The LED Hat Light from BrimLit is a simple clip-on light that you tack on to any hat or cap, or even a visor brim. It’s a great way to get some hands-free portable illumination going while you’re in the outdoors at night, or inside a garage without a light. The LED Hat Light is a perfect travel companion while you’re out camping or hiking. It’ll help you see what’s in front of your nose without throwing a bright light all over the place that disturbs the wildlife. By the same token, it’s not powerful enough to be a headlight while you’re biking, but it does shine brightly enough to serve as a safety light. It needs two replaceable batteries, and has high and low modes. You get a runtime of 8-16 hours depending on the mode.
