Cheers folks
The light off them is bloody brilliant, they are driving lamps and they are positioned so the beam is just above the spots from high beam and its like daylight with them all on.
The wiring is all inside the cross rail and then into the side rail, I had to drill the roof under the foot of the side rail and then run the feed down the a pillar inside, all grometted and as its under the rubber mount for the roof bars very little chance of any water ingress. I really wanted this to be as clean an installation as possible, would never of done it if there was a chance of seeing the wiring anywhere, all that is visible, is about 2 inches on each lamp where it goes into the gromett on the under side of the cross rail.
I'll try and get some pictures of how they look in the dark soon
