Bike Tail Light with Turn Signals, Brake Light, Horn & Alarm-USB-C

This multifunctional 5-in-1 Smart Bike Rear Light combines an electric horn, anti-theft vibration alarm, rear bike light, turn signals, and automatic brake light into one compact device. It enhances your visibility, improves safety—especially during night rides—and adds reliable protection for your bike. With five essential features in one unit, you save space, reduce clutter, and get an affordable, practical cycling accessory.

Equipped with 31 high-end LEDs delivering up to 160 lumens, this rear light offers wide-angle illumination that helps motorists spot you day or night. Easily switch between six lighting modes using the remote:

• Slow Flashing
• Breathing
• Fast Blinking
• Steady Light
• Emergency Light
• Off

Activate left or right turn signals using the handlebar-mounted remote. Each signal flashes with a click sound—just like a car—letting nearby drivers and pedestrians clearly see the direction you intend to turn. Prevents forgetfulness with easy on/off control.

A built-in motion sensor automatically triggers a bright brake light for 2 seconds when you slow down, alerting riders and drivers behind you. This feature helps prevent rear-end collisions. Note: Brake-light detection is not active in emergency mode.

Protect your bike with a sensitive vibration-activated alarm. Choose from 7 sensitivity levels—from light touch to strong impact— to deter thieves effectively. Arm the alarm after parking and keep your bike secure anywhere you go.

The integrated horn emits a loud 110 dB alert, ensuring others notice your presence. Choose from three volume levels and three sound types: electric car horn, standard horn, or birdcall.

In Slow Flashing and Breathing modes, the tail light automatically adjusts based on environmental lighting and movement:

• Turns off after 30 seconds of no movement in dark environments
• Reactivates when motion is detected
• Automatically turns off in bright conditions to save power

No need to worry about the light turning on at night while you sleep.
