The 2nd shot is from a lower angle, so if the lights were on the wall, they wouldn't be visible in the 2nd shot.
Perhaps your half-correct Harmy. But I reckon we should have seen the uppermost light in the follow-up angle, as it happens to be almost as high as all the yellow lights dotted along the very top of the railing. Let's see what adywan thinks anyway.
