How to Fix Christmas Lights

You just finished decorating your Christmas tree with ornaments and Christmas lights. Suddenly, you notice a few bulbs are burned out. No problem; you have several spare bulbs in a drawer that you saved just for this moment. Wait, these are old bulbs from several years ago and the base of the bulbs won't fit into the socket of the burned out lights. What now?

Remove the burned-out Christmas light bulb from its socket. Do this by carefully applying upward pressure on the plastic base just below the glass bulb. It helps to have fingernails when doing this. Try not to pull on the glass bulb.

Once the old bulb has been removed, compare its base with that of the replacement bulb. If it matches, then you should have no problem easily just inserting the new bulb into the socket. If the bases do not match, then you will need to remove both bulbs from their sockets and swap them.

You will probably need to straighten the wires so that they will fit into the holes of the socket.

To remove a Christmas light from its socket, find the two copper wires at the base of the bulb. Push both wires downward so that if the tip of the bulb is pointing at the ceiling, then the wires will point towards the floor. Firmly pull upward on the glass bulb and it should separate from the base. Do the same thing with the replacement bulb.

With both copper wires from the new bulb pointing straight down, insert the new bulb into the old bulb's socket and try to align the copper wires with the two holes at the bottom of the base. Once the wires have been inserted, press the bulb completely down into the base. Push both wires upward so that they follow the groove on each side of the bulb base. Now they should be facing the same direction as the tip of the glass bulb. Insert this new arrangement into the empty light socket and the bulb should illuminate!

Tips & Warnings

• Be careful when working with electricity! If possible, wrap a small piece of masking tape around the base of the burned-out bulbs to mark them and them perform the bulb replacement with the Christmas lights unplugged.
