RAVEMEN CL06 Bicycle 50 Taillight with Brake and Light 500mAh 30 Hours of Battery 4 COB 7 Dimming IPX6 Day and Night for Road and Cross PSE Direct

[Brake & Light Sensor Mode] The built-in brake sensor will activate a 3-second warning flash when the brake sensor detects deceleration while the light is on. The light sensor also detects headlights from a vehicle approaching from behind (50 lux or higher), and will activate a 5-second warning flash to alert drivers behind. While the light is on, click the light sensor button to enter light sensor mode (the pilot light will turn blue). Note: Light sensor mode is designed for night driving only; do not use this function during the day to avoid unnecessary power consumption. [7 Lighting Modes & Up to 30 Hours of Light] Simply press the power switch to turn the light on and off or switch between 6 modes (warning flashing mode requires light sensor mode or brake mode). Runtime: High mode (approx. 8 hours), Low mode (approx. 18 hours), Rapid flashing (approx. 30 hours), Pulse flashing (approx. 12 hours), High/Slow flashing (approx. 16 hours), Low/Slow flashing (approx. 28 hours). [USB-C Rechargeable with Battery Level Indicator] Equipped with a built-in 500mAh lithium-ion battery, you don't have to worry about running out of power in a short time. A USB-C charging cable is included, so the tail light can be recharged repeatedly. Easily charge at home or outdoors. It also features a pilot light that indicates the battery level, making it easy to know when it's time to charge. The light flashes red when charging, and remains solid red when fully charged. When the battery is low, it automatically switches to low/slow flashing mode to conserve power (this can last for approximately one hour). [Easy Installation & Adjustable Angle] The clip-on design allows for easy installation on the seat post, preventing the light from falling off (no need to worry about loosening the screws). The light's angle is also adjustable, so adjust it for maximum visibility before use. It can be attached to both standard and irregularly shaped seat posts. It can also be attached directly to certain helmets and backpacks. [High-quality materials and IPX6 waterproof rating] The front and body are made of aluminum and hard anodized, while the rear is made of resin and fiberglass materials. This light offers protection from drops and friction, excellent heat dissipation, and a luxurious feel. Its IPX6 waterproof rating means you can use it safely even on rainy days. The USB-C charging port is located at the bottom of the tail light and has a waterproof cover to prevent the USB charging port from getting wet. (Do not immerse in water.)
