It’s trees cracking

Yeah, two out of the three times I saw the lights I described I was with someone else who saw them too, or spoke with someone else who was in the area that saw them at the same time. Two of the three times I was outside (not in my car) and there were no sounds. Weird.

Were they just flashes? I saw orange flashes/lights zig zag across the night sky a few times when I lived in the Thetford area years ago. I have no idea what they were though - unidentified aerial phenomenon :)
