Thesis Statement
Light bulbs are a very important turning point in history because without them, we'd all be lost in the dark! Everywhere you go school, home, work, restaurants, and any other buildings, they're being used. Without them we would have to be using candles and lanterns, which you had to be very cautious of because they used fire and could cause damage to something or someone and also only lasted for a short period of time unlike light bulbs which didn't.
