Navigation light wiring in place

I have routed two 5Amp wires around the cockpit, which link the port, starboard and stern navigation lights in parallel. The wires are hidden the under the side decks completely when running to the side lights, but the pop up into the open to reach the stern light. I have fitted a softwood moulding in each corner of the coaming, right at the stern, which covers them nicely there. I will paint the wood eventually and it will not notice to anyone.

Round the back of the coaming I have run the wires under the projecting hardwood edging, covered by a quadrant moulding which I had planed out at the back to form a run for them. I had to heat bend the moulding to get any chance of fitting it. The first go I inevitably bent it the wrong way and had to cut another length. The whole lot is now clamped on an epoxy bed, which I hope will hold it. About the trickiest clamping I have had to do. Nothing is parallel or thick enough t get a grip on. I wouldn't be surprised if the whole lot didn't just fall off when I release the clamps.
