hid ballast mounting location

[philiobuster]

Hi all, first post here. Did a bunch of research on the site, which helped me get my hids with depos installed successfully (and as economically as possible). Thanks to all the previous posters. Now that I've got everything wired and working, I'm looking for the ideal place to mount the hid ballasts. I'd like to protect the ballasts from the elements, especially rain. Anyone have any good ideas?

Also, the aftermarket ballasts i purchased did not come with rubber caps to prevent condensation in the headlamp. Anyone know where i can purchase these? I'm using duct tape and sealing it the ends with zip ties as a temporary solution.
