When you need to warn
approaching drivers of imminent danger or a hazard in or near the road, simply squeeze the button.
The Amber Triangle will start flashing, warning oncoming drivers to slow down and use caution. After 60 seconds the HAWL will automatically shut itself off. This time frame, 60 seconds, tells oncoming drivers who see HAWL's flashing triangle, that they need to be aware of a potential hazard laying in their path from that point, up to approximately one mile ahead, depending on posted speed limits.
