Nearly 100 traffic lights in Somerset, a third of the county’s stock, could cause a risk to public safety, the county council has said.
It is now investing £250,000 to repair and replace them, after accepting the safety of the public could be affected.
The average age of the stock of traffic signals – and the county’s 54,000 street lights – is increasing.
Councillor Harvey Siggs said currently all lights are safe despite being “beyond their design life”. The design life for both traffic lights and lighting columns is normally around 30 years.
