Multiple lights appear around on the mountain.

Looking south from Phoenix to the south mountain. No one really hikes there at night . Rarely see if anyone do. Never seen any vehicle go up there let alone multiple lights I saw this last month but I was able to film this time. One light appears and then there’s second light at least 30 seconds and then multiple lights at least 10 to my count appears. All in line, multiple lights moving to the second light is real bright. It appears that many lights went in to or pass the bright light then the middle lights appear even brighter. Multiple lights seems go in or pass the bright light in the middle. All disappeared right after that.
