1: Long press for about 2 seconds to turn on and off, short press to change segments, a total of 7 modes. It defaults to smart mode when it is turned on. Press the switch 3 times quickly to switch between normal and smart modes. The green light on the switch will stay on for 3 seconds to indicate it has entered normal mode. The brake light will stay on for 3 seconds to indicate it has entered smart mode. Note: Switching between normal and smart modes can only be operated through the key switch.

2: After being turned on and unlocked for the first time, the product automatically turns on the receiving function through the vibration switch signal to realize remote control synchronous operation while riding. When dynamic conditions are detected, remote control power on and off and steering brake operations can be realized. In the stationary state, the signal reception function will be turned off after about 5 minutes.

Three: Smart mode, when turned on to detect strong light conditions, it will sleep for about 90 seconds without any button operation. It automatically turns on when dynamic signals are detected when the light is dark, and sleeps for 90 seconds in a static state, and the vibration resumes.

Four: In normal mode, the light status is not affected by vibration and light, and the remote control can operate normally when a vibration signal is detected.

Five: When charging, the red indicator light of the single-color model moves forward (the blue indicator light of the colorful model moves forward), and turns off after charging. Note: It cannot work while charging.

Good safety device

I use this product on my electric bicycle as a supplemental safety device. It works great and is visible for a good distance to the rear.

Terry Shiver
You see me now!

Smart brake light is as advertised. It¡¯s quite visible during daylight and very visible at night! Battery is quite strong evidenced with me having it on high settings for over three hours and with more left in the tank. Drivers have actually mentioned how they saw the brake light come on from a distance, and was alerted to what I was doing.

Great brake light!

Auto senses braking, and lights up brightly in red. Steady or flashing pattern helps make you more noticeable at night.
