During the day, these energy-efficient solar lights harness sunlight energy to charge their internal battery. At night they automatically turn on, emitting a soft glow for your fence post line.
Each Fence Post Cap is made of Premium Heat-Resistant Plastic for years of use. With our Newest & Improved Solar Panels and 5 LEDs, the lights will provide longer illumination (up to 8 hours) and double the brightness with two pre-installed rechargeable batteries.
