【5-in-1 Ultra-Bright Bike Taillight】This 5-in-1 remote-controlled bike taillight combines a warning light, brake light, turn signal, electric bell, and anti-theft vibration alarm into one versatile device. Equipped with 31 high-end LED lights, it delivers an ultra-bright output of up to 160LM, ensuring your safety while cycling in foggy, rainy, or dark conditions. With six lighting modes—Slow Flashing, Breathing, Fast Blinking, Steady Light, Emergency Light, and OFF—you can easily switch modes using the remote control. It’s the ultimate safety accessory for your cycling adventures. 【Brake Light & Turn Signals with Automotive-Style Sound】This bike taillight offers advanced turn signals and brake light functions. When you press the right or left turn signal button before turning or changing lanes, the corresponding light illuminates and emits an automotive-style turn signal sound, providing a clear alert to others and reminding you to deactivate it after completing your turn. The brake light automatically shines brightly for 2 seconds when you brake or slow down, warning those behind you. Additionally, the warning light activates automatically during night rides or when passing through tunnels, ensuring maximum visibility and safety. 【Vibration Alarm, Bike Horn & Search Function】The bike taillight features a powerful anti-theft vibration alarm with a loud 110dB sound, effectively deterring thieves and attracting attention. It offers 7 levels of adjustable sensitivity, ranging from a gentle touch to a firm push or beat, allowing customization to suit your needs. The built-in bike horn provides 3 selectable sounds, which can be easily triggered via the remote control. When the electric bell button on the remote is pressed, a sharp 110dB horn sound will emit from the taillight, not only alerting others but also helping you quickly locate your parked vehicle. 【Power-Saving Smart Auto On/Off】In intelligent mode (Slow Flashing/Breathing), the taillight automatically adjusts its operation based on ambient brightness and riding activity. In dark environments, if the bike remains stationary for over 30 seconds, the light will automatically turn off to conserve power. Once the bike is in motion again, the light will automatically turn back on, activated by vibration. This smart and energy-efficient design ensures optimal performance while maximizing battery life, making it an ideal choice for a reliable bicycle tail light. 【IP65 Rated Waterproof & Rechargeable】Equipped with a 3.7V 2000mAh rechargeable battery, this bike tail light provides up to 70 hours of runtime in blinking mode after a full charge. The remote control uses a replaceable CR2032 coin cell battery, lasting 3-5 years with typical usage (30 activations per day). A battery indicator notifies you of the charging status and power level of the taillight. With an IP64 waterproof rating, this bike light is suitable for use in light to moderate rain and operates reliably in temperatures ranging from -4°F to 140°F, ensuring dependable performance in various weather conditions.
