Thanks guys, won't be for a week or so yet as I only just ordered the Halo's on Thursday from the states, so they should be here early next week or possibly for this weekend, then just a case of making it fit the lens and finding some way to power everything. I think i'll wire the halo into the sidelight and work out some switch for the demon eye inside. As for sealing it back up, there is about a gallon of butyl used on these lights at the factory, but i'm gonna buy some more for sealing time.
I can let you into a little secret, though, this is a spare light with a broken face and mounts, thought I should play with it before using mine as I don't have an extra grand or so laying around for when I **** them up
