Well they do come on. However, they only light (some) surfaces. If I pan with the mouse slightly, they light the other surrounding surfaces that they are supposed to. This includes the player himself. Please see the photos. You will notice the player in the same position in both pics. In the first pic (unlit surfaces), The light is actually on but is only lighting some of the surfaces within it's light range. In the second pic(lit surfaces), the view has been rotated very slightly, thus lighting the other surfaces. this is the same with all lights in the level.

Thank you much
