Some street lights would be turned off overnight
Some Leicestershire street lights could be turned off and others dimmed to save money, under county council proposals.
Council leaders have estimated £700,000 of taxpayers' money could be saved annually by pulling the plug on the lights.
The council spends £3m a year on providing street lighting.
The move would also cut carbon emissions from power stations by 3,000 tonnes a year, according to calculations by the authority.
The plans are to turn off up to 40,000 road lights between midnight and 5:30am starting with lights in Quorn, Thurlaston, Dunton Bassett, Swannington, Smeeton Westerby and Lubenham.
It has proposed dimming about 2,000 roadside lights on main routes between 2200 and 0700 and switching off about 1,000 lights in rural areas where they are not near homes.
The county council said it had consulted the emergency services and so far they had not raised any objections to the idea in principle.
It said it has looked at similar attempts to slash power bills and emissions in other parts of the country including Gloucestershire and Essex.
It said that, despite street lights in some areas being cut back, there had not been any significant increase in crime.
The county's cabinet meets next Tuesday to discuss this plan, but there is no firm date for the scheme to start.
