help with waterproof blacklight

[dshaunt]

Anyone know how a could take a reg. 18in blacklight and make it waterproof, or at least be able to stand some rain..
We have two in the exit and entrance of our castle, I would really like to leave them there too.
Could a maybe just put clear plastic sheeting around them, since the lights don't get hot?

Try using a piece of roof gutter turned upside down!
place the light inside, of the gutter.
it' work's for us ,so far.
