New Traffic Lights For Kentucky

Louisville, KY – Kentucky could soon become just the second state in the country to convert all of its traffic signals to energy-efficient, light-emitting diodes.
The Kentucky Transportation Cabinet announced a contract with Siemens Building Technologies to swpa out incandescent lights with LED's at more than 2,500 intersections state-wide.
Cabinet spokesman Michael Goins says three color traffic signals at the intersections should be upgraded within six months.
So far, only Delaware has completed a statewide conversion.
LED signals are 80% to 90% more efficient than incandescent lights and they can last for more than a decade. Incandescent bulbs usually burn out in less than a year.
Across the state crews have installed LED signals at about 600 intersections, many of which went up last year
