- SMART BIKE TAIL LIGHT WITH ANTI-THEFT ALARM: This innovative bike taillight doubles as a hidden anti-theft alarm. Equipped with a motion sensor and a 110dB vibration alarm, it effectively deters potential thieves, providing peace of mind when parked outdoors. Adjust the sensitivity easily across 7 levels, from gentle touches to more forceful impacts, to suit your needs. - AUTO BRAKE LIGHT FUNCTION: The built-in G sensor activates the rear light when you brake, illuminating for 2 seconds to alert drivers behind you. This feature significantly reduces the risk of rear-end collisions and enhances overall road safety. - ULTRA-BRIGHT LIGHTING WITH FOUR MODES: With a brightness of 160 lumens and a 270-degree visibility range, this rear light ensures you're seen day and night. Choose from four settings—Slow Flashing, Breathing, Fast Blinking, and Steady Light—easily controlled via a wireless remote for optimal visibility in various conditions. - AUTOMATIC ON/OFF FEATURE: The taillight intelligently activates in low-light environments thanks to its built-in light and motion sensors. In Slow Flashing and Breathing modes, it turns off after 30 seconds of inactivity to conserve battery. In bright conditions, it also turns off automatically. For daytime use, select Fast Blinking or Steady Light modes, which do not have the smart on/off function. - VERSATILE INSTALLATION OPTIONS: This bike light includes a mounting bracket and cable ties, allowing for two installation methods. The bracket is designed for standard tube positions, while zip ties accommodate irregular mounting surfaces. Installation is straightforward, making it a practical accessory for any cyclist. Use Cases: - Ideal for urban cyclists who frequently park outdoors and need added security against theft. - Perfect for commuters who want to enhance visibility while riding in low-light conditions. - Great for recreational bikers who appreciate the convenience of automatic lighting features and adjustable settings.
