回答“Half of the string of LED Christmas lights doesn't light up.”I have been struggling with these stupid LED lights for years. I get the failed half string plus squirrels chewing lights right out of the string. This year I repaired 5 or 6 strings by taking the good half and cutting off the bad half then attaching the male or female plug at each end with Marette connectors. I know, I know. Crappy unsafe fix but they are crappy lights. I have both types. Solid connected lights that can't be removed and the ones with two wires that can be replaced. The biggest problem has been the solid ones because they must look like nuts to the squirrels. One day after I fixed them 4 strings were chewed in 5 places. Took the Marettes to the strings. One light has to come out because they chew so close to the base. In desperation I have a theory, that is wrong, that if I leave the lights on they won't chew them. They do chew them even when they are on but I leave them on for the remote possibility I am right. I have now gone 5 days and all strings are working. I notice they don't eat...
回答“Half of the string of LED Christmas lights doesn't light up.”Anyone from Canada on this discussion? I have the front half of two LED strings out but up here we have no fuses or fusible links and the LEDs are not replaceable and the plug is polarized. Looks like the trash for these lights. What the heck is the point of having LEDs that save electricity and are supposed to last 250,000 hours if you can't even get them through 1000 hours? And they are not cheap. They are 2 or 3 times the old incandescants which were a pain when a bulb went out but at least they could be fixed if you took the time. Any ideas before I head out to Canadian Tire? Odd thing is there are two wires at front end then it goes to three on first bulb so those wires must be good. There's .008 A on them and of course 0 on the third that comes out of the first bulb. And 120 V at the plug at the end. I had a third string with half out but jiggling the wires got the bad half back.
