Once a day, during nightfall the Berlin TV tower switches its warning lights from white to red. I love this, magic! and I’ve looked out for it often over the years. Tonight I finally caught this moment on video. Be my personal hero and watch the whole thing! Or skip to 1:00 min if you are in a rush ;))) … Or even better try to catch the moment in Berlin on the street, it is around 9:45pm currently.
