Additional Notes

The 194 bulb is the license plate bulb size for the Chevrolet Impala Limited across the 2014-2016 model years.
The 194 bulb follows the ANSI standard, which is the American National Standards Institute classification system used to define bulb specifications in the United States and Canada.
It belongs to the T10 form factor, a miniature wedge-base bulb type that uses a tapering plastic base to secure itself in the socket without a separate metal base or locking mechanism.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
At 3.78 watts, the 194 draws a relatively low amount of power, which is typical for license plate lighting applications where output requirements are minimal.
The wedge base design of the T10 means that direct-fit LED replacements using the same wedge base are generally considered compatible at the socket level, though electrical behavior may differ from the original incandescent specification.
