Sounds like a plan. Worked a treat on the Indespension roller coaster trailer which sat lower and wider than my current Rapide trailer.
The original rubberised 12v bulb marker lights lasted a couple of seasons before they corroded internally. I subsequently fitted LED marker lights which were sealed units. I attached them to the mudguards and sealed them with sikaflex, then ran the wiring up to the hitch.
Because I use a light board, I added a connector near the tow hitch so it could detach prior to launching. You could of course add separate red and white LED marker lights, however it can work out expensive. On the positive side, they're less likely to get damaged as they're not directly on top of the mudguard if you go for the combined version.
