Two formations of lights.

My friends and I were outside smoking in the early morning.  We saw a bright light moving over a small mountain that sits next to my friend's house it was moving fast.  
It slowly turned over a field that was across a major road in town.  
Another set of three bright lights appeared slowly moving toward the other set of lights that went past the house.  They both flew around circling each other and then they left flying off becoming faint.
