The City of Syracuse, New York, has improved traffic signals at 299 intersections with energy-efficient light emitting diode (LED) traffic lights. The new LED lamps, installed in 10,044 traffic lights, will help protect vehicular and pedestrian traffic and save the city more than $225,000 annually. The city partnered with the New York State Energy Research and Development Authority (NYSERDA), which contributed $537,240 to the project.

Incandescent lamps in traffic signals were replaced with LED lights, which have 10 times the life expectancy of the incandescent fixtures. Energy savings are also considerable because a red incandescent lamp requires 135 watts and a 12-inch red LED uses just 10 watts. In an LED fixture each colored light consists of more than 100 light emitting diodes. For example, if a red incandescent lamp fixture burns out on a traffic signal, the entire red light is nonfunctional and part of the intersection is without that particular traffic signal. With an LED fixture, if one LED that composes the red light burns out, the remainder continue to function and traffic flow through the intersection is not interrupted.

"In efforts to reduce electricity consumption, save money on utility bills, and protect our pedestrians and motorists, we invested in the new, improved traffic lamps," said Mayor Matthew J. Driscoll. "The new lamps significantly decrease maintenance costs and improve motorist visibility. The city expects to see a payback of our investment in less than 2.5 years, and we thank NYSERDA for assisting us in financing this project."
