5 meter roll of waterproof led strip lights from Amazon. My thought was that I might use some of it for external lighting. These lights are 12 volt, some strip lights are other voltages.
inset a switch on the bottom of the cabinet, hidden behind the face frame. It's easy to reach if you know where it is located.
All this extra effort so I could add a light to the cabinets that holds our games and my personal "stuff" on the other side of the trailer.
