LED Combination Tail Light Kit for Trailers under 80" Wide - Submersible - Driver and Passenger - TLL9RK

Average Customer Rating:  4.8 out of 5 stars   (484 Customer Reviews)

Waterproof trailer light kit includes 2 combination tail lights that serve 7 functions on trailers under 80" wide. Stud mount with stainless steel hardware and included license plate bracket. 25' wiring harness with 4-pole connector.

by:

The TLL9RK Optronics LED Combination Tail Light Kit fit my old 4 foot by seven foot utility trailer perfectly. The lights are much brighter than the OEM incandescent units. I used crimp connectors instead of those supplied in the kit. I like the plugs that came with the new wiring harness, as they appear to seal much better when the trailer is connected to the tow vehicle. I only wish the kit included a blanking seal for each plug to help keep them clean and dry when not connected, as they spend most of their time unplugged and open to the weather.

Comments
A great product, the light kit is working well after a year with no problems.
Paul - 04/18/2023


by:

All went well except the ground wire was short on the trailer harness, had to splice a piece in.
Manufacture should consider making it another 12-18 inches longer.

Comments
Working great!
Charles - 11/15/2021

When my 7 year old utility trailer lost it's lights, I looked for a solution. The package came quickly and was easy to install. It was a good idea to include the wiring kit along with the Lights because I installed the lights first and discovered that the problem wasn't solved. I then rewired the entire harness and it all works well. I would recommend one change - instead of the wire nuts, add a waterproof heat sealing connection - I soldered my wire connections using a heat shrink wrap. Also - waterproof tap in connections for the side running lights would be helpful.



by:

This kit has all the parts needed to replace the old trailer lights. The hard part is removing the old, rusted bolts holding on the old lights.



by:

Arrived when scheduled. Installation was easy and they seem to be built well. Bright in sunlight. We'll see how they hold up. Could have used a few more wire clips-had to reuse some of the old ones.



by:

Always the best of quality and most complete package of trailer light replacements which is why I go to etrailer.com and am a repeat customer. These folks could write the book on how to give outstanding customer service and their people always friendly, professional and knowledgeable. This company is always a pleasure to do business with !!!!



by:

Adam personally looked at equipment I needed to answer my questions. I placed order on phone with him and it was packaged and processed and with shipping co. within hours. My installer said it was best choice so reaffirmed my selection. Gotta say the customer service and shipping guys were really moving and it was Memorial weekend. Can't imagine I'd use another company with such a great experience with this one. So far so good on the light kit, only submerged one day since installed but based off my installer and reviews I think I made the right choice. Will post updates if needed.



by:

Easy to install. There was plenty of length of wire to make the connections. Work great and looks great. Thank you.

Comments
Everything is working with no issues. Extremely happy with the lights.
Scott - 11/27/2022


by:

Love the lights. I would give them five stars all day long. The wiring harness is a bit chintzy. More like 2.5 stars. It feels like if the manufacturer spent another .02 on it the quality would be better. If you paint your trailer, you need to grind away the paint beneath the ground wire, otherwise they will not work.



by:

I bought this light set to replace the cheap, problematic light set on a trailer from Tractor Supply. Installation was straightforward, and the light have been working well.



by:

Wish I had changed to this technology many years old instead of constantly battling with the original bulb setup. I've had these on my trailer for about a year now and they've functioned flawlessly. For the cost and ease of installation, it's a no-brainer to go to LED lights.



by:

Very nice lights, thank you George at etrailer for contacting me and telling me I ordered incandescent lights instead of LEDs, that was greatly appreciated, because I wanted LEDs all along, I just ordered the wrong part.



by:

Fantastic. I would buy them again.



by:

I believe I must have received a returned product? It was missing hardware listed in the description. Luckily, I had some lock nuts that fit the mounting bolts of the lights and was able to successfully install the kit on my small trailer without having to make a trip to the hardware store or wait for etrailer to send out some replacements. I believe this was a “fluke” and if in need, I would certainly order a similar product again.



by:

Used these to replace old style on my 4x8 trailer.



by:

Patience and/or experience needed to replace trailer lights. fishing out the old wire running the full length of the trailer is tricky. You don’t want that connection between the old wire and the new wire to fail, or it will be very hard to get the new wire all the way through the frame. good weather, kneepads, or indoor workspace is important.



by:

The products are fine... the order processing and shipping were unbelievably fast... The one "downer" was that the lighting kit was put in the box without any additional packing/cushioning... the package split open and the contents of the kit were scattered among the tires... luckily, the lights/parts appear undamaged, as far as I can see... I have yet to install the kit and test it...



by:

The product is exactly what was listed on the website and the quality is great. I looked at Walmart, a local marina and a local part store for trailer lights. These lights I got from etrailer.com are better quality and a better price including shipping. It was delivered faster than expected. I was so pleased, I purchased more product from etrailer the next day.



by:

The product is as advertised, shipping was very quick. I haven't installed them, but I don't expect any issues.



by:

Exactly as described. I am not sure why manufacturers don't just include the trailer side and leave it at that. I have to cut the female connector off of the long wire harness, and splice in the male connector (who doesn't have a vehicle with a factory tow harness?), but aside from a few minutes of modification, it's perfectly fine.



by:

great replacement



by:

I haven't installed it yet, but all the parts look awesome and I can't wait to get it going.



by:

Rebuilt an old boat trailer. Had it powder coated and I needed a whole new light harness. This worked really well and looks good too.



by:

Excellent lights



by:

Lights are pretty good. The wiring harness, while adequate, didn’t provide very thick wires.

  • Can LED Trailer Light Kit part # TLL9RK be Backed Into Water on Boat Ramp
    The submersible LED trailer light kit part # TLL9RK is designed to be backed into water like when installed on a boat trailer. We still recommend unplugging the trailer wiring just because water and electricity don't like to mix well. We are aware that a lot of people leave them plugged in without any issue.

  • Can I Just Trim The Shroud On The New 4-Way To Fit My Application?
    Thank you for the pictures. Yes, you can simply trim the shroud on the wiring connector to make it fit. The perimeter was only to protect the pin connections from water, but is not absolutely necessary for use or functionality of the Submersible, Under 80" LED Trailer Light Kit with 25' Wiring Harness, # TLL9RK.

  • Should Hole Where Wires Come Out Of Submersible Trailer Light Be Sealed With Silicone
    There is a lot of confusion when folks say submersible or waterproof. The difference is that submersible lights will have a small hole that allows the water to drain out if the light has been submersed in water. Waterproof is a sealed light that will not allow water into the a light assembly. It is always a good idea to disconnect the lights before backing a trailer into the water just to make sure. You can use silicone to seal around the wires on the back of the light. Any extra...

  • Troubleshooting Dim LED Tail Lights On One Side Of Boat Trailer
    Many times the issue with a dim light on one side or the other is caused by a poor ground connection. You will want to inspect all of the ground locations as well as the ground wires coming from each light. Check for loose connections or pinched or bare wires. Since you said it is a submergible light, check to make sure the light housing has not been damaged and no water has managed to get inside the housing. If the lights on your trailer use a plug-in style pigtail harness look for damaged...

  • Should Trailer Running Lights Be Dim
    Typically the running light circuit will be noticeably dimmer than the brake/turn signal circuit, so what you described could be normal depending on how dim the lights are. Without seeing how dim the lights are it's hard to say for certain. If you installed the # TLL9RK that you referenced you can check out the review video I attached around the 1:30 mark to see the difference in the brightness of each circuit. I also attached a picture that shows the running light circuit on the right...

  • Left Side Trailer Lights Not Working With New LED Trailer Lights Installed
    The first thing that I would recommend checking are the ground connections for the trailer side connector and the lights. Poor ground connections are the most common culprit of trailer wiring issues. The lights will have either a ground wire or they will ground through the mounting hardware. Each of the ground connections should be secured to a clean, bare metal surface on the trailer frame or to the negative terminal of a trailer battery if you have one. If the ground connections check...

  • Will the Submersible, Under 80 Inch LED Trailer Light Kit Work with a 2004 Jeep Grand Cherokee
    This sounds like a ground problem on the trailer and not the vehicle. A weak or bad ground connection can cause all sorts of strange problems and what you are describing is actually common with any lights if there is a ground issue. The light kit # TLL9RK will work fine with your Jeep. Make sure that ground wires for the lights are attached to clean and corrosion free bare metal surfaces. Do the same with the main trailer connector ground. If you have a tilt trailer, folding tongue,...

  • Troubleshooting Trailer Taillights that Dont Blink When Running Lights are On
    What it sounds like is going on is that you have the wires from your trailer run backwards to the two illumination circuits of your trailer. This would explain why when the running lights are on the blinkers and stop lights aren't functioning. Since the harness of the lights has three wires you will need to make sure you are using all three of the wires. The running lights of your trailer should run to the wire on the lights that activates the lower intensity and the stop/turn circuit...

  • Trailer Light Recommendation for a 1984 Skeeter Wrangler Bass Boat

I attached a picture that has a standard trailer wiring diagram that should be helpful for you. The distance between the mounting studs is 2 inches.

  • Wiring Harness Included with # TLL9RK LED Submersible Light Kit
    There is indeed a wishbone harness included with the # TLL9RK Light Kit. The running light circuit is split into two separate circuits, one for each side of the trailer. I just got done installing this exact kit on my PWC trailer about a month ago. It was easy to install and I really like the brightness and reliability provided by LED lamps.

  • How do the Taillights in the Submersible Trailer Tail Light Kit Secure to the Trailer

Any of these grounds could be the culprit. Remember, paint and rust can insulate these ground connections so make sure the eye terminals have direct metal contact.

Or, you could hook your trailer up to a friends truck that you know has functional trailer lights and see if the trailer lights still react the same...
