We love to go and see the lights in the town, but the best lights are when there is a festival on. People come in and set up lights that turn the night into day.

If you look out at the town at night, you see lights in all of the houses and shops. Lights mean that we can still do things after dark.

What if the lights all went out one day? It would be a very different world. You could not see well at night. You might get scared.

We would not be able to do very much at night. It would be like medieval times. We would have to live by the sun.

The road are only safe to drive at night because we have lights to guide the way. We can see other cars and bikes. We can see where people need to cross.

If the lights went out, the roads would be a mess. Cars would hit each other and people would get mad. You could not get far.

Lights can bring us a lot of joy as well. It is so fun to go to a carnival at night. We can go on the rides and play games to win toys!

There can be no rides if the lights go out. If the power is off, it stops a lot of things from working. No more carnivals.

A lighthouse is one way that lights keep us safe. Ships need lighthouses to show them where to go. They need to keep clear of rocks.

If there were no lights, a ship would not know when it needed to slow down. It might hit a small boat or run into a cliff.

When you start to think about it, you see that we make use of lights a lot in our lives. If we want to have the same lifestyle as we do now, we need lights.

We can learn about light and how it gets to us. If we are smart with how we make and use power, we do not have to go without.
