That's funny that these side markers had this issue, I have the IOM and have the same problem. I called Jonathan and told him the issue and yes I had to pay and send mine back but one of my rear led's went out. But they called and explained that they are gonna add extra silicon around the light. But that makes sense about the plug area being the entry point of water, seeing how when I held the light up side down to get water out noon came out. So they sent mine out today and I'll do like the other guy suggest and put silicon around the plug housing.
