    I am new to trailers and Welding. But I’m mechanically inclined in very handy with most other things. Is there any thing wrong with running your trailer lights through the long support rails? Does it weaken it too much but the holes created if drills in the center? Rather than catching some type of conduit.

      Sure, running the wires through the beams is excellent. Yes, you need to think about where you drill holes — near beam ends is no problem because that’s not where the high loads and stresses are — but in the middle where the beams are highly loaded, probably not. Two issues with wires in the beams: 1) Servicing them (like if you damage a wire at the edge where it comes out of the hole), or if you want to add something like another set of lights. 2) Sealing the holes so that the beams don’t get moisture in to rust on the inside. If you can handle these, then yes, put the wires in the frame. It’s neat and clean and very protected.
