This Thinline LED light puts out a clean amber glow using 3 diodes that draw only 0.051 amps at 12.8V. The LEDs last up to 50 times longer than old incandescent bulbs and use far less power. That means crisp visibility with minimal strain on your electrical system and no fragile filaments to worry about breaking.
If your trailer sees wet roads or water ramps, this light is built to handle it. The housing and lens are sonically sealed into a single waterproof unit that keeps moisture, dirt, and corrosion out. Even when submerged, it stays watertight and protects the internal circuit board so your light keeps shining.
You’ll get wide visibility thanks to its PC rating that casts light 90 degrees in each direction from center for a total of 180 degrees of coverage. When properly mounted, it works as both a clearance and side marker light so others can clearly see your trailer from the front or side—ideal for staying visible in traffic or low-light conditions.
The rectangular 2-1/2" x 1-3/16" x 7/8" design gives you mounting flexibility. It accepts industry-standard plugs and can be surface mounted with an open-back or self-grounding bracket, or recessed with a grommet—each sold separately. Whether you’re replacing old lights or building from scratch, it’s easy to mount securely in the setup you prefer.
Made with a tough polycarbonate lens and housing, this light can take on rough use without cracking or fading. It’s DOT compliant for safety standards and serves as a direct replacement for Uni Bond LED1225-3A, Truck Lite 15250Y, Grote 47083, Peterson M153A, and Maxxima M20320Y models—making it a dependable upgrade that fits right in where it’s needed.

Replaced the front and rear side running lights on my trailer. Purchased 2 amber and 2 red. These have the proper connection for my trailer and are very bright. Perfect replacement
Purchesed this item to replace a faulty light on a two year old Bulldog power tongue jack. The original light was a white tri-LED lamp and retailers wanted over $20 for a replacement (plus $16 shipping cost). etrailer sold me this amber unit for a fraction of the cost (including shipping) and the unit fits great. Incidentally, it puts out a fantastic amount of light and might be even better than the original. Thanks etrailer!
The side marker light fit the grommet (also purchased) perfectly. Both were a seamless fit into my trailer.
I had a heck of a time finding this side marker light and as it fit into a specific rubber mount (by another manufacturer) which in turn fit into a specific opening in the trailer's fender and the original light was marked by yet another manufacturer (who no longer makes this model) I was VERY glad to discover Optronics made a perfect replacement. It was exactly as described and fit perfect! The best part is it lights up beautifully! Thanks etrailer, you saved the day!!

Still working fine after being submersed numerous times.
I'm very pleased with these LED replacement lights for the fenders on my cargo trailer.
Before these I had the regular light bulb which I had to replace from time to time. So the last time I needed to replace a bulb about a year ago I decided to go with these LEDs.
Wow what a difference in their brightness.
Before changing to LEDs my lights on the fenders were somewhat dim. Now with the LEDs these lights are bright enough for other divers to see them in the daylight giving me some peace of mind that they see me coming.
There is however one con to them being so bright.
When I have to back my trailer into the driveway at night their brightness blinds me from seeing my wife in back of the trailer guiding me in when using my review mirrors.
But it's OK because now I will just get some LED backup lights for the trailer.
I plan on changing the entire trailer over to LED lights, someday. lol
PS. I love etrailer.com

Its been a year of having these lights on my cargo trailer and Im still loving them. Nice and bright to warn other drivers either in front of me or in back of me the width of my trailer coming down the road. I run them day and night and 99 of all drivers coming head on at me I see they pull over just a little to widen the gap between us as we pass each other. I have a cargo trailer with fenders mounter outside the trailer with a little black plastic rubbery housing that holds the lights. I put the amber light facing forward and the red light facing backwards. Just take the black housing off the fender then pull out the old and install then new. Was a good time to clean up the ground wire connection while I was there too. Took 10 minutes or so per side. Theyre awesome. Getchya some here at etrailer.
The new side marker has not been installed yet, but it looks identical to the one to be replaced. eTrailer had what was needed, easy to order, and shipped quickly. My go to parts for trailer parts.
Exact fit for my boat trailer.
A little pricey, but I expect they will last for many years, unlike the old style with bulbs. Had to purchase the pigtail connectors seperate.
On time and what I ordered
Works well.
The lights are perfect I wanted to switch my side markers to LED and they fit perfectly
Perfect replacement for older Shorelander fender marker light. The connections are more near center than end to help fit wires.
It looks really nice now with the Sealed, Mini Rectangular LED Trailer Clearance, Side Marker Light.
I have been buying from etrailer 15 years or more. Always top information, Always Quality merchandise, "The Go To People"
One amber light connector opening wasn’t drilled deep enough to accommodate the wire plug. I had to drill it out myself and got it to seat all the way down. Next I’ll test them all to make sure they work.
Very bright light, same connectors as my 2001 Shoreland'r boat trailer, just had to plug them in.
Cannot say enough about the staff at etrailer, very helpful.
Much brighter light from all viewing angles than the OEM lights. Easy snap in replacement if it ever fails. The self grounding one-wire base would have made my install easier. The two prong plug I ordered was a tight fit but it worked.
I would recommend etrailer.
Nice and bright, look great. Good quality. Installed with new self grounding housings.
SPLENDID! Popped the old incandescent Side Marker Lights out on my 2008 Triton 21X2 trailer and installed these Thinline LED Clearance and Side Marker Lights (both the AMBER and RED ones). Just Plug-N-Play and my boat trailer looks AWESOME! Shipping was a snap!
Exact replacement for 2008 Skeeter (easy loader) trailer

Great
Fits in rubber gasket for Skeeter ZX 250 trailer
Easy to install and looks to be a exact replacement for the factory installed running lights on my boat trailer.

Light is still working great, would buy again if the need arises.
Perfect match for the broken one on my boat trailer
Boat Trailer: Following a highly successful conversion of the brake/tail & DOT lights, I went ahead with changing the amber running/side maker lights. Working with Hally made ordering smooth and simple. The parts arrived via USPS as expected in excellent condition.
The new LEDs fit perfectly into the OEM housing, so I chose not to change them at this time. THe difference in illumination is just outstanding!!!
I will definitely use eTrailer again with two great experiences on this project.
Seeing the outcome, I cannot explain why it took me so long to decide to convert.

After a year and around 2500 miles, the lights continue to perform flawlessly. It was a good decision to convert to LEDs and I will not wait as long should there be a next time.
Great service! Found specialty parts quickly. When I needed questions answered, quality was evident in all responses. This is my go to partner for all things lights!!
