It was originally installed in 1998 at the Westferry roundabout near Canary wharf, a large financial district in London's docklands. It was removed in 2011 so that work could be carried out to reconfigure the traffic flow. As a consequence it could not be returned to its original setting but after a couple of years in storage it has found a new home on the Trafalgar Way roundabout near Billingsgate fish market. As you can see work is still going on to its setting but it is good to see the lights on again.
When it was first erected, motorists were confused by the numerous light changes but it soon became a favourite amongst the locals and visitors to the area.
