What color is required for the license plate lamp?

The license plate lamp is required to be clear or white because this color provides the best visibility and ensures that the license plate is legible under various lighting conditions. A clear or white light illuminates the entire area of the license plate without distorting visibility, allowing law enforcement and other drivers to read the plate easily at night or in poor weather conditions. This requirement is in accordance with regulations that aim to ensure safety and visibility for vehicles on the road.

Other colors, such as red, amber, or yellow, do not serve the purpose of adequately illuminating a license plate because they can obstruct readability. For instance, red lights may be associated with tail lights, and amber lights are often used for turn signals or hazard lights, which could lead to confusion for other drivers. Thus, the standardization of clear or white for license plate lamps enhances overall road safety and compliance with traffic laws.
