I have an outdoor LED light chain, which consists of two parts.
This morning when I got up the second part of the LED chain had begun glowing very faintly (see image). The first part of the chain (which is nearest to the plug) is fine.
None of the bulbs are dead (as far as I can tell)
I checked the plug connecting the two parts and it looks dry. I measured the voltage across the plug and found 220 volts.
Does anyone know what is going on? And, more importantly, can this be repaired?

The lamps are wired from the mains to a transformer of sorts. There is no information on the transformer (or whatever the thing is). There is a label on the on the cabel itself that reads: Lamp spec. 10 buldbs (LED) per 3V, max 20mA. The plug that connects the two segments has two prongs. Everthing is connected to 220V mains. I measured 220V on the plug that connects the two segments.
Below is a picture of the plug the LED chain uses.
EDIT No. 2:
Below is a photo of the connector that connects the two strands of lights.
The bulbs are sadly integrated so I cannot remove them from their sockets.
EDIT No. 3:
I tried swapping out the strands and as expected the dim strand still didn't work. My old man then suggested I leave the defect strand in the boiler room overnight to 'dry out'. I did that and then it worked again. When I hung the strand again I could see water inside two of the bulbs. Many thanks to all that replied to my question!

With the help from Peter Duniho I tried reversing the strands and found that the problem persisted. My dad then suggested I put the defective strand in the boiler room to dry it out in case water had gotten in the circuit.
I left the strand for 30 hours and tried it again and it worked! When I hung the chain again I could see water in two of the bulbs.
Many thanks to the people that provided helpful suggestions!
