I have spyder ccfl halos head lights, and led tails for almost two years now with the HID blasts that came with the head lights, no issues with either, except bounce on the headlights that has been fixed. I did nothing special to them and i have no water in them. the tails are a much better fit but there still is a gap at the bottom, its only noticeable if you get your eyes even or below the tail light lol.
You just have to know what you are getting into
