Review on 🚴 Seianders Rechargeable Bike Lights Front and Back, 5500 Lumen Super Bright Bike Headlight, 6 Light Modes, IPX-6 Waterproof, Portable Household Flashlight, Suitable for All Mountain and Road Bikes by Alejandro Lane

Both these bicycle lights and taillights are very bright and easy to use. The swivel function allows the headlight to be used on the handlebars where there is no straight section for mounting. Be careful to turn the headlight clockwise so as not to loosen the inner nut bolt. This happened to me so I disassembled the mount by removing 2 small screws and tightening the Allen screw. It worked great! The rest of the headlight is great. The backlight is good, but you have to go through the settings to find the flashing red light. It is slightly different from the front light. But once you get it... It looks amazing. If you are cycling at night or early in the morning... These lights help a lot because you can be seen!
