Quadrille in the Dark

This video is pretty amazing. It is taken at the Royal Horse Show in 2008 with four horses being ridden in the dark with LED lights on their bodies. I have seen other riders that have done something similar but I think this is the original group that came up with the idea. I wonder how much you can see while you are riding and if it is hard to get the horses used to it. The lights may give off just enough light that you feel pretty confident knowing where all the other riders are. But the walls are not lit up so they must have to pay close attention to their music! httpv://www.youtube.com/watch?v=oiiiwlnGW1I
