We are pleased to offer the new and improved flashing sunglasses. Each pair of sunglasses has 10 super bright micro LED lights that emit a bright and powerful shine. Each pair of sunglasses is equipped with 3 x AG-13 batteries which increase shelf life and dramatically increase flash output. Whats more, these glasses are actually comfortable to wear due to the new ergonomic design. The Flashing LED sunglasses have a 3 position switch: Off, Steady-On, Flashing (fast) and Flashing (medium)
