Plans to switch off some street lights in North Somerset at midnight have been suggested in an attempt to cut the county's £500,000 electricity bill.
Councillor John Crockford-Hawley believes switching certain lights out in areas which were illuminated "far too much" will help reduce costs.
"There would be a crime and accident audit first," he said. "The last thing we want to do is make an area unsafe."
A similar scheme was piloted in Essex earlier this year.
Essex County Council gave a "clear undertaking" it would consult with police on a case-by-case basis as to whether switching off lights would have an impact on crime and disorder or on road policing and road safety.
