Yellow light provides excellent penetration in bad weather such as fog, rain, and snow, while white light illuminates widely and brightly during night riding. With a maximum irradiation distance of 300m, a 180° wide-angle irradiation, and a high brightness of 1000 lumens, it can be used flexibly depending on the weather and scene. It enhances visibility and safety, working as a road bike light or a cross bike light, from city streets during commuting to mountain roads outdoors. 【Low Beam/High Beam Switching & 13 Lighting Modes】 This bicycle headlight is equipped with 3 modes: low beam, high beam, 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 the 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 screwless, integrated design. It is resistant to shocks and vibrations, allowing you to use it with confidence on outdoor rides and unpaved roads. 【Lithium Polymer Battery & PSE Certified】 The bicycle light is equipped with a lithium polymer battery (2000mAh) equivalent to that of a smartphone. It is safer and more stable than conventional lithium-ion batteries, ensuring peace of mind even during long hours of use. It has also obtained Japanese PSE certification and meets safety standards. Furthermore, it supports convenient USB-C charging, allowing for easy and speedy charging. 【Compact, Lightweight, and Easy to Install】 This bicycle light is lightweight and compact, weighing approximately 95g, making it convenient to carry. Installation is easy: fix the bracket to the handlebar, insert the main unit into the groove, and rotate it about 45 degrees until you hear a "click" sound to secure it firmly. ※ A light bracket is included with this product, and there is no need to purchase one separately.
