After @YukonJohnCan's post, drawing attention to the chapter markings, I took another look at the video, this time skipping through it to view any chapter named "ORB". As I thought, what is being reported as orbs, are the small dots and occasionally, short streaks of light.

Looking at the area driven through, on Google Earth, it's seems clear that there are very few buildings in the area, so I think that the bulk of the lights seen are not going to be from building lighting. However, there are a few buildings out there and given that it's dark and apparently pretty clear weather conditions (given that the lights appear to be pretty distant from the camera) then lights on buildings could be seen from many miles away. That being said, the most likely source of these points and streaks of light, is probably other vehicles on the road ahead.

These could be travelling in either direction, with the headlights of those travelling towards the camera, being seen directly, and those of vehicles heading away (so driving in the same direction as the camera car), seen reflected by the snow at the side of the road.

The appearance and disappearance of the lights, could be due to either the car with the camera in it, or the other vehicles on the road, moving up and down with the undulation of the terrain, so intermitently dropping in/out of sight of the camera, or making their way around bends. There doesn't need to be many vehicles on the road either, (i.e. there don't need to be one per lights identified as "ORB" in the video) as each vehicle on the road could potentially be seen multiple times, even appearing at times on opposite sides of the road, due to route the road weaves through the terrain ahead of the camera.

@YukonJohnCan is there a compelling reason, something that I'm not seeing, why these lights can't be those of other vehicles on the same road, seen a few miles ahead?
