C9 christmas lights not working.

You re not crazy those lights did work last year. There are several ways to repair your lights depending on the problem and how hands on you re willing to get.

In other words if a bulb burns out the filament is blown the rest of the lights stay lit. Start by checking for a blown fuse a common problem with a quick and easy fix.

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.
