How do you change a light bulb in a ceiling fixture?
assistant
To replace a light bulb in a ceiling fixture, start by unscrewing the mounting screws from the ceiling. Then, remove the old light bulb and set it aside. Next, screw the new light bulb into the socket and tighten the mounting screws to secure it in place. Finally, turn on the power and test the light bulb to make sure it is working properly.
