Sad to read of the report from a German university that suggests that led lights have done nothing to darken the night sky but made it worse.there was a picture, from a space craft,of Doha Qatar, a place I've been once(nice dragonflies!) .you can see from the lit roads connecting Doha with other towns how much light bounces back,a lot!lighting uninhabited roads is a big problem and defeats the reasoning behind cars having their own lights on them!lit rural roads must increase speed and therefore the accident rate?
