Outdoor Solar Powered Dock Lights and Wired Dock Lights that offer you lighting solutions for your dock. Most lighting options are solar powered LED lights that don't require wiring or running AC current over the water. Solar Lights must be placed in direct sunlight for as much of the day as possible. Lack of sunlight will result in poor charging and shorter run times, but will not cause dis-charge. Wired lights must be connected to a AC power source in order to operate.
