Small red lights that independently moved rather slowly.

At times these movements were quick bursts of speed followed by slowing down.  They at no time moved in a trajectory like an airplane.
They appeared just above the horizon looking east from Heath. Initially they would appear one at a time and then two at a time  They occasionally flickered pink or blue.  At the peak of the activity they appeared four at the same time and moved in a triangular formation upwards and to the right. 
These reddish lights were accompanied by orange flashes at times which would burst for a second at a time and appeared hologram like. 
These orange flashes were lower and closer to the horizon and did not move.
