Sharp's solar LED street lights incorporate seismic detection

The argument for switching to solar-powered street lighting seems very clear cut: they run on sunlight, emit no CO2 emissions, provide an off-the grid source of lighting during in an emergency situation and use efficient LED-based light which tends not to attract insects. Sharp Corporation has announced plans to roll-out two new models of solar-powered LED street lights in the Japanese market and these have the added bonus of in-built Seismic Motion Sensors which detect earthquakes of five or greater on the Japanese seismic scale and respond by switching to full illumination for two nights.
