Hello this is my first post

I would like to install led flood lights to the rear of my trailer with a separate rocker switch located near the battery in front of the trailer. My thought is that I will be able to flood the area I'm trying to back into.
I would like to know thoughts on the best way to install something like this... Should I run the wire under the carriage or snaking it between the roof and ceiling?

Funny how off topic everyone gets..
OP wants to install the switch and lights on the trailer. Not the switch on the truck and lights on the trailer. Or both lights & switch on the truck.

Do Trailers have to get annual DOT inspections? Pretty sure not.

And besides that having both the switch and light on the trailer make it pretty hard to activate the light while driving.

If you are worried about it, but some lights with covers, then leave the covers on until you need them. Pretty hard for DOT to argue with covers, and it will protect your lights.

Personally, I would install the lights under the trailer. It would give you a better perception of the terrain, by creating shadows which would show the dips/highs of the terrain. If you lights are on top of the trailer, you won't see the dips/highs as well..

PA REQUIRES ANY MOTORIZED AND NON MOTORIZED RV (IE TRAILERS EXCEEDING 3K lbs GVW) to have an ANNUAL SAFETY INSPECTION. I suspect there ARE other states that have same or similar requirements..

When getting my trailer inspected, ALL LIGHTS which serve as markers, tail/stop/turn AND BACKUP FUNCTIONS ARE TESTED.

Failure of any these lights to work FROM THE CAB will result in a failed inspection.

Placing a switch on the trailer to operate backup lights (or lights you placed on the back FOR BACKUP PURPOSES) WILL RESULT IN A FAILED PA INSPECTION, PERIOD.

PA mechanics TEST all the marker, tail/stop/turn and backup lights to ensure they operate FROM THE CAB.

Scare lights ARE NOT THERE FOR BACKUP PURPOSES and as such are not part of PA inspection routine (they have never failed my inspection for my side door lights since that is not typically used while traveling)..
