Easy to install, quick shipment, I would use etrailer for anything related to my boat trailer.


I upgraded to LED lights on the trailer of my 18' Crestliner. The lights arrived on-time and in good condition. The follow-up by etrailer was outstanding.

The taillights are longer and not quite as high as the incandescent lights. They stick out approximately 2" further than the old lights, beyond the steel backing plate. I do not think it will be a problem. I like that I can now see my taillights in the mirrors. The two sets of holes in the steel backing plate did not line up with the new lights requiring me to drill an additional hole.

The taillights and clearance lights are extremely bright giving me much better visibility from behind. The Deka Heat Shrink Butt Connectors worked very well. The epoxy easily sealed the crimp marks and formed a watertight bond.

I haven't dunked the boat yet but I am very satisfied with the installation and do not anticipate any problems.


I was looking for a trailer taillight to match my existing lights. Perfect match! Easy to order, good price and quick delivery. It was easy to install in just a few minutes time. Thanks


This did not come with the mounting bolts as the picture shows.

I will have our customer service team reach out to you.

It's been over a year since I installed the lights on my boat trailer. They've been "dipped" in river and salt water several times and are still doing great. The old style incandescent bulb lights, sealed even, would have burned out long ago. Best lights I have ever had on my trailer. Thanks, etrailer


The LED trailer lights truly do make a world of difference. The only thing that I do have to say that is not a positive, is the fact that I had to drill out my mounting brackets on my trailer so these would properly fit. In other words the factory holes on my trailer did not match the aftermarket product. As far as the LED light visibility goes, again there truly is no comparison. The LED lights rock


Because I have an EZ Loader boat trailer I didn't notice that the light needs to have an oval hole on the back side to fit flush against the 3/4" nut that holds against the frame. Time will tell how well it works after using it in water. There is nothing wrong with the mfg. of the product. I've been on line now to the EZ loader site and it appears they have their trailer lights made for them. Now its mounted on end is up against the nut and the other end is not, so its on a little crooked. It works fine and I sure like the volume of light it puts out. Out here EZ Loader is a big supplier. Maybe you can talk to them?


Light fit my Featherlite trailer and looks great. Will definitely buy from etrailer again.


I received my trailer light, and when I looked at it closely it was cracked in two places.
there was a number on the box so I called it. the lady said if I could take a picture of the cracks and send it to them it would be helpful, so I did. they told me in an email how to return the light. in another email moments after that they said they pulled another one and are going to send it to be examined before being shipped, and if it's good will be shipped tomorrow (it was later in the day when this transpired). an email early the next morning stated that my trailer light was on its way. I think it's a great company to deal with and would recommend them. thank you etrailer


The tail lights for the boat trailer look great and work completely fine. The LED technology provides brighter lighting all around - making driving, turning, braking and backing safer in the daytime and at night!


Had looked in several places for clearance lights for my boat trailer. Etrailer had the ones I wanted plus the LED trailer lights I wanted. They also had the best price. I ordered them on a Friday and received shipping info on Saturday. The items came in with in 5 days. I am very satisfied and will use them again.


Outstanding product. Good quality, easy to install, and works great. LED lights are the only way to go for trailer lights. Bright light and withstands the elements well.


Love the LED Lights, no issues with bulbs burning out because it get wet. I still try to remember to unplug the trailer, but have forgotten a few times, and have had no issue.


Brightest tail light I’ve ever seen


The trailer light arrived promptly. The E trailer video regarding installation was great. I had no difficulty installing the light. It works great!

I will likely replace the passenger side light later this summer.


Products arrived on time and were high quality. Have ordered from here once before and have not been disappointed.


Very easy install. These are twice as bright as the old bulb lights. I changed all the lights on the trailer to LED's. I was always changing bulbs. Thanks etrailer


As usual I ordered & received a quality product in a timely time frame and it is exactly what I wanted and has been installed on my 2019 "Toy Hauler!" Much better than what came as "Standard equipment!"


Looks great, works great so far. Happy I replace those old bulb lights with modern LEDs. Much nicer and brilliant


Light is very bright and was a direct replacement to the original. Easy install and looking forward to many years of service!

Product working great one year later! Easy order and good quality.

Had to replace one of the brake lights on my boat trailer that had burnt out. 1 year on, still going strong. Good value, easy installation, works well.


I have tried various lights for a small boat trailer over the years.. these were the first that lasted more than a couple years. Highly recommend LED sealed lights.


I am tech not. I have a flip phone and a VERY basic fire. I have had great results with everything I've ordered from Etrailer.Highly recommend Etrailer to everyone.
