My son and I witnessed 6 round yellow/orange blinking lights traveling very slowly in a line south of Glendale, AZ, moving from west to the east. While watching, a tiny little light appeared and then vanished under the first light. Unfortunately, my son went to get his camera and as soon as he came back out each light blinked out one by one, starting with the first one. My son was sitting on the balcony of our apartment when he saw the lights. We live in a third floor apartment. He called me to come out to see them. They were between two trees and there were never any lights there before so we kept watching to see what would happen. They kept moving very slowly in a line until one by one they blinked out.
