Add Christmas lights to building

For this photo I would need somebody who could "switch the lights on the left side of the building (vertical light chains) on" During the shoot they were unfortunately off due to a short circuit. It should look as natural as possible - for reference on the right there are light chains that worked properly :) If you have any questions please feel free to ask!
If that image turns out nicely I potentially have a few more with the same issue :)
