Re LED warning light for door. Just used a regular window or door magnetic contact switch. There are two types of switches ,normally open and normally closed. I think I used the open one. Mounted one part to the side of the door and the other part to the door track. I use 12 volt LED's and power them from an old charger from a drill or whatever . Just plug them into a receptacle and run low voltage wire to the LED. When mounting the contacts try and set them up with room for adjustment as they have to very close to each other in order for them to work.
