Special compact bases on the Traffic Lights keep them upright even on the windiest of days. Safe and sturdy fittings abound ensuring these signs will last and last and last. The effect of the lights on the Traffic Lights is created by using coloured balls painted black on one side. As they are rotated, using special turning rods, the balls give the effect of the lights changing. This product has proved to be a instant hit with the Road Safety Officers. The 'wait' panel clicks as it is rotated and the 'flashing green man' can change back to green and red. H.1100mm. ALSO AVAILABLE: In sets or individually PRICE: Price shown is for one unit only.
