Besides, while fibre optic cable may be ideal to transmit light, is not very efficient at emitting it.
I do like your thinking however, Polly.
Perhaps streetlights could be set at a minimum illumination and have motion sensors which will turn them on to full untill 5min. after any motion has ceased.
