Bright mystery lights were filmed by a family driving at night in Arizona. The lights disappeared and reappeared, and at times appeared to move. Check out the video and testimony submitted to MUFON (case 81684) and picked up by a YouTuber:
My daughter and I were driving at night in the dark when we noticed 4 lights that looked very bright above the distant mountains. Four of them lined up next to one another from right to left. They stayed stationary for a few moments and then 1 would fly swiftly away from the others leaving 3 in a linear horizontal line before it disappeared. It would spontaneously reappear and then fly above the other 3, move left again and then realign with the other 4 leaving 4 brightly shining in the sky. We also saw a distant airplane but it appeared farther away, higher and with blinking lights. The UFOS we saw were solid bright white/yellow and were brilliant against the night sky. They flew fluidly, and would move great lengths across the sky in an instant, disappearing and reappearing. They were much larger than stars in the sky and brighter than the brightest star. We felt excited and in awe, and happy they would reappear so we could get good pictures and videos. Our neighbors also saw them while out driving. We finally left to go home. We have seen them before in a dark night sky over the Estrella mountains to the East. They are common in this part of Goodyear. We see them several times a year.
