Zebra crossing lights

Streetworks are a necessary part of maintaining the urban landscape - lights need to be replaced, cables need to be laid and roads need to be resurfaced. Unfortunately in London, it seems that some work will begin, complete with bright orange plastic barriers, then nothing will happen for several weeks. This is a particularly annoying thing for me - it looks ugly and is down to terrible planning and sheduling by the authorities. For some time in Angel there have been two identical zebra crossing lights side by side, the one being replaced still works perfectly but it did not stop the council digging a hole alongside and placing another one. It has been like this for about 8 weeks. So I made a sign to highlight their incompetence.
