Occasionally a section of lights may go out in your Artificial Christmas Tree. This is typically the result of a bulb that has become loose from the socket. When this is the case, a standard light tester designed to check for current is all that is needed to locate the bulb that needs replacing. Many tree owners find themselves confused as to how they should operate their light tester, and are unsure as to exactly what they need to look for. Below is a basic guideline to help you test for faulty bulbs.
Light testers are included with every prelit incandescent artificial Christmas tree sold at Christmas Lights, Etc. The light tester consists of a red and green LED light, and a green pointed tip.
If results from the light tester failed to result in red or green lights, there may be no current in the string or multiple bulbs are out, and additional steps must be taken.
"One Light Goes Out, Rest Stay Lit" is a technology that uses an internal shunt within the bulb to continue the flow of electricity throughout a light string, even if a bulb has burned out. It is important to understand that if the shunt is broken when a bulb breaks, or if it is dislodged due to a loose bulb, the flow of electricity will stop. Additionally, each mini light has two small copper wires that come out of the base of the bulb, and fold upwards on each side. When the socket is in place and the bulb is secure, this allows for the current to continue to flow. Sometimes the copper wire may be broken or out of position, and replacing the bulb or moving the copper wires into place should remedy the problem.
We advise everyone to test for faulty bulbs before storing their artificial Christmas tree for the year. Proper storage of Christmas trees also helps to prevent wear and tear on mini lights.
