This light does not require any button or coin batteries, making it an eco-friendly and hassle-free option. It is compatible with Garmin bike computers and brackets, as well as other devices that adopt the Garmin style. However, it is not compatible with the Garmin Edge 130 Plus, Edge TT/Tri Bar Mount, or the Wahoo ELEMNT BOLT V1 (WFCC3). For Wahoo compatibility, the original insert and mounting tab of FR160 must be replaced with QTM01 (sold separately). The wide-angle lens design of this bike light significantly enhances side visibility, especially at crossroads and roundabouts, increasing the chances of being noticed by passersby. The warning flash mode is designed to be eye-catching, with 3 steady modes and 3 flash modes to suit various riding situations. With a maximum brightness of 160 lumens, the FR160 is intended to increase visibility and can work as a backup light when combined with higher-lumen bike lights. It is not recommended to use it as a primary bike front light. This compact and waterproof bike safety light has an IPX6 water resistance rating, ensuring it stays functional even on rainy days. The bottom of the mounting tab is well-coated with aluminum alloy to withstand frequent installation. Weighing only 55g/0.12lbs, it is lightweight and won't burden your journey. Remember to tighten the charging port flap to maintain its waterproof integrity. For Wahoo bike computer compatibility, QTM01 is required (sold separately). It is recommended to use the included charging cable and standard 5V USB charging port for optimal performance.
