Adding safety measures to your home doesn't have to involve expensive installations and a hefty increase in your electric bill. Keep your home safe using the sun's free solar energy by setting up the Solar-Powered Motion Sensor Outdoor Light . This motion-sensing light is triggered when you enter its 23-foot range, so it can light your way without staying on all night. The Solar-Powered Motion Sensor Outdoor Light is powered by the pre-installed rechargeable battery, so you won't need to replace batteries constantly, and it will even work during power outages.
