Amber colored spheres following the vehicle, moving in erratic directions in the Maccan area

One night as my sister, my mother, my grandmother, and I were travelling from Parrsboro to Amherst, where route 302 and 242 connect, I happened to look out the driver side of the vehicle.  As I did, I noticed 2 golden sphere shapes in the window.  At first I thought they were a reflection of the amber colored street lamps in that area.  Then I realized that they were actually outside the window, approx. 30 - 40 feet from the vehicle.  They were moving erratically, around each other almost following the car, staying about the same distance away.  I told my family to look, and they also noticed them.  I wasn't scared, however was a bit anxious, not sure why.  They followed the vehicle on the waterside (driver side) for approximately 10 minutes before they just disappeared.
Time and date are approximate.  PD
