[High-Intensity LED & Brake Sensing Advancement] Illuminate your surroundings with our rear bike light's high lumen COB LED, featuring smart sensor technology that activates a brake light when you slow down. The light emits a high-intensity flash for 5 seconds, alerting riders behind you for enhanced safety.

[Dynamic Modes & Easy Install] Choose from 4 dynamic light modes: (1) Normal Flash, (2) Breathing Flash, (3) Fast Flash, (4) Steady On. Tailored for diverse riding conditions day and night. Effortlessly install with metal under-seat or rubber band seat post mounts. Fits road, mountain, cruiser, scooter.

[Smart Auto On/Off & Battery Efficiency] Experience intelligent functionality with our bike rear light. Equipped with Motion and Light Sensors, it automatically turns off after 30 seconds of inactivity. Once movement is detected or your bike is in motion, the light reignites (auto on/off applies to modes 1 and 2). For continuous daytime visibility, opt for modes 3 or 4 to bypass the Light Sensor (Brake sensing active in all modes).

[Extended Battery Life & Intuitive Power Display] Stay powered during your rides with the 400mAh Li-ion battery. On a full charge, enjoy up to 50 hours of usage. The built-in power indicator features four blue breathing lights, each indicating 25% battery capacity, ensuring you know when to recharge.

[Durable Build & All-Weather Ready] Crafted from premium aluminum alloy, our bicycle brake light boasts an elegant metallic finish. Designed to withstand diverse weather conditions with an IPX6 Waterproof rating, making it suitable for any ride. ROCKBROS GUARANTEE: Backed by a 12-month guarantee, a 30-day money-back guarantee, and 24/7 customer support, ensuring your purchase is riskless.

In the package, you will find two mounting brackets (one under seat and one seat post), a type C USB charging cord, an English manual, and the bike back light itself. The USB port is located between the light and rack, requiring you to remove the tail light from the rack to charge it.

The brake feature is quite sensitive, activating with even light braking. It comes on as soon as it senses your bike slowing down. There are 4 modes, and the brake light feature must be on for it to work. There is no low or dead battery indicator on the handlebars, but the 4 small blinking blue dots in the center provide a battery level display, with all 4 blinking indicating 100% charge, 3 blinking for 75%, and so on.
