Milton Keynes Council will be introducing cutting edge lighting technology in the city's underpasses.
The council is undertaking an energy saving conversion of all underpass lighting across the city, using the latest LED (light emitting diode) technology.
The aim is to complete all of the conversions by the end of the year, installing 3,400 LED lights which will save an estimated £93,000 per year through energy costs.
LED lighting is designed to operate for around ten years, with a minimal need for maintenance, unlike conventional fluorescent lamps that require more frequent replacement.
The switch to LED lighting will significantly improve the underpasses making them brighter and more visible and therefore safer.
As an additional cost saving exercise the council will look at turning off the lights when not required during the hours of daylight to further save costs.
Cllr John Bint, portfolio holder for highways and transportation, said: "The new LED lights will provide a cleaner, greener source of lighting for people using our underpasses.
"We hope that these improvements also go a long way towards making people feel safer when using the underpasses and will encourage greater usage of our redway network which is currently under used by cyclists and pedestrians alike."
