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.


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.
Rob - 06/21/2022


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.
Tom S - 10/27/2017


it is just what i wanted, tail lights that fit my 23 year old trailex trailer. somebody decided they needed my tag that had been on the trailer for 23 years. they tore it off. rusty bolts and all that, plus lights that you can see in daylight! great stuff. thank you. richard


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.


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.


Excellent customer service and excellent product. I had a problem with a cracked lens over the license plate. Dawn from customer service was on it and I couldn't have been happier with her commitment to fixing the issue.


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.


3rd time that I have ordered from etrailer. Each time the product was advertised. These were tail lights for my boat trailer. They had to fit in a protective bracket. Fit perfectly. Warning-don't try to break ice with your trailer or you may be buying new lights.


These particular tail lights are pretty hard to find,for the size I needed,so I found them here as a kit,I actually didn't need nothing but the 2 bulbs.....ordered them,paid $xx extra for UPS shipping,get a email from one of their representatives stating that he upgraded my shipping at no additional cost,after I done paid for premium shipping.....guess what,it still cost me $xx,and their wasn't any upgraded shipping....all in all,great quick responses on emials,emails, my $xx shipping was here in 3days....

These lights do come individually with part # STL56RB
LED Trailer Tail Light - 6 Function - Submersible - 18 Diodes - Rectangle - Red Lens - Passenger
for the passenger side and part # STL57RB
LED Combination Trailer Tail Light - 7 Function - Submersible - 23 Diodes - Red Lens - Driver Side
for the drivers side.
-- Etrailer Expert Heather A - 03/07/2022


Lights have been one of the best upgrades I have made to the small boat trailer. Lights are very bright and noticeable when compared to the old incandescent 1157s.


Lights worked great and are much better then the original lights I had on my utility trailer. I did not use the wiring harness because my original one was an 8 wire


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



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.


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


Last time I saw the trailer they were still working. Trailer belongs to a friend.


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 led trailer light set. I just indtalled it today!


Worked great! Easy to install & price was right! Thanks, we’ll reorder if we need one for any of our other trailers.


This was exactly what I was looking for - fast delivery - well-packaged - customer service was helpful, friendly and professional - very happy with the item received


Lights fit my 99’ Shorlandr trailer perfectly. Easy transaction. Thank you.


Love these lights! Replaced a broken light with these. East to install and super bright. Perfect fit with clear instructions for mounting. Great value!


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.


These lights are great!! I replaced the old filament style lights on my trailer with the LED's because I am on rough dirt roads almost exclusively and got tired of replacing bulbs. These lights installed quickly and easily, they are highly visible, and work like a charm. I am looking forward to less maintenance on my trailer lights, that's for sure!

After a year of rough use the lights are working perfectly!
Arin W - 11/06/2017


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.


Easy install, bright LED's. Shipment via Zap they arrived in a matter of days.

  • 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...

  • 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...

  • 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...
