I was looking to see if I can get some advice from you electrical experts. I am wanting to redo my lighting wiring in my garage. My objective is as follows (I will attach some pics so people can see what I am talking about). I have two light switches in my garage, one controls the lights inside the garage (the switch on the right), and the second switch controls the outside lights - the light in front of the garage as well as the back of the garage. What I would like to do is to add another light switch so I can control the outside lights separate in front and in the back of the garage. Right now the left switch turns on the front AND back lights, but I would like to add a motion sensor light to the outside light facing the house, so this would entail me having to keep the light on the "ON" position for it to work at all times. So my problem right now is that I cannot do that without having my back lights on constantly. So if there was an easy way to just add another switch in so I can control the front or back lights separately, that would seem like the easiest thing to do. Any advice on how I would do this would be much appreciated, thanks in advance.
