I am going to rip out my existing trailer lights and wiring and completely re-fit with Pipe Lights and a new harness. I would like to purchase a pre-made harness made of marine-grade tinned wire instead of the commonly available non-tinned harnesses. Where can I buy such a harness?

I realize I could build one myself but I'd rather just buy one pre-made and avoid the trouble.

I've never seen one and I've been watching.

Ancor does make a 16 ga. flat four cable with the right color
codes that would be a starting point. The wire is typical
Ancor marine grade stuff.

If I were to rewire my trailer, I'd have connect everything
up under the winch stand so it stays dry, and run wire
direct from there to each light. The only thing that stops
me is that my trailer is getting kinda rusty, and I think I'm
going to replace it in the next couple of years.

I hear you Chuck, I have searched the internet thoroughly (I think) and have come up with not one supplier who sells a pre-made harness from tinned marine wire. As you mentioned, I took note of the fact that Ancor manufactures 4-wire 16 ga. cables though.

I did find one ebay store (GenuinedealZ) which will custom fabricate harnesses using the Ancor wire. I have sent him the measurements for my trailer and proposed light setup and await his quote.

It has just hit me, if I am retrofitting with a system that keeps the lights out of the water, is there really any value added to going with a special tinned harness vice a cheap $10 off-the-shelf harness?

Also, to assure a long-term corrosion free ground on the new installation, I presume the lights should be grounded up by the tongue or another part of the trailer which doesn't get wet? Assuming this is the case, a basic 2-light harness is essentially two lengths of quadplex 16ga. wire.
Before running the two "legs" rearward through the trailer frame, I should "peel back" the ground wire from each leg
since these wires will be terminated in the front portion of the trailer vice back aft where the lights will be?

BTW, this harness will only be for two tail lights and no cleanrance lights (they are not required where I live).
