Night Vision

The latest generation of 'cats eyes' SolarLite "smart stud" from pioneering British company Astucia uses stored solar power to run built-in Light Emitting Diodes (LEDs), providing an effective guide for drivers at up to 900 metres, extending reaction times from 3.2 seconds to over half a minute when driving at 60mph.
