Exposure to auto will always give a great still image - it will probably be crap at night even with that street light. Walk past it and see what it looks like and if you get blur. I would zoom in more, but that is personal preference how much you want to zoom.
WDR will cause artifacts at night and you should try every other setting first before using it.
