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


After some light disassembly, these fit perfectly under the OEM lens covers of our vintage 1976 apache ramada. LED everything now!


Bright and works. One issue is right side passenger side blinks different and not as Bright as the left one.


Very satisfied. E-trailer had the right fit as I am replacing the tail lights. They were here in a timely fashion.




still working as they should thankyou


DURABLE BRIGHT QUALITY. I've taken my trailer and these lights all around North America (California, Yukon, Texas, Key West, Newfoundland) they have never let me down.



Bought these lights for my Karavan Double Sea-Doo trailer, excellent lights, better quality than the marina and better quality than the stock ones that came with it. Ver happy with them. All wiring was perfect and durable.


The lights came well packaged. All parts were included in a parts bag. I have some doubts as to the quality of the wiring connectors (3M 801). The white grounding wire is too short. I ran two additional lengths of ground wire directly to the lights and eliminated any trailer body induced grounding problems. The stainless bolts were 1/4" and I thought flat washers should have been included along with the stainless lock washers. I went to the local hardware store and purchased 4 each 1/4" flat washers to complete the installation. There was more than enough wire for my small PWC trailer. Installation was straight forward. The lights look very nice and are bright even in the daylight. Worth the purchase price.

Thanks for the follow up email. Everything is fine and I am satisfied.


Awesome direct replacement for my boat trailer. Much brighter than original that came on trailer



Still working as good as new

@Dennis We're glad to hear that the # TLL56RK taillight kit is still working well for you!


These are the best quality lights ever made and have used them for the last 20 years on several boats without fail because they really are waterproof. But the wiring harness and hardware is not but that's OK, just use your own stainless steel hardware and a more robust harness and your golden. FYI Over the years I've used every heat shrink wrap and other alleged waterproof products for connectors that have always failed. Hint, strip wires and twist the leads, fold them over and trim, then use electrical tape. If tightly wrapped with an ample amount of tape it will never fail and this includes below deck. fittings, ain't pretty but for me it's always been bullet proof.


Perfect size for small trailers. Arrived fast and in perfect condition.
Also purchased (and installed) two of the the Wesbar LED Trailer Clearance or Side Marker Light w/ Reflector - 1 Diode - Black Base - Amber Lens - 47-222012. Great products.


Great trailer lights.


Great product. I had to search a lot of different sites to find this size (roughly 6"x3.5") in a LED package because it had to fit my trailer bracket for the lights. As you can see in the picture the bracket protects two sides of the light so I needed the same size as the old ones. Thankfully had the kit and it shipped within 24 hours. It bolted right on and everything I needed was included in the kit. Very happy with the product and the order process and shipping time from eTrailer. I would recommend this product to anyone.


This is an excellent kit which seems to be a very good quality and is quite easy to install on the trailer. This will permit me back my trailer into the water without having to unplug before getting the lights wet. Also I would advise anyone doing a trailer wiring to keep in mind that if problems arise it most likely is due to a poor ground wire connection. The only problems I had with the lighting installation was due to ground wire not having sufficient contact.


The trailer these lights are installed on is used only during waterfowl hunting going into blackish water, swamp water, ice and snow and traveling through 3 states I hunt. I'm going into my second season and all the LEDs are lite.


Couldn’t be happier! Installation (removal of old bulb-type tail lights) and installed these in under 30 minutes. These lights are SO MUCH BRIGHTER!! Will definitely purchase again. Highly recommend these lights to whoever needs new trailer tail lights.



One year later and these lights have not disappointed. They’re working as well as when installed. Great product, price, shipping and an easy install. What’s not to like?


Submerged over 40 times still work great



Still working great


Very slight modification to make fit but was easy enough. Work well after one year of use. Worth the money.


Easy install. Everything I needed


Finally found led replacements that fits perfectly on my 1985 ez loader trailer!!! They were exactly what I was looking for. They are bright and look awesome!!!!!


Lights are great quality I love the LED, the only downside is I had to buy my own hardware an connectors because the one you guys send are not good for water, if the connectors were water resistant it would be great an better hardware.


LED lights on tail light kit is more than generous. It was easy to rewire into trailer. The only difficulty and perhaps my error is to wire it together with the old set for serious turning and stop signals. I drive mostly highways, curvy, etc and want my trailer to be noticed before a costly accident.
The light set came quickly and as depicted in advertisement. Thanks for a good purchasing choice.


Product worked perfectly. More important; I experienced the best Customer Service
in many years. It seems no Company cares about the customer. Jessica B.
was outstanding. From information, shipping to meet my needs to the follow-up
for delivery. I work for a Fortune 100 company for 32 years our customer service
had not matched this in over 15 years. Thanks for your product knowledge and
making a difference in customer satisfaction. Refreshing !! I will definetly be a returning customer and refer etrailer to my friends.


Great customer service, took the time to make sure of what I needed. Prompt delivery and follow-through with my trailer lights & wiring order!


Shipped on time. arrived without damage and worked perfectly for the use intended.

  • Upgrading Pop-Up Camper Taillights to LED
    Although they are a bit smaller than the lamps you are replacing, the Optronics # TTL56RK light kit would work great for you. The lamps would provide the same tail light, turn signal and brake light functions as the lamps you are replacing. The drivers side lamp will also provide illumination for the license plate. The only spot where you might have an issue would be in how the lamp attaches to the camper. The TLL56RK lamps are bolt mounted, with the head of the bolts fitting into slots...

  • How to Determine if Wiring Harness Included With TLL56RK Trailer Wiring Kit is Long Enough
    When I rewired my PWC trailer, I used a length of string to run from the trailer coupler back to each lamp then measured the string. I then added about 5 feet to that length for good measure to account for the length needed to reach the connector on the vehicle. The # TLL56RK kit includes a wishbone-style harness that is 25 feet in length, which I'd consider a great choice for a trailer up to 20 feet in length. If you click the provided link, you can see video showing the # TLL56RK kit...

These lights are virtually identical to the lights that came with the trailer so they will make a perfect replacement. They are 6-1/16" wide x 3-5/8" tall x 2-1/4" deep and come with a 25' wiring harness with a 4-way connection.

  • Is Conspicuity Tape Required for Use on Trailers Less Than 80 Inches Wide

  • Required DOT Lights for a Pop-Up Camper
    For light requirements you have to look at the total length and width of the trailer along with its gross capacity. The 1987 Coleman Sequoia is 14 feet, 11 inches long and 6 feet, 8 inches wide. That makes the trailer right at 80 inches wide, but less than 30 feet long and the gross weight will be less than 10,000 pounds. If you go with the under 80 regulations, which is likely how Coleman manufactured this trailer because that is how it is set up then the trailer will need to have: Back 2...

  • Where Is Trailer Measured To Determine What Lights Are Required
    Actually, the width of a trailer is determined by it's widest point. If the wheels are outside of the frame of the trailer then the width is measured for that trailer from outside of the fender to outside of the fender on the other side of the trailer. If the wheels are under the trailer frame then the measurement is taken at the frame width only. I have attached a helpful article that explains how to measure a trailer and the article has also got a complete breakdown of the lights...

  • What Does it Mean when a Trailer Light is Listed as Waterproof or Submersible
    When it comes to trailer taillights the terms waterproof and submersible are somewhat interchangeable. If a taillight is considered submersible that means that the internal circuits are waterproof and would be protected for if you were to back the trailer into water like when launching a boat. The part # TLL56RK that you referenced is listed as waterproof and submersible so it would work great on a boat trailer. Lights that aren't waterproof or submersible will still work just fine on...

    I have an explanation for you. Light kits like the LED Combination Tail Light Kit for Trailers under 80" Wide - Submersible part # TLL56RK and other submersible trailer light are actually a little confusing. They are not completely sealed, if fact it is just the opposite there are drain holes on the light that will allow for the water to drain out of the lights after they have been submerged.

  • Will Switching to LED Lights on Trailer Prevent Fuses From Blowing on 2013 Honda Pilot
    What I can tell you is that switching from incandescent lights to the LED Combination Tail Light Kit # TLL56RK for your ShoreLand'r trailer will 100 percent prevent you from continually blowing fuses. The reason is the minuscule power draw of these lights, with the stop and turn lights drawing about 0.27 amps and the marker lights about .06 amps. Your problem will definitely be solved in that regard. What we don't know for sure is everything the fuses on your 2013 Honda Pilot serve. I...

    There is a way for you to pretty easily find out the tail lights you need, although the SAE numbers just means it has been approved by the Society of Engineers and aren't a part number, and we don't have any way of knowing specific lights for any trailer. So you will simply need to measure your current tail lights and find the one that most closely matches your measurement, and also know if your lights are surface mounted or recessed mounted.
