Features to know about

Brighter Visibility Day or Night: 80-Diode LED Power

When you want to be seen clearly, even in daylight, this rectangular LED tail light delivers. It uses 80 individual diodes to put out one of the brightest outputs in its class. The white LEDs shine through a red lens that glows for tail light mode, brightens for braking, and flashes for turn signals. With only 2.2 watts on stop/turn and 0.256 watts on running light, the draw stays low while visibility stays high—perfect for modern electrical systems that monitor current.

Tough Weather Protection: Durable Polycarbonate Build

Rain or rough roads aren’t a problem for this light. The housing and lens are made from weatherproof polycarbonate that stands up to moisture, vibration, and general road wear. You don’t have to worry about cracked lenses or corroded bulbs—these LEDs are sealed up and built to last through years of use without fading or leaking.

Simple Surface Mount Setup: Ready with 6-Wire Pigtail Harness

No complicated brackets or deep cutouts here. The light surface mounts directly onto your trailer and hardwires using the included 6-wire pigtail harness. The wiring gives you full control of stop, tail, and turn circuits without the guesswork. Just line it up, attach it, and secure your ground to clean, bare metal for a solid connection every time.

Extra Safety Built In: Reflective Lens for Added Visibility

Even when the light’s off, safety doesn’t stop working for you. The built-in reflective lens boosts visibility by bouncing back headlights from other drivers, making your trailer easier to spot from any angle. It’s DOT and SAE compliant too, so you know it meets lighting standards for performance and safety out on the road.

Clean Fit and Solid Construction: Wide Rectangular Design

At 11" long, 8" tall, and just 1-1/4" thick, this rectangular light lays flat against your trailer surface without sticking out awkwardly. The low-profile build gives it a clean finished look while still packing in serious brightness and durability—proof that you don’t need bulky housings to get dependable lighting performance.

@Jimmy Nice! Is taillight visibility normally pretty tough in Arizona?


by:

Excellent company. Fast service/shipping. Extremely satisfied with the flush mount LED taillights. Easy install. Thank you trailer.



by:

I would give the product 5 stars except one of the lights only half worked. Working with e-trailer for a replacement. Lights are bright and easy to install after viewing the video.



by:

Excellent light, excellent reflection. Very easy to install. After a long year in the summer sun it still looks brand new!
AND-no bulbs to replace!

The lights still work great! No fading from the sun. Probably the best lights I’ve ever bought.

Excellent LED taillights!
Super Bright

Original lights were dim, especially in bright sunlight

I gave 4 stars because of slow shipping, 10 days is unacceptable.



by:

Terrific! I did however order the wrong part when I ordered. That was my fault. But it actually worked out for the best. Now I have a spare taillight . The part was easy to order, was shipped promptly, and was very reasonable. Thanks RD.



by:

Great Visibility and easy installation. But does not handle extreme vibration well.

You mentioned that it did not handle extreme vibration well and I wanted to ask if you could explain in more detail what happened?



by:

what i've been looking for. This part is exactly what I wanted. Fit is great looks like old lights that I'm replacing. Shipping was quick, two days ahead of estimated delivery. Simple to install.



by:

These are great lights. I replaced my OEM 2017 Forest River Salem lights and the brightness difference is amazing. When I up grade Travel Trailers, These will be one of the first items that i change from now on. The ONLY issue i have is the OEM lights have a license plate tag mount where these do not have that option. You will need to figure that one out.



by:

I love the LED tail lights that I purchased for our travel trailer. Exceptionally bright and they give me a lot more confidence driving down the road both in daylight hours and after dark. The trailer manufactures should be installing these tail lights from the get go. They were easy to hookup and install and the full size foam rubber gasket makes a great seal. The picture you see with my review isn't of the tail lights.



by:

These are an excellent upgrade to standard and obsolete incandescent fixtures on my RV. They are larger and much brighter. The only down side is that my license plate was attached to my old fixture. My fault for not thinking about that ahead of time but it was an easy fix by ordering a new license plate frame with LED.

After a year, still working perfectly.



by:

Good replacement for older trailer without LED lights.
Much brighter easy install



by:

Both replacements fit as intended and were a really nice upgrade from the originals, one of which was ripped off by a concrete pole:)



by:

Overall very happy with the led taillights I just received, good quality, easy wiring, and installation.
The packing was good and free, fast shipping.
As you can see from the pictures I painted the frames to match my trailer.
Thx

Lights are very bright. And easy to install. Make sure you watch the eTraier video as there are no instructions with the lights as to which wire connects to what circuit on your trailer or RV. I checked the lights first using a 12V bench battery do ensure all the LEDs lit up which they did. If you use number 10 self-tapping metal screws for mounting, you will have to bore out the mounting holes ever-so-slightly so if a new install you may want to use size 8 screws. You may want to use an adhesive label to make a tag to identify each circuit on these lights and in the trailer side (see photo). I soldered + heat shrunk all connections for waterproof connections.
