"New York City is transitioning its 250,000 street lights to energy-efficient LEDs in an upgrade that should be completed by 2017. CBS reports that Mayor Michael Bloomberg announced the time frame today, noting that the upgraded lights will save city taxpayers around $14 million a year once the transition is complete.
