C9 Christmas Lights Not Working

By the third week half of them did not work.

C9 christmas lights not working.

I have tried to buy replacement bulbs but i can not find them on an shelves where i bought them. Some christmas light testers work by having you slide each christmas light bulb through a hole. I checked the fuse as instructed but it still did not work after replacing the fuse. Second test the christmas light bulbs with an inexpensive tester available where holiday lights are sold and online usually changing a problem bulb or tightening it will fix the entire strand.

The christmas light tester will indicate which bulbs are bad and need to be replaced. I bought noma led large string lights for my house and i turn my christmas lights on the first of dec 1st. It combines a voltage detector bulb. The best option is to use either an electrician s multimeter or a tool specifically designed for repairing christmas lights such as the lightkeeper pro.

More than likely one of your mini light bulbs has popped out of it s socket modern mini lights are manufactured with a shunt wire that keeps the circuit intact if a bulb burns out. Start by checking for a blown fuse a common problem with a quick and easy fix. In other words if a bulb burns out the filament is blown the rest of the lights stay lit.
