This ThinLine LED tail light packs 15 red LEDs behind a clear lens, giving you bright and efficient lighting for stop, tail, and turn functions. Compared to old incandescent lights, the LEDs last up to 50 times longer and draw less power—just 0.2 amps for stop and 0.01 amps for tail at 12.8V. That means no bulbs to replace and no brittle filaments to break. The durable surface-mount technology circuit board also handles vibration and heat better for long-term reliability.
When space is limited, this low-profile ThinLine light fits where bulkier housings won’t. It measures only 20-1/2" long, 1-1/16" tall, and 3/4" deep—ideal for narrow or recessed installations. The surface-mount design means no need to cut holes into your trailer body; just mount it flat against the surface using your own hardware. With mounting holes spaced 19-5/8" center to center, it installs clean and stays put.
If your trailer hits the water or rides through heavy rain, this light is built to handle it. The housing and lens are sonically sealed into one waterproof unit that keeps out moisture completely. That sealed design protects the diodes and circuit board from corrosion or shorting out, making it perfect for wet or harsh environments where leaks can ruin ordinary lights.
The rugged polycarbonate lens and housing resist impacts, cracks, and UV wear so it holds up well over time. Whether it’s road grime or rough use, this durable construction keeps the LEDs protected and shining bright. It’s also DOT compliant and meets FMVSS requirements for trailers over 80" wide, so you can run it confidently on the road knowing it meets safety standards.
The wiring couldn’t be easier—white for ground, black for tail power, red for stop/turn power. That simple layout keeps installation frustration-free while giving you full function in one sleek package. You can even adapt it for other uses like an identification or clearance light by connecting only the wires you need for that setup. Lifetime warranty on the LEDs seals the deal for a dependable lighting solution.

Ordered two - Five stars even though one had a problem. Called customer service and explained the problem. A replacement is on the way. This is why I do business with etrailer.com. Great customer care, service and quality products. Out of the many orders I have placed this one was the only one with an issue. I'm going to order 4 more next week to install on my headache rack. Great purchase!
The Lights look good on my trailer & were easy to install. They are very visible when lit up. I use my trailer alot at night on the highway. I really appreciate the fast shipping. As always I'm pleased with the product quality & service I received from etraile.
As always great service from etrailer. The lights are bright and easy to install. Put them up high on the back of my trailer so when I’m transporting bikes my tail lights are readily visible.
Finally received them, have not had time to install.
Arrived in a timely manner , product is well made and works great ! Would recommend to anyone!
Great look and bright lights. I especially like that the design of the bar provided a great seal between the light bar and the trailer body when the screws were thightened.
The light matches the one on my trailer perfectly. Joshua was excellent to deal with and was very helpful. THX

Tail light that I was looking for was exact match. Customer service was a huge help in finding it. Would highly recommend this company
Excellent product
And timely delivery
Will continue business as needed
Thanks
My enclosed trailer came with small oblong led lights, they were okay but I felt that I needed more visibility.
I installed these about one year ago. They more than doubled the visibility of my trailer during the day. I highly recommend these lights.

One year later and they are as Bright and trouble free as the day I installed them
They work great, look great, and a breeze to install.
Right part , right price period
As described and fast shipping.
Great product. I just wish it would have come with mounting screws. Im replacing the old lights ones with these new ones. The old screws were rusted out now i have to make a trip for screws
May be the best customer service and company I have dealt with. Product was exactly what I needed, but more importantly as soon as I ordered it Etrailer reached out to let me know there would be a slight delay in delivery due to stock issues and offered me an alternative. I was not in a hurry, but if I was they had me covered. I won't buy trailer parts anywhere else. Thank you for the great customer service Lauren!!!
Thank you for the speedy delivery. I will be installing the new trailer lights next week. I will definitely be doing all my trailer parts needs with Etrailer from now on.

I used these to make my bike rack more visible when the bikes are not being carried.
Replacement for a 2 year old on my trailer that had a bow in it that caused self tapper screw to break and bow out. This replacement is better but still has slight bow. Hope it last's.
Great looking tail lights. Barely visible when not in use due to the clear lens. Love them.
Good, mounted on a hitch basket carrier purchased from etrailer and added a trailer plug so could sync to vehicle tail/brake lights.
They work and look great on the back of my truck. DOT approved and work off my motorhome lights when flat towed behind it. I made the brackets for them and attached them recessed under each side bottom of the rear bumper.
