i dont know why i post so late.. i looked at it this morning.. and it makes sense now.. HAHA.hankster said:The cutout (I am guessing you are talking about this as the "indent") in the tube is where the wire of the plug fits into so the plug will go further into the tube and also holds the wire in that direction. So it is soldered in whatever direction you want so the wire is directed in the direction you want. Hope that is understandable.
