how to install trailer lights

[@williamblan6265]

A good hack for running the wires down the tongue. Just run a tape measure down the tube and out the other side then lock it, go to the other and and tape your wires to the end of it, then go back, unlock it and pull the wires back through. Works every time and everyone has a tape measure.

[@neilkincade4019]

How did you connect your side lights?

[@massis32210]

You would just tapping into the wire that controls the running lights so when you turn your running lights on at night it would just illuminate the side markers

[@davidtravis1367]

I was woundering if u could use the yellow and green for the driver side and put the taillights on just the one wire

[@massis32210]

To be honest at all really depends on the kit that you get most are fairly simple but always refer to the instructions or wiring diagram to get with your kit

azhaynes two wire rims side marker lights you would tap into the wire that feeds the turn signals and the running lights that way when you make a turn the lights will Flash and when you have running lights on it would activate the side marker lights. Hope that helps thanks for watching

[@gordonfelthauser4708]

Where did you put the ground?

[@massis32210]

The white wire which is ground that comes off the harness normally what I'll do is drill a very tiny hole and use a self-tapping screw with an eyelid on the wire and ground it right straight to the trailer.

[@joewoodchuck3824]

If a tow vehicle has seperate turn signals, i put the extra lights on to accomodate. I very much dislike using the electronic adaptors because its just another thing to fail. The seperate turn signal system is also a superior design, so why not use it? I also always go for interior trailer connectors. I also keep the trailer end in an enclosed box when not in use. Theres nothing like clean connectors to maintain reliablity.

[@massis32210]

I agree as far as on the electrical connectors they're honestly nothing but junk made for someone too lazy to find an alternative way of hooking up the wires thanks for watching

[@michaelphipps4313]

Very helpful 👍👍👍

[@rustykeller8264]

Somebody probably already mentioned this, but the only error I saw, was you installed the license plate holder backwards. The clear plastic window on the left tail light is to illuminate your license plate at night. The plate holder, needs to be installed in reverse (to how you did it), so the license plate is under the clear plastic window. Other than that, Good Job.

[@marcos22571]

What's the lenght of the wire on those lights?

The wiring harness should be 16 ft if I remember right if you have a trailer longer the 16ft you can buy four strand trailer wiring to extend the wiring harness

[@daveoverbey2032]

You don't like the wire nuts on account they are not water tight. But a trick I learned years ago while wiring outside stuff with wire nuts is to squirt just a dab of 100% silicone into the nut & then put my wires together twisting them into the nut snug n tight & presto they are now water tight.

[@massis32210]

Dave Overbey that is a great idea, I will try that. Thank you for sharing your idea. thanks for watching.

yeah, if your a jack leg mechanic lol. shrink wrap is full proof and looks professional too

coat it with liquid electrical tape that stuff completely seals when its dry

The yellow lights you'll tap in into the wire that runs the running lights. They give you these little blue push connectors don't use them their garbage.

massis32210 Thanks for the response. But I can't figure out what they clip onto. I'm going to use them for my ground but they don't seem to fit any of the other hardware.

[@massis32210]

Nick Lozowy I didn't explain the inside of the properly, there are two channels inside of it. One runs all the way through, and one just goes half way through. you slip the wire that you want to tap power from in the long grove and the other wire goes in the short slot. in the middle of it is a metal blade like thing that you would squeeze down with a set of pliers and then it would Pierce both wires just insulation enough to send power from one wire to the other one without having to actually physically cut both of them. I have used them in the past but I personally don't like them I've had them cut wires completely in half and if you do use one I would recommend putting the heat shrink on before using it a large enough one that you could heat shrink the whole thing to keep it waterproof

Those leaf springs could haul a space shuttle... If you had access to a welder, maybe you could relocate those tail light brackets. I don't know why anyone would build a trailer with lights on the corner like that. It's begging them to be smashed to pieces.

[@massis32210]

With the tail lights at all depends if they're going to be way too low or sometimes you just want to abide by the law thanks for watching

[@oldtimer7146]

Don't forget that the metal bolts on the back of the lights have to make good electrical contact with the metal on the trailer. That completes the electrical connection via a ground. So, if the trailer is rusted at the point where those metal bolts connect to the trailer, you may want to remove the rust first. Also, if the holes that the bolts go through are too big, there may be no electrical connection. That was the case on my trailer, and I ended up fashioning an aluminum bracket with smaller holes to the back of the lights, and then grounded the bracket itself to the trailer by drilling a smaller hole through both the bracket and the trailer and fastening with a third bolt.

[@massis32210]
