Set of lights Alberta Canada Sept 3 2016

As i was driving north on Hwy 43 from Edmonton AB heading home to Dawson Creek BC i noticed a set of lights to the left of me (west). 3 yellowish lights with a 4th one flashing between the 2nd and 3rd light from the left. There was no sound and no movement from the object. I stopped on the side of the highway and observed it for at least 20 mins. Several pics and a video of it, including some pics with the background enhanced that shows the outline of the object. Was mayne 200 feet from the highway and approximatly 100 feet off tue ground.
