Turn off the light switch in the bathroom and wait for the bulbs to cool completely.
Twist the bulb to the left to unscrew and remove from the socket and metal collar. If the bulb is broken or is loose from the threaded plug, continue troubleshooting.
Turn off the electricity to the bathroom at the circuit breaker.
Grip the bulb while wearing work gloves and twist off. If the plug is still screwed into the socket and collar, grip the plug along the metal edge with needle nose pliers and rotate it counterclockwise to remove. Do not use your bare hands.
