Extremely annoying night light problem

Hi everyone,
I've got a problem that's really bugging me at the moment. Recently I had this really weird feeling that I'd just like to reinstall FS - i.e. delete all of my addons and the whole game too. So I installed it again and now I've got this weird problem when flying at night. I can't remember if I had this problem before the reinstallation.
I've uploaded some pics so that it can be seen clearly. Whichever "block" of scenery I'm in is in a blackout, and as I fly out of it, it lights up gradually until I'm in another block which in turn then blacks out and so on...
Any ideas?
