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:

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:

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



by:

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

Exactly what I needed, plus very fast a rrival.

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.



by:

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.



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.

by:

It will fill my need in fixing lights in small boat trailer



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:

Good looking lights. Installed easily.



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.

The product was fine, etrailer however packed heavy items with this causing one light to be smashed. Fortunately, not a part I absolutely needed so not worth the effort to RMA this.

Unfortunately, Optronics doesnt offer instructions for the # TL29BK trailer taillight kit. However, if you click the link I provided to the trailer wiring help article, youll see a wiring diagram showing how the kit would be used to wire a trailer.



by:

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.



by:

TL29BK was easy to order, was delivered in a timely manner, and was a perfect match replacement for my 2010 Singer, Utility trailer. I was very much pleased and will certainly order from etrailer again if replacement parts are needed.

The Standard Trailer Light Kit with 25 Wire Harness is of very good quality and pricing and the order contained everything thing needed. I recommend this product.



by:

The connection (wire to taillight) for this trailer light kit is extremely flimsy and clearly not intended for external mounting. I ended up reordering submersible tail lights to get a more rugged connection. The wiring harness is fine and the tail lights work but the connection is flimsy.

It's very inexpensive but a few dollars more for a more rugged set of lights is probably a better buy.



by:

I bought springs, mounts and Tailight kit to fix up a rusty utility trailer. I cut, weld scraped and painted for the better part of a month in spare time. The springs and mounting instructions on e trailer are excellent. Only issue/shortcoming are the tail lights. Wire just pushes in and spring loaded strip holds them. I soldered and sealed the connection with silicone. So far that salt covered roads haven't hurt it in winter. The folks at etrailer are very helpful and prices are a good value.

  • Submersible Trailer Tail Light Kit TL29BK Does Not Need a Turn Signal Adapter
    You will not need an electronic turn signal adapter for the light kit. The wiring harness for your 1989 Nissan Pickup, part # HM43505, connects both the tail lights and turn signals. The wiring harness will then plug right into # TL29BK installed on your trailer and power the trailer lights properly.

  • Is Anything Else Needed to Install Trailer Light Kit # TL29BK
    The only other thing you might need to actually install light kit # TL29BK is a wiring kit such as # HM51020. But if you already have tools and connectors and the other items in the kit you will not need to add anything else. I have included a link to a video review of this light kit for you. One tip I can add is that to avoid ground problems down the road, either mount the license plate bracket by itself (and not sandwiched between the light and trailer frame) or put a ring terminal in...

  • Troubleshooting Trailer Taillights that All Go Out when Headlights and Brakes are Applied
    It sounds like you might have a bad ground connection. When the headlights are on, that is when there is the most power draw on the system. Stepping on the brakes would then add more and this is when a ground problem will usually show up. The taillights usually ground through the mounting bolts on trailers. Check for a bad ground, loose connection, and dirt and corrosion. Any of those can cause this problem. Also check the light bracket connections to the trailer frame as lights can ground...

  • Wiring Single Wire Clearance Lights on an Enclosed Trailer
    You will need to use a circuit tester, item # PTW2993 if needed, to test the wires exiting the trailer to figure out the wiring configuration with the trailer hooked up to the truck and the running lights on. You will probably find that you have taillight power on one of the green wires and no power on any of the other wires. In this case you would wire the two green wires to the power wire coming from the clearance light. You would then need to wire the two white wires coming from the...

  • Do All Lights Need to be Grounded on a Trailer with Incandescent Lights?
    With incandescent lights, you do not need to ground both lights. This is something that needs to be done with LED lights due to them drawing significantly less power. However, if you will upgrade to LED lights at some point, it never hurts to have everything already run to where it needs to be.

  • What Size Bulbs Are Used In The Optronics Trailer Light Kit, # TL29BK
    On the Optronics Trailer Light Kit, # TL29BK, the red taillights (ST8RB and ST9RB) use the clear bulb #1157 for the taillights and the clear bulb #168 for the side marker light. Our taillight bulb part number is, # A1157B. The side marker light part # 168 bulb is available in any auto parts store, we do not have that bulb available right now. The two marker lights (MC36AB) use the clear bulb # 194. Which is our part # A194B. The bulbs are included with the lights.

  • New Trailer Light Kit Not Working with 2 Vehicles
    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...

    The wiring I would go with, based on your dual axle trailer with 1 axle electric brakes, is the 7-way molded connector (10 feet long) # 50-67-005. The wire is insulated which protects it well from the elements. I recommend getting a junction box like # 38656 because it makes it easier to diagnose problems when using a junction box. If you need wiring from the junction box to the brake assemblies, you can use duplex wire # 10-2-1. Protecting your wiring from corrosion and moisture is very...

  • Which Trailer Light Kit is Best for a Jet Ski Trailer
    Trailer light kit # TL29BK does not include submersible lights, so water would be able to enter the light housings.

This is good practice, also, because it lets your wheel bearings...

    Since you have tested the vehicle side connector and they work correctly, you have eliminated the vehicle side as being the problem. So you will want to check the trailer wiring and the ground connections on the trailer. The Peterson M545 trailer wiring kit you have mentioned uses a wishbone harness like the Optronics Standard Trailer Light Kit # TL29BK that we sell.

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....

Both are great kits that will hold up really well, better than what came on your Harbor Freight trailer for sure.

It is odd that the issue only happens some of the time, so it could be this as well. If this ground looks good though, then your Tekonsha # 22119 has indeed gone bad and will need to be replaced. Especially since nothing else has been changed.
