【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 in the outdoors. 【Low Beam/High Beam Switching & 13 Lighting Modes】 This bicycle headlight features 3 modes: low beam, high beam, 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: Quickly press either button twice to activate. 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, one-piece molded 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 rain or snow, and withstands harsh weather and road conditions. 【Equipped with Lithium Polymer Battery & PSE Certified】 The bicycle light is equipped with a lithium polymer battery (2000mAh) equivalent to that of a smartphone. Compared to conventional lithium-ion batteries, it offers superior safety and stability, ensuring peace of mind even during long-term use. It has also obtained Japanese PSE certification and meets safety standards.
