Easy installation and replacement If your knit beanie already has an LED module, simply remove the broken lamp and insert this LED light lamp as a direct replacement. If your hat does not have an LED, cut the hat fabric to the shape of the light, sew on the included leather traps, and install the lamp pocket. The leather traps are included and can be sewn onto most knit hats to secure the lamp for hands-free lighting. USB rechargeable and convenient charging Standard USB charging: plug into any standard USB port—car charger, computer, wall adapter, or portable power bank. Charging indicator: red light while charging and green when fully charged, for straightforward monitoring. Adjustable brightness and reliable performance Three brightness modes: strong, medium and weak to match different lighting needs. Single center button to turn the light on/off and cycle brightness levels. Easy to use and clean Simple push-button control makes mode changes quick, even with gloves on. To wash the beanie, gently remove the lamp cap from the lamp housing and wash the hat separately.
