Bike Alarm Taillight with Electric Bell, Anti-Theft Bicycle Taillight with Turn Signals and Automatic Brake Light, Remote Control Bike Rear Light USB Rechargeable Safety Warning Cycling Light, 3 Pack

The 5-in-1 bike taillight features a variety of personalized settings, making it a more comfortable choice for cyclists. The taillight includes the following functions: warning light, brake light, turn signal, electric bell, and anti-theft alarm.

The bike alarm taillight is powered by an 18650 3.7V 2000mA battery, which can provide a standby time of 4 to 8 months. The taillight is charged via a standard USB-C 5V port. The remote control, on the other hand, uses a CR2032 button battery with a standby time of 3 to 5 years (30 times per day).

The working frequency of the system is 433.92MHz, with a wireless range of 30 to 60m. The device can operate in a temperature range of -40°C to +70°C and a humidity range that is not specified.

The installation of the bike alarm taillight involves the following steps: 1. Place the silicone ring on a suitable location on the seat post. 2. Insert the taillight bracket into the silicone ring, align the contours, and secure it with a screw. 3. Insert the bike alarm taillight into the taillight bracket.

The installation of the remote control involves similar steps: 1. Place the silicone ring on a suitable location on the handlebar. 2. Put the remote bracket around the silicone ring, align the contours, and secure it with a screw. 3. Press down and turn the remote counter-clockwise until it locks into place.

The 5-in-1 ultra-bright bike taillight features 31 high-end LED lights, providing up to 160 lumens of brightness to enhance safety during cycling in foggy, rainy, or dark conditions. The taillight offers six lighting modes that can be easily selected using the remote control: slow flashing, breathing, fast blinking, steady light, emergency light, and off.

The brake light and turn signals come with a clicking sound to alert others when turning or changing lanes. The brake light will automatically highlight for 2 seconds when braking or slowing down. The warning light will automatically turn on when passing through a tunnel or during night rides.

The taillight also includes a vibration-triggered anti-theft alarm with a maximum volume of 110 dB, effectively scaring off potential thieves and attracting attention. The sensitivity of the alarm can be adjusted across seven levels, from gentle touch to heavy impact. Additionally, the taillight features a bike horn with three selectable sound options, allowing you to remind people of your presence.

The taillight is designed with a power-saving, smart auto on/off feature. In the intelligent mode (slow flashing or breathing), the light will automatically turn on or off based on the ambient brightness and whether the bike is in motion. If the bike is stationary for more than 30 seconds in a dark environment, the light will turn off to conserve power, and it will automatically light up again when the bike is in motion.

The IP64-rated taillight is waterproof and rechargeable, with a 3.7V 2000mAh battery that can run for up to 70 hours in the blinking light mode after a full charge. The remote control, powered by a replaceable CR2032 coin cell battery, can operate for 3 to 5 years (with 30 uses per day).
