This device is a multi-function amber warning beacon with dual charging capability (solar and USB), built for reliable safety signaling in outdoor and mobile environments.
From a design perspective, it combines a high-transparency amber dome lens with a robust black base, giving it strong visibility while maintaining durability. The integrated solar panel on the top allows it to continuously recharge during daylight, while the USB interface ensures stable power input when solar charging is insufficient.
When activated, it emits a bright flashing amber signal that can be easily recognized from a distance, helping to alert and guide traffic or pedestrians in potentially hazardous situations. Its compact, self-contained structure makes it easy to deploy without complicated installation.
It is especially suitable for roadside emergency marking, construction warning zones, vehicle breakdown alerts, and temporary traffic control, where portable and dependable warning lighting is required.
