Signal lamp
A signal lamp is a special kind of light that helps people communicate with each other from far away. It looks like a big flashlight, but it has colored lenses that can be turned on and off to send different messages.
Imagine you're playing a game of capture the flag with your friends, but you're on different sides of a big field. You can't talk to each other because you're too far away, but you can use a signal lamp to send secret messages!
If you want to say "go left," you would turn on the green light and point it to the left side of the field. If you want to say "wait," you would turn on the red light and then quickly turn it off. Your friends will be watching for your signals and will be able to see what you're saying, even from far away!
Signal lamps were first used by sailors a long time ago to communicate between ships, and they're still used today by soldiers, pilots, and other people who need to talk to each other from far away. It's kind of like having your own secret code that only you and your friends know!
