There are sailboats and seagulls in the sea. What is the meaning of safety light?

The lamp symbolizes the patron saint, the sun symbolizes the firm and persistent hope for eternal peace, and sailing in the sea means good luck and smooth sailing, so it means smooth sailing.

Safety lights are ever-burning lamps used to pray for blessings. Their significance lies in immortality, and they are mostly used in ancestral temples. Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
