Solar Dock Dots are the smallest dock solar lights available! A flush mount makes them virtually unnoticeable during the day and offer an ambient glow at night. A super bright LED and powerful solar panel provide the solar dock dots with an impressive illumination. Dock Dots are the perfect and easy way to light up the dock, stairs, or deck. The dots come with 4 user-replaceable 1/3 size AAA batteries. Easy to install in minutes using a 1-3/8" drill bit.
