Water in headlight?

[RussR]

Hey Guys & Gals,
Sorry if this is the wrong spot, but i'm having a few issues with my recently purchased AU2. Basically i'm getting water in the passenger side headlight, and it is shorting and blowing the bulb. Is it a sealed unit? is there a replaceable rubber or something? to inspect it according to to the book i have to take the grille & bumper off, and i'd prefer to get a rough idea on what to do before i spend half a day doing that.

Thanks for all the replies in advance
