What Our Gearhead(R) Experts Are Saying:"I've been using the FR500 for my evening rides, and it's incredibly efficient. The 500-lumen beam is plenty bright for dark roads, and I love how it tucks neatly under my Garmin mount-no extra clutter on the bars. The auto on/off and power bank feature are super convenient, especially on longer rides."The Ravemen FR500 Headlight brings sleek design and dependable brightness to your daily rides. With 500 lumens of high-output illumination, it lights up dark roads and enhances visibility during the day with multiple flashing modes. Designed to fit directly beneath your Garmin or Wahoo bike computer, it keeps your cockpit clean while combining lighting and mounting into one efficient setup. The FR500's intelligent motion sensor automatically turns the light on when you start riding and off after two minutes of stillness, conserving battery life without the need for manual toggling. A 2000mAh rechargeable battery powers up to 36 hours of runtime and doubles as an emergency power bank for your cycling computer. Durable, waterproof, and crafted with an aluminum heat-dissipating body, the FR500 ensures visibility and reliability for every ride, rain or shine.
