Formation over Welton, AZ

Welton, AZ

While merging back on the westbound I-8 from the Ligurta Truck Parking area, just west of Welton, AZ, between 9:30 and 10:00pm, Thursday, 6/8/17, I noticed a V-shaped cluster of yellow lights in the southern sky toward Mexico. After a few seconds, they disappeared all at once with a slight decay. It looked like someone had turned off distant, but powerful, lights, and it took a second for the filament to fully dim. Could also have been them disappearing behind distant clouds. It was confusing and I thought maybe I had witnessed some sort of reflection onto my drivers side car window that went away as I drove. I continuously looked into the southern sky, but never saw it again. About 20 minutes later, between Yuma, AZ and El Centro, CA, I noticed a pilot in a small propeller aircraft doing aggressive maneuvers in the night sky, intermittently turning on and off 2 lights on the ends of each wing of his plane. Perhaps he was doing night time crop dusting. I also later heard there was fire in the area so could have been dropping flame retardant as well. As this is an agricultural area, I assumed I has seen lights on the wings of crop dusting plane or planes. But now not so sure after reading the other reports from further north at the same time.
