Designed for outdoor use, this solar-powered warning and safety light provides a bright RED LED light source. Features both FLASHING and CONSTANT-ON modes (selectable by the user from an waterproof switch on the base underside). The attached mounting bracket makes it easy to install this lamp where needed. The bracket secures the lamp to items up to two inches in diameter. You may also remove the bracket and attach the lamp using the bracket mounting lug if needed. Fully waterproof and weatherproof, this device charges during daylight hours and automatically turns on at dusk. A high capacity internal battery ensures all-night operation. A reflective RED tape at the lamp base helps ensure visibility. Available in other colors, see our other listings on Amazon for other options.
