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 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. 【Low Beam/High Beam Switching & 13 Lighting Modes】 This bicycle headlight is equipped with 3 modes: low beam, high beam, and all-on, which can be easily operated. The memory function (excluding the all-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.
