The city will begin installing LED traffic signals at 24 intersections in south Valencia between Interstate 5 and Railroad Avenue.

The city last week approved LED traffic signals for 24 intersections in south Valencia between I-5 and Railroad Avenue as part of a plan to swap out the city’s old traffic lights for the more efficient models.

When the work is done, 142 intersections across the city will be equipped with LED lights, along with new pedestrian signals, said City Traffic Engineer Andrew Yi.

LED lights consume about 90 percent less energy than traditional incandescent traffic lights, which saves the city money in energy costs, Yi said. They also are much brighter, more durable and last longer than incandescent bulbs, he said.

Incandescent lights burn out after about two years, said Signal Operations Supervisor Cesar Romo. LED lights last between 5 and 7 years, Yi said.

It will cost the city around $200,000 dollars to install and maintain the lights, but the energy savings will pay for the new lights within two years, Yi said.

In the next couple of years, the city will install 30 LED lights in north Valencia so that every intersection in the city will have upgraded lights, he said.

Santa Clarita began installing the lights in 2006 after the California Energy Commission passed a law requiring cities to use energy efficient traffic signals in 2004. LED lights have already been installed in Canyon Country, Newhall and Saugus, Yi said.  

Energy savings have already paid for lights in Canyon Country and Newhall, Yi said.
