Mounting lights on roof.

Everyone does the bull bar or light bar with lights up front. So Im going to try to mount some lights on a cargo basket on my roof. See how it looks. Short of drilling a hole in my roof to run the wires, what would be the best way to run the wires? I was kind of thinking running the wire back into the top of my rear window some how. Any ideas? And the people that already did this, how did you run the wires?

 

run them through the gutters... there should be holes that you could squeeze wires into

 

A little late, but this article (http://www.oramagazine.com/pastIssues/0503-issue/050301t-maya-hunter.html) might help... I'd like to mount lights in a cargo basket just like this...
