Preferably, the solar battery panel is arranged on the rainshield.

The advantages of the present invention are:

1. Use the airbag to raise the light-emitting dot matrix composed of LEDs, and remind drivers far away to know the road conditions in time through the signs or characters displayed on the light-emitting dot matrix.

2. The structure is simple. Due to the use of the inflation and deflation structure, the warning ball takes up less space, and at the same time, the small volume can effectively prevent strong wind.
