For the guys who have lights on their roof racks, how did you get the wires for the lights into the jeep without it leaking?

Im debating making a small hole near the edge and then sealing it with silicone after the wires are run

 

That's how I did mine.. Drilled a small enough hole for the wires to feed through then used window sealing caulk to seal it up. And presto no leaks.
