    Ya its lens flare, and the long exposure makes it a streak instead of a spot. Its movement of your hand over the 10 seconds.

    If you were to draw lines from each corner of the image to find the center of the photo you will see that the line in the sky is offset equally from the center in the opposite direction from the house light. This will be the case for both images.
    What you see is an internal reflection artifact from the lens. It’s always opposite the center point for bright lights.
