New input case for you: I flipped up the light switch to illuminate my federal, and instantly watched as the lightbulb went on and then immediately shut off. That let me know that the lightbulb was blown, and that it needed to be changed. First I went to the linen closet, and removed a brand-new lightbulb from the box. I went back to the bedroom and turned the light switch back into the off position. I then placed a stool underneath the lightbulb, and climbed on top carefully, with the new label in one hand. Once I was in position to remove the old lightbulb, I placed the new lightbulb on the top of the stool in a safe place, then placed my hand on the blown lightbulb to inshore it was not too hot to handle. Once I realized the lightbulb was cool to the touch, I began to screw the light above in a clockwise motion in order to remove the lightbulb from the light fixture. Once the lightbulb was release, I bent over and placed the old bowl on the top of the stool, then picked up the brand-new lightbulb. I then stood back up so that I could reach the light fixture, and placed the middle portion of the lightbulb into the light fixture. I began to screw the lightbulb in a counterclockwise motion, ensuring that the metal thread of the lightbulb was aligned correctly with the light fixture to inshore that the lightbulb would be evenly inserted into the opening. Once the lightbulb was completely emplaced, then I stepped down off of the stool and back onto the floor, removing the old light bold and the stool from the middle of the room. Then, to check to make sure that the new ball had been inserted correctly, I flicked the light switch from the off position to the on position and looked up to see that the new label of have been illuminated. 
Question: Why did the light go out?
Output:
Because it blew.
