wet tail light 97

97 Jetta GL 2.0. Having problems with right side tail light bulb blowing. Change them almost one a week. Seems like the bulb housing is wet when I pull it apart to change the bulb. Outside housing has no visible cracks. Any guesses?

had the same thing. replaced the box and it still blew fuse after fuse.

found a small..pin hole size hole in tail light
