Abstract: A waterproof lens switch assembly for a lighting unit is provided. The waterproof lens switch assembly includes a cylindrical metal lighting fixture which includes a screwed-on ring, a protective lens, a transparent flexible cover, an electrical on/off switch and at least one LED lamp. The ring and the flexible cover together create a waterproof seal for the waterproof lens switch assembly. The transparent flexible cover and the clear lens both allow light to pass through, and the transparent lens protects the flexible cover. When depressed by a user, the lens pushes the flexible cover onto the on/off switch and turns the light on or off. The LED lamp illuminates when turned on, and provides illumination through the flexible cover and the lens, respectively.
