The SE Black Front and Rear Illuminated Beanie allows you to work and illuminate areas without the hassle, hands-free and without a flashlight. This compact sized item is handy to have in case of a blackout or emergency/survival situation. You can take it with you for boating, camping, car emergencies, fishing, walking the dog, and other outdoor activities. This item features lights that are easy to attach and remove. The lights have 4 x 200 lumens SMD bulbs. This beanie is made out of 100% acrylic and requires (4) CR2032 batteries, which are included. The beanie itself is great for cooler weather and to keep your head and ears warmer. Why mess with having to wear a hat AND a headlamp when you can have everything all in one!
