I was driving down 7th ave and baseline when my wife saw a brightlights coming from south mountain it looked to be 5 or 600 yards west of the radio tower. We pulled over to watch it and we saw what looked to be a pattern of dimming. Than about 2min into it we saw on light to the left of the first light come in and begin to blink in and out then a third light would apear in the middle and do the same. I notice that they would go and out randomly in sync they never moved. so after 5 min of watching it we headed to the inlaws to get there camera when we came back one light was blinking as we began to take a shot it would disapear like ti new what we was trying to do. So i put the camera into record mode and it disapeared totaly. After sitting there for 5 min nothing came about. I was shocked and amazed cause once we go the camera it into record mode it just stopped.
