MNDOT replacing streetlights with more efficient LEDs

New­er, whit­er lights are one their way to Minnesota roads. The Minnesota Department of Transportation an­nounced a plan Mon­day to re­place more than 28,500 street­light bulbs with LED lights. Because they are more energy efficient and need replacing less often, the LEDs — short for light-emit­ting di­odes — will sup­pos­ed­ly save the state $1.45 mil­lion each year.
