Description: This taillight is the latest turning taillight, which integrates and optimizes the characteristics of many products on the market. Here I will roughly say the following differences. For details, see the picture introduction. In terms of battery life: Our battery is a 2000 mA large capacity battery, which kills 99% of the taillights in the market, and its battery life can reach the super-long battery life of 20 hours long and 45 hours slow. Charging indicator light: There are different indicator lights for fully charged and charging. Remote control: We are equipped with three remote controllers, the main remote controller and two sub-remote controllers. The sub-remote controllers respectively control the blinking of the left and right turn signals, thus solving the risk of pressing the wrong button, and facilitating the operation and giving instructions faster. Luminous modes: We have eight luminous modes, which basically meet the flash needs of most people. Installation mode: We have two sets of installation bases, one is cushion type and the other is sitting bar type. You can choose freely. Waterproof test: We have also achieved waterproof life, and there is no big problem in rainy days. (It is recommended not to use it in rainy days as far as possible. Because there is a usb port and a light sensing port at the bottom, there is a risk of long-term soaking and water leakage.)
