Features to know about

Brighter, Longer-Lasting, and Efficient: LED Identification Light Bar

Upgrading from older incandescent lights? This LED identification light bar uses nine diodes (three per light) that last up to 50 times longer and draw less power. At just 0.153 amps at 12.8V, it delivers a bright, crisp red light while keeping your electrical load low. No fragile filaments or bulbs to replace—just dependable LED output every time you hit the road.

Worrying About Water Damage: Fully Submersible and Sealed

If your trailer ever touches water, this light bar is built for it. The housing and red lens are sonically sealed into a single waterproof unit, making it fully submersible. Water can’t get in to corrode the circuit board or damage the diodes, so even after repeated launches or wet roads, your lighting stays protected and working like it should.

Built Tough with Stainless Steel Base

Durability matters when your trailer sees hard use. The 16-1/2" long by 1-3/8" wide light bar mounts to a stainless-steel base that resists rust and holds firm over time. It’s surface mounted for a clean fit, with a center-to-center mounting distance of 16-1/16". The base adds extra strength, keeping the lights steady even on rough terrain.

Simple Two-Wire Hookup for Easy Installation

Installation is straightforward thanks to the 2-wire design—one power lead and one ground wire—with generous 50" leads for flexible routing. Just surface mount it where needed (hardware not included), connect the wires, and you’re done. It’s an exact-fit replacement for Truck Lite #15050R and meets DOT requirements for trailers over 80" wide.

Reliable Lighting for Wide Trailers

This ID bar provides clear identification lighting across the back of wider trailers. With its red lens over white LEDs, 17" overall span, and nine bright diodes, it ensures others can see your trailer clearly in low light or at night. It’s a worry-free lighting upgrade that adds safety, efficiency, and longevity in one clean package.

by:

Replaced the original Carry-On identifier light because over time the aluminum failed. Had to drill new fastener holes and reroute the wiring but nothing hard to do.



by:

During the last Heavy snow storm, a tree limb fell and smashed the clearance light from my stock horse trailer. No other damage. Searched the web and found etrailer. Had the exact same replacement part. Fit perfectly. Five minute replacement job.
Outstanding selection, quality, fast shipping, and prices. Would definitely would buy from again!



by:

This is a great light to replace the broken one on my 2004 Ranger boat trailer. It’s been on several months and continues to work fine. It’s much brighter than the original equipment light. I would buy again if I needed another one.



by:

Every time I have placed an order with etrailer , I have dealt with very friendly and helpful people . My orders have always been shipped very quickly and arrive on time and in great condition . I have nothing but good to say about the company or the products that they carry . I'll be ordering again when I need something for my trailers ect. Thanks for all your help .



by:

Fit perfectly an install was easy. Much easier when the boat was off the trailer.

After one year, still works great. Perfect fit replacement for my boat trailer



by:

Installed this as part of a new trailer rewiring project. Easy to install and much brighter than the original lights.



by:

This was a perfect replacement for the light bar on my Eagle trailer! I didn't even have to drill new holes, the screws fit right in the new light bar exactly where the old one was.
This LED light bar is much brighter than my old light bar.
The stainless steel really makes it pop! See the pictures!



by:

nice lights, easy to install, bright



by:

I changed out my original Wesbar incandescent trailer running lights to LED. The thin line series snapped right into the original base. Looks great and they are water proof.



by:

This unit was not a perfect fit for my 2004 Carson dump trailer, but with a sharp drill bit and cutting oil, it was an easy installation. This has a power and ground wire, unlike the original, but an easy fix as well. Looks good. We will see how it holds up on a construction dump trailer.



by:

The bar fit exactly in the old location and the lights are bright. The only down side is the ground wire which was only two inches long. It had to be installed under the light bar before installing the bar on the trailer. Inconvenient but workable.



by:

I took this item apart so I could paint it to match my flat black trailer. Easy to assemble (good to know for replacements, if needed). Mounting and wiring was a snap, a nice, solid mount, and the lights are well illuminated. I would definitely recommend this product!!!



by:

Quick response, awesome service and fast delivery . Did complete restoration on my utility trailer and these are by far the best led lights for the job . Very happy with the end results. Would recommend this to any dyi person.



by:

I installed this on my trailer immediately upon arrival and took my boat to the lake for the day and when I came home I inspected all my lights and "one" of them has moisture inside of the housing just within one day of lunching the boat. My side marker lights are sealed with epoxy and made in the USA "which I purchased at my local trailer store" and they are perfectly dry inside the housing. Not sure how these are made but they seem like there is no quality control on these led light housings.



by:

Purchased this as replacement for original plastic light bar on my horse trailer. Looks way better, definitely way sturdier and easy install. Another benefit of this stainless steel light bar is that the metal tabs at each end where you screw it to the vehicle have a tiny amount of give so that if the holes don’t line up absolutely perfectly, it may still work. You can’t be off by much (small fraction of an inch as I recall) but with plastic it has to line up EXACTLY or it won’t work. etrailer has a great selection. Would purchase again.



by:

My original and one other replacement were made of plastic. Prop back wash broke both of them.
The stainless unit has worked well and the mounting holes lined up so installation was easy.
Looks good and should for years to come

Light bar is holding up better than new. All of my purchases with etrailer have worked out great and I will continue to use them in the future.



by:

Replaced my plastic frame OEM light because one of the mounting tabs cracked off. This new metal one is durable, LEDs are bright, hole spacing matched the old one, and it looks great.

Thank you for the follow up. I am still satisfied with the light bar and it seems to be holding up with no issues after the first year of use.

I continue to be impressed with this trailer LED. They work all the time and continue to perform while underwater at the boat ramp while launching my boat. Highly recommend.



by:

Still looks great, and more importantly, it has made it through a complete New England season cycle without ONE LED failing! Thing sat buried in snow for weeks, parked with the tail facing North where it gets no sun at all! Stays wet most of the time over there. Through all the heat, humidity, and torrential downpours of New England summers, they still live on. Nice, bright LEDs too.

2 years since the installation, still working great! Glad I bought these.



by:

These are my favorite lights for a long time. I bought the LED lights to replace my old ones that were incandescent bulbs. They are installed under the rear of my Sierra's tail gate.



by:

Great product! One of the few LED ID light bars that I could find that is a direct replacement for my old, broken one, 16” (16 1/4”?) long from center to center of the mounting holes. Easily wired to my boat trailer and I mounted it with stainless steel rivets. Also, was about $10 less expensive than on that other online site, and fast shipping. Very satisfied!



by:

These lights are amazing! They are the brightest LED lights I have found. They are bright in the day time and super bright at night! Easy installment with the videos they have available on their website. I will be shopping with etrailer.com from now on. Best prices around.



by:

Fit perfectly. My trailer was missing this light. Had to research the mounting hole spacing 16” before purchasing this. Was nice not having to drill new holes in the trailer. Very bright.



by:

The identification light bar worked well with a very good fit. Illumination is nice and bright. I replaced this light by heat shrinking the butt connectors as well. The boat trailer manufacture did not waterproof the connectors. Thank you eTrailer.Com for your help and installation videos. Extremely helpful.

  • LED Light Kit for Trailer Over 80 Inches Wide
    The "80" you are referring to is the width of the trailer, and it makes it easier to determine the light kit you need. Since you need tail lights as well as running lights, I recommend the Trailer Light Kit for Trailers Over 80" Wide # TL16RK. This will give you the Stop, turn, tail, side marker, rear clearance, side reflector, rear reflector, and license plate light that you need for your trailer. For the light strip with three lights you were referring to you will need the LED Identification...

  • Recommended U-Bolts, Rollers and Boat Trailer Lighting/Wiring for a 1984 Shoreline Trailer
    Thanks for sending us the pictures! Since you are installing a Bolster-and-swivel-bracket assembly part # CE10001G-4 and need a 4-1/8 inch width by 3-1/2 or 4-inch length U-bolt, we currently don't offer a close match. I would recommend going to a local hardware store to locate a U-bolt with the dimensions you need. I would go with a stainless steel u-bolt because it is corrosion resistant and ideal for marine applications. For the lighting and wiring on your 1984 Shoreline boat trailer,...
