White and green are the most common colors in warning lights, followed by red. The white warning lights have high visibility and can effectively attract the attention of passers-by, but they cannot convey dangerous information. The green warning lights convey safety information, but they are not suitable for warning drivers of danger ahead.


The lights of police cars are red and blue, but the police lights in some countries have only one of the colors. Red is the primary color in the warm color system and has a warning effect, while blue is the primary color in the cool color system, which is in sharp contrast with red. It can attract people's attention.Police lights and sirens are used to warn pedestrians to give way so that the police can take action.
