Multiple lights hovering in a row North of Phoenix!

On Jan. 28th, 2016 at approx. 7:30 P.M..
I was traveling northbound on Hwy 87, just past Fort McDowell Casino and I spotted 4 lights in a row, as I was looking northwest.  These lights were bright white in front and flashing red lights from side to rear.  After I passed and looked back they were no longer visible, however there were several more ahead of me.
While driving, I noticed several vehicles pulled over and people standing on the side of the road staring at the objects which drew my curiosity to watch these lights closer.
At first, I assumed they were planes but as I got closer I noticed that the lights seem to break off and stretched for miles of approx. 12-15 bright lights in a straight line. Roughly 200 ft. west of Hwy 87 and approx. 500 feet above ground.
I didn’t become suspicious until about the 6th light that I passed, I then pulled over about a mile before Bush Hwy exit and got out of vehicle, it was very quiet, no sound and objects remained very still, hovering.  I tried to capture a picture but it only looked like a bright dot (crappy cell phone camera).
After approx. 5 minutes of watching these objects remain motionless, thoughts began to run through my head, as I was trying to rationalize what these were, drones, planes, or military crafts etc. My only logical conclusion was UFO’s which prompted me to get back into the vehicle and drive away, heading northbound on highway 87.
While driving past the Sugar-loaf/4 Peaks turn off, I spotted several other lights hovering east and west of the highway.  There was 2 remaining lights in front of me.  After I passed the second light, I didn’t see any more and that concludes my sighting.
