When did we start using LED traffic lights?

    LED traffic light lamps were developed in the mid-1990s. Prior to this date traffic lights were designed using incandescent or halogen light bulbs. LED lights are much more efficient and can be solar-powered. It is far less expensive to use LED lights, and s a result, most new traffic light deployments in the United States, Canada and elsewhere have been implemented using LED-based lamps. Many existing deployments of incandescent traffic lights are being replaced.
