The figure was revealed as Councillor Campbell made a number of enquiries about broken street lights in Creggan.
Councillor Campbell said
A number of residents from Iniscarn Road in Creggan have complained that there is a number of street lights out and the street is very dark.
I have spoken to Transport NI and reported them. However, there is a back log of over 400 lights out in the city and this is causing a major problem.
During my discussions with Transport NI I emphasised the point that Iniscarn Road has a large pensioner population and this is causing difficulty for them.
I will continue to lobby Transport NI to have them fixed as soon as possible.
If any resident has any queries or issues to discuss please do not hesitate contacting me on 02871 377551.
