How do I get a light to attach to the face of a cabinet. Specifically I created tall bookcases and want to place a light on a wide stile. I got it to attach on one spot but cannot get it to attach on another. Any tips? You can see one snaps to the wall and I cannot get it to pull forward. I tried coping and reflecting the one that is on the face but it still snaps to the wall. Help.
