Trailer kit with 2 stud mount tail lights; 2 stud mount amber clearance lights; license plate bracket; wire harness w/4-pole connector

by:

They look great installed. Only recommendation I can make is to include crimp connectors at least for the side marker lights and perhaps a small length of protective wire wrap.
All in all I’m very pleased.



by:

Excellent product. My old trailer lights were corroded and only worked intermittently. I began trying to clean & repair them, but it was a major PIA. I realized I could buy a brand new set for a reasonable price. They arrived today. This afternoon I installed them with no difficulty. They work great!

On-line ordering was clear and easy. Shipping was fast, etrailer kept me informed of my order status.



by:

The jack is decent. My only complaint would be that the wheel I purchased to go on to the jack does not pivot or turn when I push the trailer around.
I have to constantly kick the wheel in order to guide the trailer into position.



by:

The kit shipped and arrived quickly but the drivers side tail light was missing. Called and Lance took care of it and shipped the missing item the same day which was Saturday BTW. So, kudos for customer service, dont know where the item gathering fault lies. Can't rate the product as hurricane Debby won't let me install it yet.



by:

The order was promptly delivered and I have nothing bad to say about the quality of the product or the shipment. All of that is excellent. The only concern I had was that there was no instruction sheet included. I needed to get on the internet to find out about the wiring. Yeah you-tube!!



by:

Again you Guys have made life easy with your video and helpful tips!
Like your shipping packages as well. Compact with little waste of materials.
I used this product as a light system for my motorcycle carrier when I haul my TW200. With the bike on the carrier the vehicle taillights are blocked.
The TL29K light kit was what I used to solve this problem.



by:

Parts are missing... there is no way to connect the trailer lights to wire harness. The adapter is missing. Lights are useless to me this way.

Wow, that really bites! So sorry to hear that. I will have our customer service team reach out to you about this.



by:

Comes with everything for a great deal.



by:

Thanks Much, just got in from installing everything I ordered and it
all went on nicely. I rebuilt a 6' X 12' 1999 utility trailer
with treated lumber etc..........plus your parts, looks great. Thanks
again, going to do the same for another utility trailer I have, a
6' X 10, so, I'll be ordering from you later in the summer. Thanks
again



by:

The light kit was shipped promptly and nicely packaged. Everything looks to be made of very good components. I will be insalling this kit on a mobility scooter carrier and 90% of what I need was included in this kit.

Light kit from etrailer installation pi ctures.



by:

First off--Dealing with etrailer.com was a pleasure. The trailer light kit was just what we needed. Unfortunately our older trailer would not provide as good a ground as that required. The forward clearance lights worked fine but we had to individually ground the rear lights directly to the trailer frame next to the light mounts. Also, one of the rear lights, the one without the license plate light, had debris inside that precluded it lighting appropriately. After completely disassembling it we found wire shavings/cuttings that impeded a solid contact. Fortunately the co-owner of the trailer is an electrician and he had all the solutions. Alone I would have had to hire someone.

Lights continue to function appropriately after a year of exposure to Montana weather.



by:

The trailer kit I ordered arrived in a timely fashion and the items included are solid nice looking pieces.

I reviewed the video on installation and found the wiring and installation of the lights to be extremely simple. I rewired my entire trailer, replaced the tail lights and added the running lights (did not have these before I ordered the kit) in about two hours. Could have done it faster but I was in no rush.

I would definately recommend the company and products to anyone in need of replacing wiring and/or lights.

Product is still in place, still working beautifully. Did have to replace on of the tail lights but that was due to an issue with the tilt in the trailer and the light getting smashed on a rock -



by:

The kit parts were good quality and clearly marked. The order arrived quickly and the kit was a good value.



by:

Good looking lights. Installed easily.



by:

Product works as advertised except for wire clips. They keep falling off.



by:

Can't beat the prices and product selection. I was able to get bearings, races and seals to do two hubs for what I would have paid to do one locally. Although the bearing kits were made in China, they appeared to be a better quality bearing than the China bearings I removed from the hubs. No issues with packaging or shipping. Not only can one find parts here but, lots of good info and support as well.

The trailer I installed the parts on belongs to my 93 yr old neighbor. Needless to say, it is used very little. He and his son were planning on using it and wanted me to check it out before doing so. Thats when I discovered the need for new bearings and seals. He also wanted it road worthy for any of the neighbors that might need to borrow it. However, what time it has been used, it has done exceptionally well. Very smooth and quiet and although I had a bit of difficulty getting the pigtail to plug into the connection on the truck, all lights are working for the first time in many years. Thank you for checking in on us. Have a blessed day.



by:

I haven't installed the lights yet as I'm waiting to get the trailer sandblasted and painted. But, it's exactly what I needed and I'm sure they're gonna work out just fine. eTrailer has a great lighting selection to choose from including LED's.

I am very pleased with this product. Bought this kit to replace lights on a boat trailer from the 1980's.Install and wiring was easy to do with no problems. Lights worked great. Recommend this product.

I still like them just fine. Never an issue with either the hitch or the lights. Thanks

I want to thank the folks at e trailer for the good service. All the parts I ordered are of good quality, they all worked good and I will be using e trailer from now on! I also think that the email they sent with the instructions for each item was a great idea.

all is well and working fine. Your store is the best! could use LESS e-mails Thanks



by:

Looks nice, but no instructions whatsoever. The lights have copper holes in them, that are partially labeled, but some of the labels don't make any sense. And how can you stuff a twisted wire into a hole, it just doesn't work. How many engineers does is take to screw up a simple trailer light set? A pain in the butt, I wish I have never bought them. Will not by these sorts of things on line again, will go to local farm stores.

Each lamp will have two holes that are used for connection points. On the drivers side, one hole is for the brown wire, which is the running lamps. The other is for the left turn/brake lamp, which is the yellow wire. On the passenger side, one hole is for the brown running lamp wire, the other for the green right turn/brake lamp wire. To the wires, use a small flat blade screwdriver and push it in the small hole under the larger hole where the wire s. Push the stripped wire in until it stops, then remove the screwdriver. This locks the wire into place.

  • How do I ground my Standard 4-Way Y Harness on my Trailer

This wire provides the ground connection from your tow vehicle to the trailer once that is done all of the light ground themselves to the trailer through the metal studs used to connect them.

The part # RE18T is a set of 18 strips of conspicuity tape that is 18 inches long and 2 inches wide.

  • Is the 4-Way of the Standard Trailer Light Kit # TL29BK Compatible with OEM 4-Ways on Vehicles
    The 4-way of the Standard Trailer Light Kit # TL29BK that you referenced is the standard trailer wiring 4-way that is found on most trailers that would also be compatible with an OEM 4-way trailer wiring harness on a vehicle. They use a standard 1157 bulb. For a replacement you would want the # A1157B. The gauge of wire in this kit is 18.

  • Is There Difference Between Optronics Taillight Kits TL5RK and TL29BK
    The Optronics kits part # TL5RK and # TL29BK are both very similar. Only real difference is there is a slight housing design difference between the two main taillight assemblies with the # TL29BK having the more recent design. Both are great kits that will hold up really well, better than what came on your Harbor Freight trailer for sure.

  • Troubleshooting Running Lights Not Working
    There are many, many different reasons why your lights could not be working. In many cases a bad ground is to blame for this type of issue, but in order to determine the specific problem you will need to use a circuit tester such as # PTW2993 to test the connector on your vehicle after disconnecting it from your trailer. Check the wiring going into your harness from your taillights to see if those wires are carrying the correct signals, if not then the issue is with the vehicle wiring....

  • Ways to Install New 4-Pole Trailer Connector
    Four flat trailer wiring, also called 4-pole wiring, uses four wires and pins configured as shown in the linked photo of a trailer side 4-pole connector. The one pin that is different from the other three (on both trailer and vehicle side connectors) will be the ground pin and this usually has a WHITE wire that will ground to a clean bare metal spot the trailer frame with a ring terminal.

  • Locating a Lighting problem on a Boat Trailer with 4-Way Flat Wiring
    It sounds as if the trailer wiring is wired properly. You can splice into the brown tail light wire at any point and run it to the other side of the trailer. As long as the connector on your vehicle is wired and grounded properly the problem is with the trailer. A couple of things to look at would be the connection of the tail light mounting brackets to the trailer and the license plate bracket on the left side. If the mounting brackets are bolted to the trailer frame, remove them and...

  • Wiring a 2011 Victory Motorcycle and Trailer for Towing
    For simplicity, I would recommend wiring the motorcycle trailer as a vehicle trailer would be. A powered converter wiring kit, like part # C59496, would be connected to the motorcycle, which would provide a 4-pole trailer connector. The converter combines the brake lamp and the directional signal onto one circuit. The 4-pole connector utilizes four circuits, the white wire which is the ground, the green wire carries the right turn and brake light combined on one circuit, the yellow wire...

  • Troubleshooting Trailer Wiring Light Assembly that Doesn't Work On One Side of Trailer
    Try swapping the left side light assembly with the right to see if the problem stays on the same side of the trailer or moves to the other side. If the problem stays on the same side there is a problem with the ground or the wiring of the lighting. If the problem moves then you know the issue the light assembly. You may try running a jumper wire for the ground for the bad assembly back up to the main ground of the trailer.

  • Replacement Trailer Wiring Kit Recommendation for German Trailer to be Used w US Spec Kia Sorento
    Any time you can get away without using any type of adapter you are better off as that is one less thing to potentially give you issues in the future. That being said you'll want to make sure US style lighting is legal where you'll be traveling. If so the part # TL29BK would be an easy way to rewire your trailer to this style of lighting which would work well with your Sorento.

  • Troubleshooting Trailer Taillights that Stop Working When Brakes are Pressed
    Sounds like a weak ground circuit on your trailer wiring. This is pretty common and what you described matches this. Try improving the connection of the main ground wire of the trailer wiring harness. Make sure it is attached to a clean metal surface. Or you can run all of the trailer wires back to the main ground. This is actually the ideal solution. But you can also check the current grounds for the lights to make sure they are making a solid connection to a clean metal surface.

    What you would want to do is run the white wire on your trailer's wiring to the ground screw area of the trailer light to ensure that the ground will be sufficient for the light. Then you would just run the power wire to the single wire of the light and you would be good to go.

  • How Do Multiple Trailer Light Assemblies Normally Attach to Running Light Circuit.
    A lot of times people will use a butt connector to splice in the wiring of more than one light on trailer wiring. You'd put the end of the connector on the side that runs from the trailer connector and then run two wires into the other side to go to two separate lights. For connectors we have the part # DW05745-10. You can do this a few times to get a few extra circuits ran.

    Since none of the lights of the light kit # TL29BK work I'm guessing the problem is with the white ground wire.

If your trailer has an aluminum frame then you need to run a wire from the connector's white wire back to the mounting studs of each light in order to get a good ground. As far as wiring goes the wires are green for right turn and brake lights, yellow for left turn and brake lights and then...
