Fitting the cordless gutter solar light is as easy as hanging up a jacket. Simply clip it over the edge of the gutter and the job is done. There’s no drilling required, no wiring to worry about, and no need for any tools at all. With absolutely no running costs, its solar panel on top recharges the included batteries during daylight hours. An automatic sensor turns it on at dusk and off at dawn, lighting its LEDs for up to 8 hours. Featuring three high-intensity super bright LEDs, it's weather resistant for use over doorways, garages, paths, driveways, patios, and balconies, in fact anywhere and everywhere you need the safety and security of bright outdoor lighting.
