The lighthouse project was created by a group of young men confronted by that fact that suicide kills more young men than anything else, and that this number is rising.
They wanted to shift the responsibility from a guy who needed to talk, to the many mates willing to listen. The lighthouse is designed to be a tattoo, real or temporary.
When you wear the mark of the lighthouse, you are identifying yourself as a safe place for a mate to talk. You’ll be there to listen and look out for him.
