Pedestrian lights are very common, and you'll find quite a few cycle lights around. But have you even come across lights specifically for horses to cross the road?


The control panel, situated high up (at horse - or rather rider - level) carefully explains that red means "stop" and green means "go". interestingly, red and green aren't the ideal choice of colours due to around 8% of the male population being red-green colour blind, and indeed WHITE was the 'stop' colour in the very early days of the railways. "Not such a big problem as you might have thought -the countryside was very dark in those days" said a book I read many years ago. Does anyone know what proportions of horses are colour blind?
