Gobi Stealth roof rack lights
 

I have a 2006 hummer h3 and just installed a Gobi Stealth roof rack ... and i want to add 4 lights to the front and 2 lights to the rear ... but I'm not sure how to wire them. The Gobi Stealth rack has some wiring (a black wire and a white wire) on each corner of the rack ... but I'm not sure how to install the lights ... can someone help? I'm comfortable with some of the wiring but I'm not sure how to use the wiring that is already there on the rack ... thanks.
