MDU is preparing to make a switch in streetlights.
Over the next year or so, MDU is planning to replace the halogen lights with LED lights.
"They're more efficient and cost effective," said MDU spokesman Mark Hanson.
Hanson did say it is an expensive switch.
"That means the rent amount to each city will go up dramatically," Hanson said. "But the energy savings will reduce that cost dramtically."
