Bright white light weaving back and forth in the sky above us.

My boyfriend and I were sitting in my car in my driveway talking after we came home late one night, around 1:30am. We noticed a light that was bobbing and weaving all around as it came up over the eastern tree line back past my pond, about 200 yards from where we were parked. It proceeded to fly over to where we were parked at and hover in the air almost directly above us, I would have to guess and say it was maybe 100 feet in the air but close enough for us to use binoculars to see the triangle shaped bright white light with 2 red lights, one on each side of the top point. It's probably 4 or 5 feet at its widest point. We could hear a loud buzzing sound the entire time it was present. A few times it shined a beam of light down like it was looking for something. We watched this strange light for hours. I downloaded a sky map and it wasnt showing up on it. We also noticed lots of birds were chirping loudly the whole time it was there too. We continued to watch it until daylight when it started to get higher in the sky until it disappeared. It has came back every night since and we watch it every night. It comes up over the back treeline by my pond and will come so close to us and hover there moving back and forth in the air all night until daybreak then it leaves. We have pictures and videos but not very good quality because they were taken on a phone sitting inside my car.
