UFO Sighting in Gardner, Colorado on 2018-03-02 22:09:00 - Bright lights in the sky lit up ground- looked like 4 headlighs in the sky moved miles in a second reappeared in totally different area

Sitting on a friend’s front steps at about 10pm talking when a bright light caught our attention- like headlights coming up over a hill but they were far above the horizon. they were bright enough to light up where we were standing like a searchlight then they faded out slowly 1 at a time. a second or 2 later they reappeared 1 at a time in the same sequence but miles away to the left and further away from us, this happened 2 more times then about 1 minute later it happened again but to the right of us and much further away. each time was accompanied by a very loud, low rumble that would stop abruptly as the last light went out. when we tried to capture it on film the lights went out and we never saw it again.
