Our docks can also be provided with safety spot lights for identification of the decking surface at night-time. The lights are made using optoelectronics, with high intensity, low consumption and low voltage power supply. Lights can be powered from the mains or from alternative sources. They are automatically managed via a control unit controlled by a twilight switch. As far as navigation signals are concerned, we have programmable night-time signalling devices with variable flows starting from a mile, with personalised flashing, which can also be powered from the electricity grid or alternative sources. Can be installed on the heads of the docks, on buoys and beacons.
