what do i do or what should i look for to fix it. and about 2 weeks ago i found some water in them but they just stop working to night. help me out plz.

 

I used to have underbody LEDs, and i had some condensation in my tubes as well. Never really hurt anything tho...

the one time mine stopped working is because the cheap in-line fuse assembly actually fell apart so they weren't getting any power. I would check the fuse if ur kit came with one.
