Led flood light mounted on back of trailer

Thank you all for your information after thinking about it I did not want to permanently mount the floodlight just in the back but more or less to have them movable for lighting where is needed. Now I will run a wire with two separate rocker switches so that I can decide which light I would like on at which time

If you decide to add lights back there you should install a relay if the lights are not led. Non led flood lights could draw a large enough load and over tax your truck's electrical system and /or make wires hot. I am a believer in that the ele. system was not designed to handle much more load than stock and even a small draw could throw codes and create problems. Relay's are cheap and good assurance. I have 2 Walmart 4" back up lights installed off of my TV hitch and I wired in a toggle switch right next to them so I can also use them when hooking up at night. Works great! Put them on and don't worry about LEO issues! Safer to have them than not to and have decreased visibility.

Since the HID headlights came along for aftermarket installs, many states have changed their laws to make aftermarket headlights illegal. I drive an ambulance full time and dispise aftermarket HID headlights since 99% of them are installed in factory halogen headlight assemblies and blind the******out of you. Some states went overboard as did Louisiana. In order to combat the HID headlight issue, Lousiana changed the law to NO lighting that changes the factory original performance. Technically speaking, there are supposed to be no Non-factory lights installed unless they are DOT approved on any vehicle including trailers. The law specifically says trailers, semi trailers, to clarify that this is not just a big rig thing.

But like I posted earlier, our police just don't follow these vehicle laws. In fact, they protest these laws and refuse to enforce them. The reason being, there is no database available to law enforcement on the job that they can access to justify charging someone with. My wife is a cop and we argue constantly about why she refuses to pull over a 90's vehicle with blinding HID headlights. She said that these laws do not hold up in court and are tossed because they have no way of saying for sure that the lighting was not installed by the factory or dealer at the time of the traffic stop.
The other issue is conflict between state and federal law. Cops just don't want to go there. With the boom in natural gas production, drilling, fracking, etc, there are so many vehicles, trailers, etc, with added lighting and proving that those lights are not suppose to be there or that they are or aren't DOT approved is a waste.

Our inspection stations test factory vehicle lighting, wipers, windshield and horn. Lot's more on the list, but that's all that they actually inspect. Any tandem axle trailer has to be inspected for clearance and traffic lighting. As long as any additional lighting is not used on the road or used irresponsibly, our cops just don't touch it.

I bought these for my truck, but they would work just as good on a trailer.

LED Flood Light

I have 6 lights on the bottom of our 5'er. 2 are mounted near the front landing gear, 2 in front of the tires aimed out at 45*, and 2 on the rear. They are all LED flood lights which light up a pretty good area.
Wiring to the back was in the grey 1" conduit with a box at the halfway point for the middle lights. I also have them switched separately- front, middle- rear. I also have the ability to turn on the rear ones from inside the truck to give a little light when backing into a spot at truck stops, and such. What I did was buy the cheapest 14g 75 or 100' extension cord I could find.and used it inside the conduit. The LED's only have a 18 watt draw.

When I ran my wires to rear of the Toyhauler I ran them in a old garden hose. I measured how far it was to the rear of the trailer, laid out the hose on the ground, pushed the wires in the hose and then installed the hose along the trailer rails.

Although not bullet proof, this method has worked out well for a goodly amount of years.

X2. Add a nylon string to your wire loom so you can easily pull additional wires later if needed. Nylon will not rot.

Go ahead and mount it..nobody cares, These guys are talking about semi's and inspections etc, the DOT, LOL. There is nobody that is going to pull you over or even care if you mounted a light to the outside..heck toy haulers come with them from the factory.

As for your question I think I would run the wires under the carriage as it seems the easiest to do.

It's likely only obscured from that close up and above angle. From behind it's prolly clearly visible between the steps.

I doubt the driver leaves it there while in motion anyways.
