chrisk,
Those oznium led's you put on your transom are awesome. Its funny to see somebody on here using them cus my buddy who does lighting and audio here in NC on Lake Norman installs those lights. Actually, any of the pictures or videos you see on ozniums websites are of boats he has done. I havent had him install them on my boat yet but it will be happenning after my stringer/floor job this winter. The only drawback to these lights is that they are aluminum and if your boat sits in the water for any length of time then they will start to oxidize.
Also, he installs them with stainless screws into the transom and uses 4200 sealant on the threads of the screws and around where the wiring goes through the hull. He even makes a killer lightring to go around speakers. Check him out at http://www.wavenoize.com/ If any of you decide to use him tell him that Will sent you. He sponsors my wakebaording! Great dude!
