Fosmon’s Bike Tail Light Alarm is a 5-in-1 device combining a Warning Light, Turn Signals, Auto Brake Light, Bike Horn, and an Anti-Theft Alarm. The device comes with a user-friendly remote control powered by a durable CR2032 battery and offers a wireless range of up to 60m/196ft. The rear light features 6 lighting modes (Slow Flashing/Breathing/Blinking/Steady/Emergency/OFF) with LED lights emitting up to 160 lumens. It has a built-in accelerometer that automatically highlights the light in red for 2 seconds when brakes are applied to avoid rear-end accidents (except during Emergency/OFF). The alarm function has 7 sensitivity levels and can be easily adjusted. Simply press the Arm button on the remote to activate the alarm system. In Arm mode, the device emits a loud 110dB sound when it detects vibration and helps to deter theft. The bike taillight is made from durable PC + Anti-UV material with an IP65 waterproof rating, providing protection against sunlight, water splashes, and dust. The intelligent lighting mode (Slow Flashing/Breathing) ensures power-saving auto ON/OFF with motion and ambient light sensors. It automatically turns ON in dark environments or when motion is detected, and turns OFF in bright environments or when no motion is detected. The left/right turn signal is accompanied by a clicking sound that acts as a blind spot assistant in busy areas, while the 110dB loud electric bell with 3 ring tone options (Standard/Electric Car/Birdcall) can be easily activated to alert others of your presence while riding. Both functions can be conveniently controlled through the remote control.Specifications: Max Light Output: 160 Lumens, Number of LEDs: 31, Bike Tail Light: 6 lighting modes, Audible Turn Signals: Left/right turn signals with clicking sound, Auto Brake Light: Built-in Accelerometer Sensor, Anti-theft Vibration Alarm: 7 adjustable sensitivity, Electric Bell Bike Horn: 3 ring tones, Bike Alarm/Horn Noise Level: 110dB, Waterproof Level: IP65, Remote Wireless Range: 30 – 60m (98 - 196ft), Mounting Bracket Diameter (Remote): 0.91 – 1.34 inch (23mm - 34mm), Mounting Bracket Diameter (Taillight): 1.06 - 1.57 inch (27mm - 40mm), Working Temperature -40°C ~ +70°C, Storage Temperature: -40°C ~ +70°C, Working Humidity:
