It's never been easier to illuminate steps, railings and deck edges, helping increase visibility and prevent falls and trips—thanks to these LED Solar Deck Lights. During the day, their solar panels convert natural sunlight into electrical energy, storing in the rechargeable battery to automatically activate the solar powered light bulbs at sundown. Helping increase your family's safety without wiring, fuss or soaring electric bills, the LED lights are encased in weather-resistant plastic housing and include wood screws for easy installation. Set of 3. Each, 3 1/4" x 1 3/4" x 1 3/4".
