Open the blurry lights image and place it in the document. Set its Layer Style to Screen.
Apply a Layer Mask and mask out portions of the image that have lights under the crop of the image. Make sure all the lights that are left aren’t sliced.
In order to add a bit of contrast to the lights image, add a Black and White Gradient Map Adjustment Layer and make it a clipping mask for the lights image. Set its Layer Style to ‘Overlay’.
