Amber lights in southern night sky near Gila Bend, AZWhile drviving eastbound on Interstate 8 between Dateland and Gila Bend, I noticed a cluster of amber lights directly south of the highway. At first I thought nothing of it thinking they were lights on top of a tower or something. After approximately 15 seconds of driving at approximately 85 miles per hour I noticed that we were not gaining on nor passing the lights. That's when I brought them to my wife's attention. For almost 3 minutes at 85mph the lights never changed position in my view out the passenger side window. I pulled to the side of the highway to look at them and they appeared to be motionless. The only thing I noticed is that there may have been a small smoke trail rising up from the center of them. Then abruptly, they all went out.After a short conversation about how freaked out we were with what we had just seen, the lights reappeared again. Only this time there were 2 pairs of lights with one pair slightly rearward from when I had seen them and the other pair were in my view between my inside rearview mirror and the side pillar just under the passenger visor. Without knowing how far away and high up they were, it is difficult to say how far apart they were. But as before, my view of them never changed position no matter how fast I drove. Then 1 pair went away then about 30 seconds later the other pair left. ((NUFORC Note: Possible military flares at Gila Bend firing range?? PD))
