【Innovative Yellow/White Light Switching for Excellent Visibility】This bicycle light features two LEDs and allows you to switch between yellow and white light with a single touch. Yellow light provides superior penetration in bad weather conditions such as fog, rain, and snow, while white light illuminates a wide and bright area during night riding. With a maximum illumination distance of 300m, a 180° wide-angle beam, and a high brightness of 1000 lumens, it can be flexibly used depending on the weather and scene. It enhances visibility and safety, making it suitable for both road bike lights and cross-bike lights, from city streets during commutes to mountain roads in the outdoors. 【Near/Far Light Switching & 13 Lighting Modes】This bicycle headlight is equipped with 3 modes: near light, far light, and all-lights-on, which can be easily operated. High beam: Short press the upper button to switch between 5 levels: strong, medium, weak, flashing, and SOS. Low beam: Short press the lower button to switch between 5 levels: strong, medium, weak, flashing, and SOS. All-lights-on: Activate by quickly pressing either button twice. It supports 3 levels: strong, medium, and weak, and can be switched with either button. The memory function (excluding all-lights-on mode) allows it to restart with the previous settings. 【Durable Aluminum Alloy Body & IPX5 Waterproof Design】This bicycle light adopts a robust and durable aircraft-grade aluminum alloy and features a seamless, screwless design. It is resistant to shocks and vibrations, allowing for safe use on outdoor rides and unpaved roads. Furthermore, it is equipped with a 5mm thick waterproof rubber ring, achieving excellent IPX5 waterproof performance. 【Lithium Polymer Battery & PSE Certified】The bicycle light is equipped with a lithium polymer battery (2000mAh) comparable to smartphones. It offers superior safety and stability compared to conventional lithium-ion batteries, ensuring peace of mind even during extended use. It has also obtained Japanese PSE certification and meets safety standards. Furthermore, it supports convenient USB-C charging for easy and speedy charging. 【Compact, Lightweight, and Easy Installation】This bicycle light is lightweight at approximately 95g and compact, making it easy to carry. Installation is simple: fix the bracket to the handlebar, insert the main unit into the groove, and rotate it approximately 45 degrees until you hear a "click" to secure it firmly. It can be quickly removed during commutes, helping to prevent loss, and providing peace of mind. *This product includes a light bracket, and there is no need to purchase one separately.
