Apparently the landscapers when they were fixing the sprinkler system partially cut the wire going to my pool light. (This was from before I bought the house so I can't make the sprinkler people fix it). Currently it looks as though its running underground through a metal pipe. I can't pull the cable through to replace it so I am going to yank out the pipe and replace the wire. I was wondering if low voltage (12V) pool lights need to have their wires in some sort of conduit or can a wire just be buried like it is for my sprinkler system?
