Several red fireball lights, fading in and out of view on the horizon, with occasional white explosive lights.

Location of where we were standing: (34.6078352, -113.5292099) BLM land on Signal Road just south of HWY 93, southeast of Wikiup, AZ. We were looking in the direction of Wikiup (to the northwest). At 8:15pm my fiancé said “Hey, do you see these lights in the sky? Come here!” I looked to the northwest and saw several red lights dimming and increasing in intensity on the horizon and also disappearing and reappearing. At most we saw 13 red lights at the same time in various formations, but most often it was between one and four red lights at a time. We watched the horizon for over half an hour. On three or four different occasions there was a big white explosive burst of light in the sky next to a red light. This white light expanded to a bigger circumference than the red lights, and also faded as if it were a cloud of smoke dissipating.
Around 8:35pm we saw two red lights zoom away from each other rapidly and then fade to darkness a second later. This was the first time we noticed they could move, which was really exciting. All the other times, the lights faded in and out in stillness, but this time it was clear that they were floating in the air and could propel themselves to move very quickly.
The clouds above the lights sometimes reflected the red color of the lights and also the white explosive lights- it looked almost like lightning, the way the clouds lit up on occasion during this whole ordeal- but the weather was not lightning storm weather at all, so this was peculiar.
