Traffic lights warn of tides on deserted Sully Island

An island which has no roads or residents is being equipped with traffic lights - after visitors kept getting cut off by the tide.

Sully Island on the Vale of Glamorgan coast can be reached by foot at low tide via a rocky causeway.

But over the years hundreds of people have been left stranded on the island when the tide comes in.

So the RNLI is trialling a set of traffic lights to warn visitors when they are likely to be cut off.

Regular visitors say it can be a dangerous area.
