Please allow me to scythe through my perception of ambiguity in the above post. What I meant to delineate is the three lights in the brief clip
formed a triangle if you drew a line between each to the other.

Point taken, unfortunately, they still look like a row of emergency vehicles, and if you can provide evidence to the contrary I'm sure the posters here will welcome the additional info.

On about the 14th of Octobber I was traveling west on Hwy 60 outside of Mesa Arizona when I noticed a series of lights forming a triangle southwest of me. I pulled off of the road and grabbed my 10x50 binoculars out of my backpack and looked closer. What I saw apalled me. I noticed six FLARES arranged to form a triangle. I could tell they were flares because of the tell tale plume of smoke that they give off. There were six identical plumes. I cannot tell if the objects being discussed are the same ones I saw. I saw the original Phoenix lights and they were not flares.
