Three white lights in the shape of a triangle flying low and slow. Alternating lights of green and red. Blue light strip along side.

December 6 2022. Summerwood neighborhood in sherwood park.
It is winter here so pitch black outside still.
At 6:41 am I was driving to work and I saw three bright white lights in a horizontal line just above the two story houses in front of me as I was driving southbound. The lights appeared stationary from my view. I drove to get a better view from an open field around the corner ( 30 second drive). I was now east of the object. I saw the three white lights were in the shape of a triangle. The bottom left light also had a smaller flashing green light. My car was on, but I could hear no sound from the object. It flew low and slow. It flew directly over my car, so I looked at it through my sunroof, and I could see there was a line of blue green colored light that went along the left edge of the triangular shape. The object moved slowly and at a consistent speed over me and to the north. I drove out of my neighborhood to highway 21 and I could see it in the distance still, but now it was flashing red where it had been flashing green, all three white lights still bright.  As I drove north down the highway I could see the object started alternating the white lights on and off, sometimes the right light was on and others off, sometimes the left and others off, in a random order. The object eventually was too far for me to see.
There is a military base north west of where I live, and so this could be military technology.
