Embedded in the road surface, they are an electronic improvement on the traditional cat's eyes. In that they may give drivers more than a thirty-second reaction window compared with about 3 seconds for conventional reflective devices. The intense brightness of the LED's makes them easily visible at distances of about 900 m under favourable conditions. Averaging about 100 mm square or 100 mm diameter and about 40 mm thick, units are extremely robust to avoid damage by passing vehicles, and are normally constructed of engineering plastics and poly carbonates. Use of solar road studs reduces the necessity of headlight main beams and the accompanying hazard of dazzling oncoming drivers. They are also more visible in rain and fog conditions where the old type retro reflectors and road markings are problematic. The solar cells charge batteries or capacitors during sunlit hours, over which period the flashing LEDs are turned off by a photo switch
