I use a 50m string of white LED lights in the front garden, and it feels like I have to buy a new one every year (but maybe it's every other year) cos a section or number of sections have stopped working or are very weak.
Over the years they've not been particularly cheap, and in getting out the set from last year (which actually seems OK) I came across three of the broken ones.
The controllers are OK and the wiring all looks intact. The bulbs are not removable.
I guess it's more likely to be a wiring/connection problem than a broken bulb, but is it fair to assume it's the first bulb in the not working section which is bad, if not, how would I work out which one? Or is it more trouble than it's worth? ISTR these strings have been in the region of £30 - £40 but apart from the money, with my new green awareness, it seems awful wasteful to just chuck them away when it might not take much to fix them.
These all have one wire running the length of the string and each bulb has two wires in and two out. It's quite tricky following a wire to see the exact route as they are twisted together quite tightly. A failing section seems to be 5 or 6 bulbs, and either side of that work OK.
