It seems that your rear camera is generating significant halos around point source lights. I’m seeing this in my rear camera feed as well and thought it was because of the polarizer. I removed the polarizer and made sure the camera lens does not have any smudges or finger prints on it. I won’t be able to test again until tomorrow evening.
This is typical of night vision on dashcams. It's dark and the only source of light are the headlights. It causes overexposure and basically the halos occur. It happens on all dashcams I've owned. I bet tomorrow, you'll notice the same thing.
You can try a CPL filter to help with it, but there's really no cure all for this issue.
