White Warning Lights Urged for Police

White Warning Lights Urged for Police

The traditional flashing red light atop police cars may be joined by white lights if recommendations of government scientists are adopted. This development is featured in the September issue of Dimensions/ NBS, the monthly magazine of the National Bureau of Standards.

In an article on “Greater Visibility Sought for Warning Lights,” the publication reports on NBS research to make warning signals, such as lights on police cars, more visible and more easily recognizable.

In its studies, the magazine states, NBS found white light to be the most visible and recommended it as an “essential” part of a warning system for police vehicles.

Guidelines for emergency lights set forth by the bureau specify that they should be readily noticeable under all conditions, clearly understandable, compatible with the environment, easy to use, reliable and of low cost—both in dollars and energy demand.
