The Coast A8R rechargeable penlight is only 0.370” in diameter and 4” in length and can fit comfortably in a shirt or coat pocket. The rubberized pocket clip is easily removable and adjustable but stays firmly in place. It casts a nearly perfect circle of smooth and consistent light. Easy to charge, users can slip the Pro Flex Charging Cap over the head of the light and connect to an AC, DC or USB power source. The penlight has an aluminum body that is backed by Coast’s lifetime warranty against defects in materials and workmanship. This penlight includes a pocket clip.
