Plans to save money and cut light pollution by turning off street lights in quiet residential streets in Norwich are being discussed.
Norfolk County Council is consulting with the public on introducing 'part-time' lighting which would affect more than 7,000 street lights in the city.
The 13 county councillors who sit on the Norwich Area Committee are due to discuss the plans next week.
The proposal is to switch off lights between midnight and 0500 GMT.
A report to county councillors on the issue suggests the measure could achieve annual savings of £167,000 and says evidence from other areas shows part-time lighting does not result in increased crime.
