Description

Technical Field

[0001] This utility model relates to the field of warning device technology, specifically a portable flexible warning device. Background Technology

[0002] Arrow lights are widely used in the field of traffic safety. They can be used on directional signs, traffic intersections, or road construction vehicles to convey information to people and vehicles around them, reminding them of the surrounding road conditions, allowing them to adjust their speed appropriately, choose the right road to travel, avoid traffic jams, and at the same time ensure their own safety and save time.

[0003] Engineering vehicles, such as water trucks, travel slowly when operating, and surrounding vehicles will try to overtake them. However, water trucks generally spray water on both sides, which poses a risk of traffic accidents during overtaking. Usually, water trucks are equipped with arrow lights to indicate that the water truck is about to turn, and surrounding vehicles will give way according to its driving status.

[0004] During road clearing and rescue operations, tow trucks need to tow or carry disabled vehicles. During this process, the rear arrow lights of the tow truck are often obscured by the disabled vehicle, rendering them ineffective. Currently, magnetic flashing lights are attached to the tow truck to warn following vehicles, but these often fail to achieve the desired warning effect and can easily cause secondary accidents during the rescue process. Therefore, this invention provides a portable, flexible warning device. Summary of the Invention
