These Solar pathway lights are weatherproof and perfect for illuminating pathways and walkways, docks and decks. An integrated solar cell located on the top of each light recharges the included NiMH battery. An internal sensor ensures the light turns on at night. Stainless steel construction is resistant to wear and corrosion. These lights are great for safety lights along the edges of deck or docks and creating a perimeter line along driveways. LEDs are more durable than conventional glass light bulbs and are more efficient.
