I had the same problem, my headlight blew so I replaced it and a week later it blew again. Then I noticed I had water in the headlight. Well, I wanted a quick fix and just took the headlight out, dumped the water and used a clear silicon glue to put around the outside of the headlight cover and where it attaches to the rest of the unit. Basically, where it was leaking. It worked, stopped leaking and it didn't cost me a thing. So, if you're lights aren't discolored that bad and you don't want to spend the money on new ones, just try some silicon.

One other quick solution is to just drill a drain hole in the bottom of the lens. Don't recommend it as you would be exposing the light to some elements but that would work too.
