Most house numbers are virtually impossible to see at night. Whether you're waiting for food delivery or expecting guests, clear viewing of your address is extremely helpful. With the EZView Solar Powered Address Numbers, you'll never again have to worry that service people or even emergency personnel will be able to locate your house. Using only solar energy, the numbers light up each evening and turn off at dawn, without electricity or help from you, ever! You will need to purchase a separate kit for each number in your address.
