12V problem-Now I'm really getting mad!

[Coolbreeze]

You saw my other post about the GFCI short now I turned on the 12V lights in the main room and they have a problem now also. Guess it is time for a thread on this problem. I have one switch for the 12 V in the rear near the frig and the other switch takes the 2 front lights. If I turn on the front lights the rear one glows, Same with switch over counter. Turn it on and the rear light glows and then same for the outside light. So the score is Gulfstream (-4) and me (0). 4 pretty crappy issues, de-lam ,the stupid water heater and now 2 electrical problems and not one fixed.

So the question of the night becomes can anybody tell me why the DC lights have 3 wires going to them? OK second question is how do you take these DC wall switchs apart. I would hope they are not glued but them must have some type of way to get them off the wall.
