In December Ealing Council installed seven solar-powered LED cycle path lights along Ridding Lane in Greenford. The lights are already used elsewhere in Europe, particularly the Netherlands, where some towns use them to mark the edge of cycle paths. According to Falco, the manufacturer, they are programmed to come on at night, can run through a three month long Nordic winter, and can be powered for up to 10 years on a single rechargeable battery. They can withstand a load of 20 tonnes and are resistant to roadsweepers and gritting lorries. It's not known if Ealing have installed the version that flashes when the temperature drops below 2 Celsius to warn of icy roads.
