    How can I tell what Christmas light socket or bulb isn't working?

    One my strand of Xmas lights for outdoors, one section doesn't light up. How can I tell where the problem is?

    check from the first bulb that wont light up in the chain, that is usually the defective one that breaks the circuit. if that fails look for a master bulb; a master bulb will look slightly different from the others may have white at the tip or another color. Hope that helps Paul.....jimmy

      I replaced each light in the section that won't light up (fingers hurt) and no dice.  I think a socket must have an issue.

    You can go get a light tester at Target or Walmart. It looks like a black stick with a little screen on it. What you do is you touch it to a bulb that doesn't light up and it will tell you if it has a charge or not.

      I think that's what I need to do.  Somewhere in that section there's a faulty wire or light breaking the circuit.  I'll find it!

    I would just test the ones that don't light up with a bulb that works, but you already did that, so it could be the socket.  So you don't have a gap in you strand of lights, just overlap a working section over the ones not working and save yourself a headache and sore fingers. Don't know if you are by a Home Depot store, but the one by me will exchange old lights for new ones that are energy efficient. Happy Holidays!

    Just went through this with a star with lights, one by one testing each unlit bulb in the section; several bulbs were bad and looked dark; then had to find 3 replacement bulbs...not easy because not all are the same size. If was fixed in end but not sure I would do that on a long strand. I love the idea from Lupine. I didn't realize some stores are willing to exchange for energy-efficient ones. Another idea is to overlap on top of the old bad lights. You think by now they would have to discover something easy to fix lights, maybe someday.

    Happy lighting!

      Thanks, easylearningweb, yes, overlapping more than one strand is a good many more lights!
