    They got a bad rap up here in the North where we get snow. Blowing snow would often coat the lenses of traffic signals. Incandescents generated enough heat to just melt the snow, but LED replacement lamps would not and people could no longer see some of the signals. They now have thermostat-controlled heaters to solve the problem, but it made many cities gunshy.
