Gone are the days where if a bulb has burned out, your entire light set will be out. However sometimes a section of your Christmas lights may burn out. It is a very easy problem to solve.

If your Christmas Light Set doesn’t light, try these two simple steps:

  1. First, check each bulb to see that it is fully inserted into the socket. This is the most common cause for lights not lighting. A light set will stay lit with a bulb burnt out, as long as the bulb is still fully in the socket.

    Dura Lit, Stay Lit, Constant On and other lights where you can take the bulb out of the socket to stay lit, will need to have the bulb either fully in the socket or fully out of the socket. If it is not fully in or out, it will not light.

  2. Second, are the bulb wires making proper contact? Remove the bulb and adjust the wire if necessary. If neither of these solve the problem, then you may want to try one of our light keepers or another one of our light testing items.
