Solar powered road studs offer 10-fold visibility improvement

November 21, 2007 As drivers we tend to ignore "cat's eyes" until we strike inclement weather or unfamiliar roads at night, at which point their safety value in showing us the road ahead comes very much to the fore. Standard reflective road studs rely on illumination from the headlight beams of the approaching vehicle and are effective to a distance of up to 90 meters, a situation that is being greatly improved by the application of solar power to the create stand-alone, self-powered illumination devices. The latest generation of solar road studs has just been announced by pioneering British company Astucia - the SolarLite™ “smart” road stud uses stored solar power to run built-in Light Emitting Diodes (LEDs), providing an effective guide for drivers at up to a distance of 900 meters and extending reaction times from 3.2 to over 30 seconds when driving at 60mph.
