A base member has a top and a bottom with laterally spaced sides, a generally planar front face, and a generally planar rear face. A battery extends through a cylindrical hole through the base member. A lens cap is threadedly coupled to the rear face of the base member rearwardly of the hole to create a light chamber rearward of the base member. A battery switch is threadedly coupled to the base member. A printed circuit board with rearward facing LEDs is within the chamber. The LEDs are adapted to be turned on and off through the energizing and de-energizing of the battery by the switch.
