Additional Notes

The 194 bulb is the sole license plate bulb size listed for the Pontiac J2000, covering the 1982-1983 model years.
The 194 is an ANSI-standard bulb recognized in both the United States and Canada, classifying it as a widely standardized automotive component.
It follows the T10 miniature wedge form factor, a base type that uses a wedge-shaped plastic housing in place of a metal pin or bayonet base to secure the bulb in its socket.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage of 3.78W places it in the low-power range, which is typical for license plate illumination applications where minimal heat output and low current draw are expected.
The wedge base design of the T10 means the bulb is held in place by the tension of the socket contacts rather than a locking mechanism, making direct substitution dependent on socket compatibility rather than a separate base fitting.
