Ok- so I have had 2 sets of clear rope lights that I have used on and off stage, other various events and around my house. There have been times when they are on for a few hours to times when they have been on 24/7. These lights are at least 5 or 6 years old. They had been stored for several months. After placeing them I plugged them in only to find about half of each string worked, but there was no pattern as to which individual sections worked and did not. I contined to use the lights as decoration running 24/7. Recently, I noticed the 2 main leads had turned a green color. In some areas limited to approx. 2", the light bubs, the main and secondary power wires- the entire rope was completely saturated with this green color. Mainly the sections that did not work but not isolated in those areas. One of the 2 power connecters was saturated. This green color appeared after they were brought out of storage and again into use. After noticing the extent to which this occured, I discontinued use. I just got around to removing these rope lights and decided to cut a section that was saturated with this green color. To my surprise, the green was fluid. It was sticky- thick, but fluid and very green. Also, the power connector had began to leak this fluid, though I had previously missed it. What was this? What caused this? Has anyone else had this problem? Thanks.
