Bright UFO hovering above Arizona

Here’s one interesting sighting of an bright object hovering in the sky above Bullhead City in Arizona. This happened on 30th October 2015.

Witness report: UFO observed for 30 minutes or More. Bright intense, changing lights, Changed into two objects than back to One. Witnessed for three nights in a row.
My father was walking to the grocery store right down the street. He noticed a long bright light up on the mountain ridge to the West. He came in and got me and his girlfriend and we went out in the front yard to watch this strange light. It was there for a good 30 minutes or more, and for three nights we saw this. The unidentified objects most mysterious thing was that it would be a small white light and then all of a sudden get brighter and brighter to where it was blinding and we could hardly look at it. It would move up and down a little but mostly kept its path going slowly back and forth in a North and South direction. It would blink, change color to red, Disappear then reappear. A few times it changed from one object into two than back as one again. I have many short video recordings on my camera. Every time I try to submit them it knocks me offline. This is my forth attempt at submitting this so I am just going to attach one video and one picture. You can let me know if you would like to see the rest. To see everything this UFO was doing you would have to watch all the videos. What is going on in Bullhead City ?? My father and I are very interested in finding out what that was we were watching for three days.
