LEDs in LA's traffic lights expected to save millions

The city of Los Angeles has just finished a five-year project to retrofit its entire network of traffic signals. Bonus: It’s expected to save taxpayers millions of dollars.

City crews have been busy converting all the city’s traffic lights and pedestrian signals from incandescent bulbs to LEDs. L.A. Mayor Antonio Villaraigosa said the LEDs are about 85 percent more efficient than traditional lights, adding the conversion would save the city about $4 million a year. That project is being financed by a $40 million loan by the Department of Water and Power. Once the loan is paid back, city officials expect that the new lights will save about $10 million a year.

The city is also working on converting two-thirds of its 210,000 street lights to LEDs.

The mayor also announced the completion of a traffic light synchronization program in San Pedro. The project, which monitors traffic conditions and changes signals in real-time, links 64 intersections and adds 17 new left turn arrows in the harbor area.
