LED Traffic Lights Take Hold in Kentucky
Transportation authorities across Kentucky have been replacing the incandescent halogen bulbs in stop lights with energy saving Light Emitting Diode (LED) bulbs. In addition to saving energy, the LED bulbs require less maintenance. LED technology has been around for decades; however, only recently have LED prices fallen to such a level where it became cost effective to them in traffic lights.
