Maximum Safety with Intelligent Brake Sensor: CYCLAMI tail lights feature an advanced brake sensor that automatically increases brightness to 200 lumens when slowing down, significantly improving visibility to following vehicles. Nighttime visibility range of up to 100 meters ensures safety in low light conditions. Seven easy-to-switch lighting modes: Seven lighting modes—Strong (200 lumens for nighttime use), Eco (50 lumens for daytime use), and Flashing (for emergencies)—can be quickly switched with the push of a button. From urban areas to mountainous terrain, the Strong mode provides visibility up to 100 meters. Fast USB-C Charging and Clear Autonomy: Built-in 600mAh battery fully charges in just 3 hours via USB-C. Up to 8 hours of use in Strong mode and up to 23 hours in Eco mode. The indicator makes it easy to monitor the charge level and prevent unexpected interruptions. We recommend fully charging the device before first use to activate its full capacity. If you do not use the device for a long period of time, we recommend charging it every 3 months to maintain its lifespan.
