Review on 🚴 4000mAh Super Bright Bicycle Headlight - Long-lasting 9 Hours with USB Recharge, Waterproof Bike Light Set - Ideal for Night Riding, Mountain Bikes - 4 Light Modes - Suitable for All Bicycles by Steven Brouillard

The taillight was plain and simple, the headlight was oddly adjusted with NULL instructions. I still don't know what some of the parts are for and there are no instructions on how to care for the battery etc. The light is bright, has two stages which is nice, goes out about 20ft up... Tail light is ok and i like it flash setting. . but so disappointing, the company wants to sell in america but doesn't provide english instructions or at least pictures. I will not buy it again as I still have the parts and have no idea what they are for.
