The design using batteries and light makes the float perfectly visible at night, even from a long distance. The float flies very far and straight. The center of gravity was selected so that the float floats straight on the water, without leaning.

Appropriate dimensions of the battery socket ensure quick and easy installation. The lighting time on one battery is approximately 60 hours. The threaded and sealing ring design ensures water resistance.

The float consists of 3 printed parts, a light element from Aliexpress, cables, an O-ring sealing ring D33x1.5mm and a CR2032 battery.

You can color it according to your preferences, but remember that the light area should be made of transparent material.
