An Unforeseen Problem With LED Traffic Lights
During a snowstorm last week, the Minnesota State Patrol responded to over 1,200 crashes and spinouts around the state. Fifty people were injured, and one woman was killed. Part of the problem, of course, was the slick roads. But there was another problem—an unexpected one. The state's Department of Transportation has been in the process of replacing the traditional incandescent traffic lights along state highways and roads with the much more energy efficient LED lights. The goal, of course, was to save money.
