The Einstein 500 Headlamp lets you walk, create, read, navigate, and more -- easily and hands-free! This portable yet powerful headlamp provides 5 light settings that include turbo, high, medium, low, and red (which better assists with night vision). It is water-resistant and fully adjustable, so you can enjoy a comfortable, perfect fit every time you use it. The light easily tilts so you can be sure the light is directed at the angle you need it. 3 AAA batteries are included.
