How to wire light bar

[pdxrealtor]

Thanks, but I have the bar stripped already. It's not 100% hollow in there.

After looking at it more I can either drill through the first outside layer and run the wire down the first hollow core, or I can drill through the first and second layer and run the wire down the center top core.

The second would give me better access for running the wire, but at the same time I can just use a wire puller to grab the wire if I use the first method.

Then there is the exit point.. not sure yet where the best exit point would be?
