I am installing two wall sconces in my primary bedroom on either side of the bed. The staright up install isn't an issue but then again, I can never just install something normally. My goal is to have a switch on each side of the bed that can turn on both lights, turn off the light on the switch side or turn off both lights. I am wondering if there is a single switch that works this way. I can do a standard 3 way switch but then they are both either on or off. I want them to also be able to be on independently. Any ideas?
