The last working traffic lights in Liberia

At many busy road junctions in Monrovia, there are the remains of traffic lights. In fact there is a neighbourhood actually called "Red Light", named after the traffic light that used to be there. But there is only one set of working lights in the whole of Monrovia (probably the whole of Liberia), pictured, which is located outside the Freeport gates. I'm not sure if the Port Authority or neighbouring City Builders provide electricity and maitenance. But I hate these light! Traffic flows so much better without them! Olly
