Night time sigting of two objects hovering then streaking over horizon.

Me and friend were traveling west on Ninevah Rd. and after arriving at the east point of "three corners" (Which is a hill, we come up over a hill) we noticed two objects not shining but like "glow in the dark" objects that were stationary (their positions were not side by side but the left hand object was slightly higher than the right) and upon cresting the small ridge they took off one right after the other at a unbelievable rate of speed till they vanished over the horizon to the south toward Lawrenceburg.  My friend (which I dont want to involve but he is alive and I dont have permission yet) both of us were very excited of course and pulled off the road to "let it sink in" so to speak of what we had seen. 
The whole thing maybe lasted 5 seconds and it is not much to go on but we did see something and dont have a clue to what it was... sky was clear, it was night time it was warm weather windows were down, it was not a reflection off dash board lights on th! e windows, I was in the passenger side and "friend" was driving.
Witness indicates that date of the sighting is approximate.  PD
