No more swapping burnt-out bulbs or dealing with weak illumination. This Thinline LED clearance or side marker light uses 3 red diodes that produce a bright, consistent glow while drawing only 0.048 amps at 12.8V. The LEDs last up to 50 times longer than incandescent lights and don’t rely on fragile filaments. That means stronger light, less power draw, and no bulb changes down the road.
When space is limited, the low-profile Thinline design fits where bulkier lights won’t. Measuring just 4-1/8" long by 1-1/4" tall by 1-3/16" deep, it mounts flat against the surface using the included black bracket. The holes are spaced 3" center-to-center for a simple install on most flat surfaces. The single-wire setup grounds through the mounting hardware, keeping your wiring neat and easy.
This light is built to take on wet conditions without worry. The polycarbonate housing and lens are sonically sealed into one waterproof unit that’s fully submersible. No water sneaks in to corrode connections or damage the diodes, so it’s reliable even after repeated dunking or heavy rain.
For safety and proper signaling, this P2-rated light provides 90 degrees of total beam spread—45 degrees to each side of centerline. Mounted correctly, it functions as either a clearance light or a side marker light. That focused coverage ensures solid front or rear visibility so others can clearly see your trailer in low light.
The polycarbonate lens and housing stand up to bumps, vibration, and weather exposure. It’s tough enough for long-term use without cracking or fading, keeping your trailer lighting sharp and dependable every time you hit the road.

It works lime its supposed to. Ga e it a lower rating because the housing on 3 out of 7 were cracked when I opened them. Didn't have to time go through all the BS with return and waiting for new ones, they all work bit for how long Idk.
Product was as advertised, quick shipping and good price.
Thank you!
Used this product to upgrade from incandesent to led lights. Everything went well and worked great.
Light was easy to install. The Led Replacement light is no longer subject to vibration like the old incandescent lamp. Great people to do business with.
Even though I live in Canada these came very fast, 100% what I wanted. Would definitely recommend etrailer for all your needs.
Great replacement for old faded bulb style lights
Easy to use website with lots pf information. The marker lights are easy to install and are quite bright. They arrived swiftly and all work as advertised. When I need some more I shall return.
Product was just as described, Sales staff was friendly and very knowledgeable about product. Shipping was safe, secure, and reasonable, great experience.
Fast and efficient company to deal with. Got my trailer from them over 10 years ago and getting replacement parts are easily available.
Item was good quality but shipping took a little longer then I thought it should’ve been . Would order again .
good bright l.e.d. lights
Great product but even better customer service. etrailer is now my go to spot for all my trailer needs.
Website is easy to navigate. High quality photos allow me to compare parts and feel confident I've ordered the right one. Part was delivered a week earlier than promised!
Customer Service is second to none. Prompt shipment. Great communication. A pleasure to work with. Side Marker Light was easy to install.
Overhauled all my old bulb trailer lighting to leds. They are bright, clean, and no hassle installation. My trailer is used for night work so visibility matters most to me. Fast reliable sales and service.
Replaced DZ part # 77-825 with these new led lights on my 1981 Avion camper. Looks and works great! Video of product mounting was very helpful in choosing these lights. One of the best websites I’ve ever come across. Thanks for the help from your team!
We manufacture wiring harnesses for a trailer company as well as a light kit for them.
The light is great for our use in this kit. Light is easy to use and install.
Nice product to replace the running lights on my boat trailer.
Mounting holes are close to the existing holes for the old lights.
Very bright.
LEDs should be reliable for a long time.
These lights are not well made. I Cracked one base while riveting it onto my trailer, And cracked a second one when I accidentally installed a red marker where a yellow belongs.- don’t try to remove the lens once clicked into place. They light up, but that’s as much positive as I can give
I had ordered two trailer lights from etrailer and although I received them quickly, one of the frames for the lights was broken when I received them. I took a picture of the broken frame and sent etrailer an email with the picture attached. In about a week to my surprise I received a new tailight in the mail. I have ordered from etrailer before and I have never had an issue, but this was completely unexpected. It is nice to know there are still businesses that put the customer first. I will gladly continue to do business with etrailer. Such a great company. Thank You.
As many know it is difficult to find those electrical/lighting components, and in our case, we needed specific running lights for our horse trailer. After exhaustive searching with trailer manufacturers, we started looking to product suppliers and that is when we found etrailer.com. They had exactly what we needed and a fair price, the service was excellent, including shipping in a timely manner. I bookmarked their site so that I can go back to them for any trailer lighting needs. I gave them 5 stars because they earned it.
Absolutely excellent replacement parts, received on time and in perfect shape. Replaced all the lights (clearance, fender, turn signals, stop, and utility) with much brighter leds. Took about 1 hr to clean up all the contact points and test eveything. Extremely pleased with 'like-new' lighting system! Will send photos by email...
1 year later, working flawlessly. Bright and reliable for my precious cargo in the horse trailer. Kudos to etrailer for their customer service, too.

Still working perfectly. The LEDs are much brighter than the incandescents they replaced, and much more reliable -just what Ive come to expect from E-trailer ...
