1. Light bulbs
This invention allows us to see and work in the dark. Long ago before lights are invented, we cannot do much during night time, even if you light up a candle, it won't last long and they may catch other things on fire. Light bulbs can be used for a long time, and they're a lot safer and there's a lot more we can do in our lives in nighttime nowadays. Even though yes LEDs are taking over, but before LED is invented, light bulbs are certainly important.

3. Radio
Radio gives us a simple and fast way to send messages and spread information to far locations. This is very useful especially back then, where people can spread information during wars or other emergency situations. We can contact others faster.
