Switch to LEDs has lightened load for Champaign's traffic and lighting workers

Like many homeowners, the city of Champaign doesn't have to spend as much time changing light bulbs as it used to. Champaign's traffic lights have gradually been moving toward LED lights, said Kris Koester, spokesman for the public works department. "Since switching to LED lights a few years ago, there are less occurrences of lights being completely out," he said. And the lights mostly run by themselves according to schedules pre-programmed into the electrical cabinet at most intersections.
