Red blinking light, movimg in fluid motions, accompanied by zero sound.

Witnessed a blinking red light.  At first I thought it was a plane.  However the object was accompanied by zero sound.  
The light appeared to move on fluid and zig zagging motions.  Often the light would stop and hover before moving.  At times the frequency of blinking became much more rapid.  The light was also accompanied by a white blinking light that appeared to be attached to the red light.  
Object lingered for about seven minutes before moving slowly away to the east out of sight.
 Weather:  partly to mostly cloudy.  Light wind.  Some visible moonlight from full moon.
