Quickly position these portable flashing lights using the magnetic base to draw attention to hazards in areas such as docks and railroad crossings. They are battery operated, so they do not need to be wired or plugged in. When they are mounted in hard-to-reach places, use the remote control to operate the lights up to 150 ft. away. The long-lasting LED bulb means these lights do not require frequent maintenance. Rated IP65, they resist dust and light rinses.
