Hi everyone, Tim here from Chasing Pristine with another tip while home cleaning 

To replace broken Christmas tree lights, first turn off the power to the tree lights. Unplug the lights from the tree and inspect the string to locate the broken light bulb. Remove the broken bulb using a pair of needle-nose pliers or tweezers. Locate a replacement bulb in a compatible size, shape, and wattage. Insert the new bulb into the empty socket, being sure to face the correct direction. Plug the lights back into the tree and turn the power back on.

Test the lights to make sure they are working correctly. If the new bulb still does not light up, check the fuse associated with the tree lights. Unscrew the fuse from its holder and inspect it for damage. If it appears to be damaged, replace it with a new one of the same size and rating. Screw the new fuse back into place and then plug the lights back into the tree and turn on the power. Test the lights to make sure they are working correctly.

We hope this has helped
