How do I change a light bulb?

Response:
In order to change a light bulb, you will first need to find a replacement. Make sure to disable power to the bulb before removing or installing it. You can find the size, type, and wattage written on the bulb you are trying to replace. If the information isn't on the bulb, you can take the bulb with you to the store to help you match it to a replacement. Remove the dead bulb and install the replacement. Then restore power to the bulb to test it.
