Strange light caught since a road in Yellowknife, Canada

On December 3, 2017, several witnesses were driving on a road in Yellowknife, in the Northwest Territories, Canada, when they saw some strange light in the night sky.

Witness statement:

My auntie was driving when I looked out my window a bunch of white lights in the sky appear. We thought it was a airplane or helicopter. But then the lightes disappeared and one beamed back in the sky so we pulled over and took pictures. But then a hovering thing started changing colours. I felt scared and curious but my auntie started driving and I lost sight of the UFO.
