【Excellent Visibility with Innovative Yellow/White Light Switching Function】 This bicycle light is equipped with two LEDs and allows for one-touch switching between yellow and white light. 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, working as both a road bike light and a cross-bike light, from city streets during commutes to mountain roads for outdoor adventures. 【Near/Far Light Switching & 13 Lighting Modes】 This bicycle headlight features 3 modes: near light, far light, and all-lights-on, which are easy to operate. ✅ High Beam: Short press the up button to switch between 5 levels: strong, medium, weak, flashing, and SOS. ✅ Low Beam: Short press the down 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 using either button. ✅ 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 screwless, integrated 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. It provides stable illumination, regardless of harsh weather conditions or road surfaces, even on rainy or snowy days. 【Equipped with 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.
