You are my sun sign

The first solar powered road sign in Devon, UK, was installed at a busy junction on the A38 near Watts Cottage, Burlescombe, Tiverton in 2004. The Solagen SAS 600 sign warns drivers, as they pass, to slow down for the junction. Speed readings taken before and after the warning sign was installed showed a general reduction in speed of 6mph and a reduction in the number of drivers approaching the junction too fast. The Solagen sign has no energy costs and low maintenance requirements. With an expected life span of 100,000 hours, the light emitting diodes (LED) should be in operation for 27 years. Installation costs were #5,000. The sign is fitted with a photo-sensor that adjusts the LED's output according to ambient light levels. The radar detects vehicles up to 100m away, allowing a warning to be given.
