Sector light

Imagine you're standing in front of a big building with different doors and windows on each side. You want to make sure boats and ships sailing by in the water can see the building from far away so they don't crash into it. That's what a sector light does – it helps boats and ships see important buildings and landmarks from the water.

A sector light is like a flashlight that shines a bright beam of light in a certain direction. This light helps boats and ships know where they are by shining on different parts of a building or landscape. The light beam is very strong and can be seen from a long way off in the water.

The sector light usually has different colors that show sailors where they are in relation to the building or landmark. One color means they are on the right side of it, while another color can mean they are too close or too far away. Sailors need to pay attention to these colors and make sure they stay in the right area so they don't run into anything.

Overall, the sector light is like a giant flashlight that helps sailors know where they are when they're out on the water. It shines bright colors and lights up important buildings and landmarks, so sailors can navigate safely and avoid accidents.
