Flexible and lightweight, the Nite Ize BrimLit is a convenient, LED-powered hands-free light that clips easily and securely onto nearly any hat, cap, or visor brim. Formed from high-density EVA foam, the BrimLit slides underneath your hat’s brim and easily accommodates its shape. Its two spring-tension clips automatically adjust to the brim’s thickness, and a quick press of the button, activates the BrimLit’s four LED bulbs. Two light modes to choose from high mode for more directed light or low mode for glow. It is powered by two fully replaceable lithium batteries that are included. Measures 7" x 1¾". Weighs .16 lbs.
