I have flood lights at all four corners of my house that are controlled via a single switch in my bedroom. When the dogs start acting weird I hit the switch and look out to see what's up. This is nice but the problem is that they only illuminate a limited distance. I would like to install a few more lights at strategic locations around the property, my gate for example. I rented a ditch witch and I've run power out to these locations but I'm not sure the best way to turn the lights on and off. I would prefer NOT to have them on unless I want them on. Any ideas? Wireless of some sort maybe?
