Well that is what I thought when the guy mentioned it to me. But I figured that if I needed to replace the housing anyway, why not give it a try and it seems to be working for me after almost a year.

I used a 1/16 bit and drill three or four holes along the bottom. You gotta make sure you don't drill near the lense otherwise it might break.

I don't have any moisture at all in the lenses anymore so, it's not like I'm getting my connector wet or anything. Since that I have had no water problems in the trunk either.
