Tick Tock Plank / Stair safety bump

Tick Tock Plank

When people who lift something go up and down the stairs in condition of not securing a view, they may lose their footing.
So they need a kind of alarm that makes people perceive both beginnings and endings parts of stairs.

"Tick Tock Plank" will help people notice both parts of stairs by making a sound like the Air horn.
