I have shot a little video of the drawer light in action.
Also, I have a single picture of the device installed on the shelf, behind where the drawer will go. As can be seen in the video, the drawer itself is made from fabric, which is one of the main reasons the solution is made the way it is. A hard drawer (with a back plate as end stop) would only require a simple mechanical switch. With this drawer I am not completely sure where the back side will end up.
