What type of light must be used to show the license plate for a vehicle?

The requirement for a vehicle's license plate to be illuminated is specifically that it must be visible at night and under low-light conditions. The appropriate light for this purpose is white light. This is because white light provides the most clarity and visibility, ensuring that the characters on the license plate can be read easily from a distance.

In terms of regulations, many jurisdictions mandate that vehicle license plates must be lit with a white light to ensure compliance with lawful visibility standards. In contrast, other colors like red, blue, or amber would not be suitable for this function as they do not provide the level of visibility and clarity that white light does. Thus, using white light to illuminate a license plate meets both safety and legal requirements while promoting clear recognition of the vehicle's registration details.
