My idea is....
At an average of ten hours of usage per day, a single 500W overhead street light consumes 5kw-hrs of electricity.At a nominal 4 cents/kwh, that means it's about 20 cents a day per streetlight, or -$60/year in electicity alone ( not counting replacement or instillation costs )In urban areas we want the lights for many reasons , but in suburban or highway areas the lights are used solely to illuminate the roadway for safe driving.

Why not use glow-in-the-dark phosphor inside the paint used for the white and yellow lines on all roads ? This would dramatically increase visibility ,substantially increase safetyand draw power from ambient sunlight.This latter means we eliminate the electricity drain and maintenance ,as well as bring illumination to more rural areas where running power for overhead lights is impractical
