OK, so Traffic lights are mostly used in urban area, what happens when the panel is in the shade at certain times of day? This can cause a reduction in efficiency of up to 90% so then you are back to using you grid source. When you add it all up this product would probably have a buy back period of over 20 years and more energy would be used to have it in place rather than leave the traffic lights alone. Along with the colour issues others have identified I cannot see any commercial merit in the prouduct.
