Additional Notes

The 194 bulb is the license plate bulb size for the Toyota GR Corolla across the 2023-2024 model years.
The 194 bulb follows the ANSI standard recognized in the United States and Canada, classifying it as a regionally standardized automotive lighting component.
It is a T10 miniature wedge bulb, a form factor defined by its wedge-shaped base, which allows direct insertion into a compatible socket without a separate metal base or pins.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
Its rated wattage of 3.78W places it in the low-power category, typical for non-illumination roles such as license plate lighting.
The T10 wedge form factor is widely shared across many vehicle applications, though fitment compatibility depends on the specific socket design of each vehicle.
