Two white lights one vertical to the other approx 70 degrees from horizon

Two lights were flying in tandem as I was driving. I thought it was the Phila to Harrisburg regular evening flight but the lights’ arrangement was odd. As I turned into grocery store parking lot, the movement stopped. The lights remained in place as it looked to be over a military area north west of lebanon called Gap. I watched for 5 minutes from dark area of parking lot and took a photo which showed a single circular light, not the two that I saw with naked eye. I returned to route 322 to drive a mile east to a 2nd store and the lights moved parallel to my driving, very fast, but then returned to prior area within a few minutes. When I exited the store I returned to the original parking area to find that they were in a similar location but not exact as I had seen them half hour earlier.
I then returned home and stopped watching. Lights were white and object itself couldn’t be seen. When it was the closest initially I didn’t look since I thought it was a plane.
