Northern Indiana Public Service Company's says it plans to add light-emitting diode, or LED, lights to 42,000 streetlights by the year 2022.
The (Northwest Indiana) Times reports that about 7,200 streetlights will be upgraded this year in East Chicago, Hebron, Highland, Kouts, Munster, Schererville, Valparaiso, Wheatfield and Whiting.
NIPSCO previously had a pilot program to replace the streetlights and last year started replacing all of its old fixtures with LED lighting.
