Traffic lights

I was driving everyone home in the dark tonight after a fundraising meeting for Transfabulous when we approached these traffic lights at a roundabout in the concrete jungle that is Docklands.

I stopped the car and asked my passengers, Serge, Jason and Jamie: 'What the f*ck is that?' Two of them knew it was a sculpture. Apparently it's famous. As a new driver, I can only say it is the most frightening thing I have come across for some time, which is saying something in London. I had no idea which was my light.
