Features to know about

Brighter, Longer-Lasting Illumination: 18-Diode LED Design

This low-profile trailer light uses 18 red LEDs to deliver bright, efficient performance while drawing minimal power. At 12.8 volts it only pulls 0.252 amps on stop or turn and 0.135 amps for tail, so it stays cool and efficient without stressing your wiring. LEDs last up to 50 times longer than old-style bulbs and don’t have fragile filaments to burn out, meaning no more swapping bulbs after every season.

Built for the Water: Fully Sealed and Submersible Construction

If your trailer sees water, this light is ready for it. The circuit board is completely sealed inside a durable plastic housing with an acrylic lens, keeping out moisture that ruins conventional lights. Whether you’re launching at the ramp or driving through rain, the sealed waterproof design prevents corrosion and keeps the LEDs shining bright trip after trip.

All-in-One Lighting Solution: 7 Functions in One Unit

One light covers it all—stop, tail, turn, side marker, side reflex reflector, rear reflex reflector, and license plate light. That’s seven functions handled by a single compact rectangle measuring 8" long x 2-7/8" tall x 2-13/16" deep. It cleans up your setup by replacing multiple lights with one dependable unit that meets DOT requirements for safe, visible operation on the road.

Quick Mounting and Simple Wiring: Surface-Mount with 3-Wire Pigtail

Mounting is straightforward thanks to the surface-mount design and included hardware. The 3-wire pigtail hardwires directly to your trailer—no complex harness needed. Red goes to stop/turn, black to tail, white to ground—simple and solid connections that make installation easy even if you’re tackling it solo in the driveway.

Reliable for the Long Haul: Durable Build with Lifetime LED Warranty

The tough plastic housing and sealed electronics stand up to vibration, impact, and weather exposure for consistent reliability. And with a lifetime warranty on the LEDs, you can count on this light staying bright and functional long after others have failed.

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



by:

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



by:

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.



by:

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



by:

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.



by:

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.



by:

Light was exactly as described. The pictures, and dimensions shown, made it easy to match up with my other light as the serial number on mine wasn't visible. This was a perfect match and 1 year later, it still works like new. As usual, the customer service is great, especially if you end up with Stacy A.



by:

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.



by:

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.



by:

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.



by:

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!



by:

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



by:

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?



by:

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



by:

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



by:

I am replacing the identical trailer light I recently damaged. I have had these lights in my trailer for 5 years since its purchase. They are the best lights I've ever had in a trailer. That's coming from an octogenarian.

These guys are great! Excellent products and awesome service! Thanks a million!

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.



by:

Both lights are working great after a year of lake fishing. From past experience I think they are more prone to problems with salt water. But the warranty support has been terrific.



by:

It works great and is a replacement of the original. The original got water in it, so I hope that doesn’t happen to this one.

The light is still working well after a year.



by:

I somehow lost one of these when the old bracket apparently broke off so I ordered a replacement. I went with the standard shipping thru USPS as UPS shipping was quite a jump in shipping cost. eTrailer said it would arrive Thursday, at first so did USPS. Except it did not show up until late Friday? It was only wrapped in a bubble wrap envelope? Kind of scary for the Post Office these days! Once open, there was a mounting bolt missing. After a bit of shaking it seemed the bolt was inside the light? Sure enough, I found it inside once I removed the 4 screws for the lens. The Tail Light seems to be a quality product, if you can stomach the extra cost, I would recommend UPS shipping!
