Changing Christmas light bulbs is a common task during the holidays. Here are the steps to follow:
1. Turn off the power to the light strands. This is essential to prevent electric shock.
2. Remove the bulb from the socket. Be gentle and don't force it. If it's stuck, try wiggling it back and forth.
3. Unscrew the old bulb and discard it. Be careful not to touch the metal parts of the bulb.
4. Insert a new bulb into the socket and turn it to lock it in place.
5. Test the bulb to ensure it works properly. If not, try another bulb.
