Beings and a landed craft.

I had an experience a couple of years back.
I was on my way home, I was driving a bit too fast and then it flashed really bright, I believed I drove threw one of those automated speed cameras.
Well guess again, I didn’t and I realized that when I turned my head to the left and the light became constant, it was coming from the woods next to the road, there was a tree line close to the road a little hill up and a house on the top.
The light was coming from below the house almost at the top of the hill, ca 150 meters away from the car and was directed strait into my car, when I say bright light I mean it was so white and so bright it reminded me of a blitz but it wasn’t because it was now constant light.
My window wasn’t all the way up and when the light was turned off I saw several white shadows in the forest right next to the road running after my car, believe me when I say it was running really fast, I could hear a lot of cracking sounds as the debris from trees where stepped on, and the sound of something running through high grass.
I never turned my head to side window again, it was like something told me not to look, I just kept looking straight forward and kept going, I didn’t think to much about it then, but I was wondering about the light, Never before had I seen a light that bright.
A couple of km up the road I noticed a triangular arrangement of lights, red, green, blue, it was on the ground close to the mountain wall, it had 1 light above and 2 on bottom, the sides were not strait it was slightly rounded.
At first I believed it’s probably just an entrance to a military facility or something.
It was really dark and there were no lights except those 3 colored lights, they didn’t light up the surroundings and I could barely see a shape between the lights.
Thinking about it later I asked myself these questions: Would the military put an unguarded entry (no fence or anything) right next to the main road? Have u ever heard of a door being marked with red, green, blue lights? Why didn’t I notice it when I was driving the other way?  I think the blue light was on top and the red and green was on the bottom, this is 2 years ago so I don’t exactly remember how the order of the colors was.
I was on my way from Notodden in Norway to Porsgrun.
Could it be that this was some beings not humans that chased me, and those lights where coming from  landed craft?   
I’m hoping this site allows comments because I would really like to figure out what this was.
