Taillight leaks

[Sallad420]

Hi all, I noticed the other day my taillight (drivers side) had about 0.5 inch of water in the Reverse Light section of the light. I took it off and dumped the water out, but how would it have gotten in there. Obviously there is a leak, but I looked it over and there are no visable cracks, or openings anywhere.

So any clues on how to fix this? I could just drill a small hole in the bottom of the light to keep it drained, but I would rather find the leak.

Is this a common problem?

Thanks.

Usually, ( not always ) it is from the seams.
Run a thin bead of scillicon around the seam.
Have some rags handy for clean up.

My truck is doing this, and the silicon doesn't seem to help.
