Art Lebedev Studios get paid to do nothing but conjure up ideas, because this one is just marvelous. And marvelously simple, but that's beside the point. The Luxofor traffic light concept improves upon a nearly archaic design that still relies on spherical fixtures when there's really no need. Lebedev's team asserts that using square lights backed with bright laser diodes would make better use of the available space and provide a more noticeable signal to drowsy motorists. The roar of "why didn't I think of that?" being simultaneously stated is downright deafening.
