Abstract
Abstract A navigation lights device comprises red, green, and white navigation lights attached to the top of a left shoulder portion, a right shoulder portion, and a back side portion, respectively, of a buoyant vest or harness worn over the upper body of a person. A battery pack can be attached to the vest to provide electrical power to the navigation lights via wires that extend therebetween. The navigation lights device can be permanently attached to the vest or can be releasably attached. The navigation lights device also comprises headgear or a helmet that is worn over a top portion of a person's head and includes red, green, and white navigation lights attached to a left side portion, right side portion, and back side portion, respectively, of the headgear. The headgear can include a battery pack attached to the headgear to provide electrical power to the navigation lights via wires that extend therebetween.
