Where every other bulb or set of connectable lights is out, this usually points to a connection issue with the typical cause that the lights have been connected together incorrectly.
Connectable lights are joined together using simple male and female connections. Pins from the male end are inserted into the relevant grooves on the female end. There are small notches/grooves to indicate how to connect together each set of lights or accessory.
If you are experiencing this problem, we recommend to disconnect each connection and reconnect, checking that the notches and grooves are in alignment at each connection, and that the screw cap is tight. In most cases this will resolve this particular problem.
Of course if you are stil experiencing issues having done this, and your connectable lights were purchased from Festive Lights, please do contact us and we’ll be happy to assist.
