The term 'Good Luck Bringer' can refer to two different objects: a horseshoe and a shooting star. A horseshoe is an iron or steel U-shaped object that is hung above doorways as a symbol of good luck. It is believed that the horseshoe will bring good fortune to those who pass through the doorway. A shooting star is a meteor that streaks across the night sky, often seen as a sign of good luck. Both of these objects are seen as symbols of good luck and are believed to bring good fortune to those who witness them.
