If that UPS guy keeps complaining about finding the address on your house, here's a simple—and green—way to make sure it never happens again. From Smarthome comes the Solar Address Light, a piece of signage that will illuminate your address using solar power. The 4-inch numbers should be visible from up to 500 feet in the dark and it takes just 4 hours of sun to power it for 3 nights. Basically works with a built-in light sensor that will realize when it gets dark and duly activate the lights to go on—turning them off when the sun comes up. And if you want to put the sign in a shady area, the solar panel can be detached and moved up to 8 feet away. Just $50.
