Abstract: A dock light for mounting in a void in the side of a floating dock. The light has a housing with a floor, sidewalls, lens and lid defining a chamber. The chamber houses a power source, such as a battery and photovoltaic cell, and a light source, such as a light emitting diode (LED). The lid is removably mounted to the sidewalls, and is flush with, or set beneath, the top surface of the dock when in an operable position. The lens extends from the void at a side opening when the dock light is in an operable position, and is flush with, or set beneath, the side surface of the dock. The light shines from the side of the dock, and is powered by collecting energy from the sun, thereby requiring little to no maintenance. The dock light is protected by the surrounding surfaces of the dock.
