Diversity traffic signals at Trafalgar Square

The pedestrian crossing signals in London’s Trafalgar Square are fitted with a variety of different green lights, such as can be seen in the two examples in the photograph. I have not seen these sorts of green signals anywhere else in London. They are a part of a project to promote ‘diversity’ in London.
