This module allows for the control of hazard warning lights, pedestrian crossings, and railway crossing safety systems. Due to its small size, this module can fit into almost any hollow space on a model railway. Other applications include installation in emergency vehicles and locomotives (for example, to indicate shunting operations). It can also be used to create a construction site on a bridge. It can also function as a simple flasher. Two outputs are alternately switched on and off (approximately 1 Hz). Light-emitting diodes (up to two per output) can be connected directly to the outputs.
