Never walk into a dark house again. Turn on ‚¬â€œ or turn off ‚¬â€œ lights and small appliances from inside the car with your remote and the Chamberlain ® Remote Light Control. It plugs into any wall outlet and automatically ''learns'' the code(s) your garage door opener remote control transmits. Then you simply push the correct button on your remote, and the lights will turn on or off.
