18 glowing UFOs seen over Phoenix AZ tonight, 10/12/12 8:45PM

I was driving down Greeenway Road in Phoenix heading west approaching 19th Avenue when I and my passenger saw what appeared initially as a large strand of lights in the sky. No such lights have ever been present in this neighborhood as I work in a business only six blocks from where I saw these lights.  The lights from a distant seemed stranded together but upon arriving for a view under each light each object was separate from the others. Each shape (kind of oval) was uniformed throughout.  Each had a different altitude(some higher some lower)from one another. And each craft had two oscilating, dull lights on the their underside.  To be honest, they looked like candles flickering and masked inside a pumpkin except that there were no openings but rather light that was diffused as being filtered/masked as if inside a lamp shade or parachute material.  Never have seen such a spectacle in the sky like this.  Thought I heard a jet engine but the traffic was heavy and! I couldn't be certain given the roar of the street traffic. Were residents spoofed for a Halloween trick here in Phoenix?  
I haven't found any information on this loose formation of lights that flew through Phoenix tonight.  The event was just bizzar.
