Additional Notes

The Nissan 300ZX uses the 194 bulb for the license plate position across all listed model years, spanning 1984-1996.
The 194 is a T10 miniature wedge bulb, meaning it uses a wedge-style base rather than a bayonet or screw fitting, and is inserted directly into a friction-fit socket.
The 194 bulb operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs found in automotive lighting applications.
The 194 conforms to ANSI standards recognized in both the United States and Canada, indicating a standardized specification for the bulb's electrical and physical characteristics.
The T10 designation refers to the bulb's tubular envelope width, expressed in eighths of an inch, making the envelope 10/8 or 1.25 inches wide.
Because the 194 is an ANSI-standardized wedge type, it is cross-compatible with other bulb numbers sharing the same T10 wedge base and similar voltage ratings, though wattage differences among substitutes may affect brightness or socket fit.
