The Halo Light is an uninterrupted ring of light that is worn around a hard hat. The ring can be seen from a distance of 400 metres. On the one hand it improves visibility, and on the other it heightens safety since it can be seen from all sides. Due to its robust design, the ring can withstand mud, dust and rain, and it is also energy-efficient. Four different operation modes are available, which allows the light to adjust to any given situation.
