Was Planning Permission Granted for this Illuminated Advertisement in The Ferry?

A constituent has queried with me how it was that display advertisements on a bus shelter in Brook Street were now illuminated 24 hours a day? These illuminated advertisements seem to have replaced non illuminated ones which are a common feature of bus shelters in the city including The Ferry. 

The constituent thought that the illuminated advertisements were much more visually intrusive; which to the advertiser I suppose is the point of them?

I have written to the planning department for clarification.
