4 lights moving quickly into a line, then disappearing one at a time

4 bright white lights in sky  Seemed to be over Black Mountain, Rancho Penasquitos  One light zoomed into place, then stayed still, a second light zoomed across it then stayed still, right beside the first.  A third light did the same, and then a fourth.  After they were all lined up in a row, the lights quickly went out, one after another, starting with the first.
They didn’t seem to come from anywhere.  We didn’t see them flying from a distance to land in this space.  It was like they appeared, moved into place, and then disappeared just as quickly.
Two moms taking our two teenage daughters to a concert.  Both moms and one daughter saw the lights.
