You don't need to rewire your house in order to install motion-activated lighting. The Motion Sensor Lamp Control Sockets are triggered by a weather-resistant motion sensor that runs on two AA batteries (sold separately), so you can set up this system in minutes. When the motion sensor is activated, it sends an RF signal to both lamp sockets, which will turn on lights in your home, so you'll know instantly if a prowler is on your property or if guests have arrived.
