it among the lower-wattage bulbs in the miniature automotive category.
The 194 carries ANSI standardization, meaning its physical and electrical specifications are governed by a recognized industry standard applicable in both the United States and Canada.
The wedge base design of the 194 means the bulb is held in its socket by the tension of the base itself rather than by a separate bayonet or screw mechanism, which is a common trait in license plate and interior lighting applications.
Because the 194 is an ANSI-standardized T10 wedge type, it is interchangeable with other bulbs sharing the same base and voltage rating, provided the wattage and physical fit are compatible with the Skyhawk's socket.
