Lights were a great invention that we still use today, they allow us to be able to see in the dark. The Telegraph was an important invention because it allowed you to get a message across to a receiving end. It was mostly used by the military to help communicate with our soldiers by using a secret code. New cars were also invented, these new cars were better put together because they were assembled by assembly lines and not by hand. Lastly the assembly line was invented and it was very important because it helps produce more materials and products than ever before. It was a new quick and efficient way to get the job done.
