all of the bushes and shrubs, but as soon as it rains or gets wet outside my GFCI breakers trip. I spent a lot of time last week putting lights up, and as soon as I finished rain moved in so I haven't been able to have all of the lights on any night yet. In the past I have spent time trying to isolate which strings are causing the problems, but my only conclusion was that a lot of them are causing it to trip. So now when it rains, a bunch of the lights just trip and don't work until it gets dry enough so when I reset the GFCI it doesn't just trip again within a few minutes. Kind of frustrating to spend that much time decorating only to have it not work reliably.

At least half of the light strings that I use are LED dome lights from Home Depot (bought most of them when they get marked down right before Christmas). Maybe they are just too cheap.

I have some Philips LED strings that have been very reliable and have lasted long enough now (some going 12 years strong) that the LEDs are getting noticeably dimmer. Thoses strings were more expensive, though.
