The light wire does not react well to bending. The constant opening and closing of the sunglasses arms will cause the light wire to stop working. For this reason, the frame arms are permanently bonded into the open position…
Each pair of shades comes with a battery pack with a button that controls 5 modes (off, fast flowing, slower flowing, even slower flowing, slowest flowing). The glasses have a 4 foot wire coming off the back of the left hand frame arm and runs to a small battery pack. Typically, you’d run the wire under/through your wardrobe and place the battery pack in your pants/shorts pocket. The small battery pack uses two AA batteries (not included) and lasts over 12 hours of continuous use.
