Detroit’s LED streetlights going dark after a few years

The city's lighting authority fears tens of thousands of streetlights are in jeopardy of failing just a few years after being installed, threatening to put some of Detroit's neighborhoods back into the dark. The authority behind the state-of-the-art overhaul of Detroit's streetlight system filed a federal lawsuit Monday against the manufacturer of nearly a third of the city's 65,000 streetlights, saying a fix is expected to cost millions.
