A Belisha beacon is a flashing orange globe atop a tall black and white pole. They appear on either side of the road at zebra crossings . They are named after Leslie Hore-Belisha (1895-1957), who introduced them in 1934

Their function is to provide additional visibility to zebra crossings for motorists, primarily at night. The light is normally powered by a simple bulb on a flashing circuit that runs until burnt out and requiring replacement. The flash commonly lasts one second in both on and off states.
