how to change bulb in christmas lights

The first step is to find the bulb that needs to be replaced. Look for the bulb that is burnt out or is not working properly. Next, carefully remove the bulb from the string of lights. Be sure to grip the bulb firmly so that it does not slip out of your hand and break. Once the bulb is removed, check the base of the bulb to see if it is compatible with the type of lights you are using. If it is, then simply replace the bulb and test the lights to make sure they work properly.
