Installed the submersible Led trailer taillights on my unsprung motorcycle trailer. The 4 screws mounting the led/lens to the light housing vibrated loose and lost two of the screws. I made the mistake of trying a loctite thread block on the screws--- big mistake. Loctite crazes and cracked the plastic lens. Finally used silicon sealer adhesive to mount the entire lens/led lights to the brake light housing. All is well after 1 year of longer multi-state trips .
Awesome idea! I've used them for the last several years but, unfortunately, I broke the lens when I hit something. My old ones didn't have replacement lenses, my new one do. If I break them again, it will be a lot cheaper and easier just to replace the lens instead of the whole tailight.
Appears to be of excellent quality and fit. Easy replacement of old bulb type lights. Everyone should retro their lights to LED's. Big safety improvement. Don't have a report on how submersible/water tight these lights will be yet.

Nothing to add, but.... awesome. they are bright and work fine on the boat trailer, even after several dunkings in the lake.
STL9RB & STL8RB Trailer tail-lights. Removed old standard bulb tail-lights, from my small "runaway" camper trailer, and replaced them with these LED tail-lights. The LED lights are much brighter than the old lights. Installation was easy. Followed the instruction video. It took me about twenty minutes from start to finish. They work great and look great.

Still working great.
Looks Great! Works Great! These were added to a 14' Kaufman Dump Trailer that I wanted to use as a utility trailer also, but when completely tarped, the brake/tail/turn lights were covered. So, I added these lights to the side of the frame so that they could be seen when the trailer was securely tarped.

I still love the products purchased
I installed lights on boat trailer in May 2019...
Launched boat several times with water covering lights.
Stored boat and trailer outdoors all winter of 2019/2020.
April 19, 2020 I took boat and trailer to marine shop for maintenance.
LIGHTS WORKED WITHOUT AN ISSUE!
Thank you for selling a reliable, quality product!

Lights still work perfectly after heavy snows during 2020 2021 winter outdoor storage.
Installed this and several other lights on a new trailer. Factory lighting and wiring left a lot to be desired, and with the help of etrailer.com I was able to get everything fixed up like I wanted.
Lights work very well - clear and bright red tail and turn/brake lights.

All of the products I purchased its been about 2 years now are still working great. Thanks for checking in.
Very nice lights for the price. They were easy to install and the mounting bolts fit right into my existing holes from my "different brand" lights that were damaged. They are very bright! Not sure if they are "truly" submersible like the add says, as the wires simply go through a manufactured hole in the back of the case, so the wiring inside must be sealed. Either way, I just filled this hole with some regular silicone caulk. As with all trailer lights I would recommend buying or making light guards, as these lights can break easily. Overall I am happy and would definitely recommend!

Thank you! The lights are great, no issues at all, and tough as nails!!! I have them on a 10k 6x10 dump trailer, that I beat the snot out of, gravel logging roads, mud, snow, ice, driving through brush. I just wish my trailer tires were as tough as those lights. Thanks again, and if I ever need anything for my trailers, I will be shopping etrailer!!!
Very impressed! Ordered the STL9RB and the other side twin STL8RB. Etrailer shipped the wrong twin. One phone call and 5 minutes later, the correct part was shipped!
The LED tail lights and side markers (MCL82ADB Optronics LED Surface Mount Marker/Clearance Lights with Reflex) are for a home-built cargo trailer. Decent build, waterproof, and the plastic is of a heavy gauge to last a long time in the Arizona sun. These units are equipped with LED's, and should last a long time.
Thanks etrailer!

One year in, and tail lights are still holding up well in the Arizona sun . . . . . :-
I have installed the tail light and everything works fine. The delivery was faster than anticipated.
Disappointed, light arrived with broken lens. Then tried to call customer service. No answer. Then emailed, no response.
I've had it for a year and it still works exactly as it should.
Nice product fast shipping. Installed today. Trailer is back to normal
I love the light! It was an identical replacement of the one I had which was broken at the marina where I had the boat serviced last fall. I didn't notice the damage before I stored it this past winter. It had to be replaced. The brightness of these lights is astounding. I had to have one just like the one that was broken.

This is awesome, Joseph! It's always nice to find that perfect fit so that everything still looks the same, just new!
Had to replace the tail light on my motorcycle trailer that vibrated and broke on my last trip (different manufacturer). Just completed a 500 mile trip, including periods of rain. No problems at all. Grat product.
Nice and bright , worked great for my flatbed upgrade .easy website and easy shipping. Ordered from this company for a few years and have never had an issue
Perfect fit for my trailer.

The lights look and work perfectly. No issues
Beautiful tail light. Very bright for the brake and turn signal. Fitted it on the back of my trailer with an L bracket.
Very bright out of the 2 led options for this type light get this one its brighter
Perfect replacement for factory installed lights.
Was able to use factory drilled mounting holes.
Installed in less than 45 minutes. Much brighter than original lights. I believe that they should provide many years of trouble free use.

Its been about a year, the lights have gone through all four seasons here in Minnesota and continue to function flawlessly. They have been a great investment saving me the time and effort needed to replace light bulbs.
Installed the new lights today. Easy peasy. I grew up on a farm, in the country, and have been fixin' and futchin' with trailer lights since I was 6, it seems (I'm 74 now). Hopefully this is the last time I'll need to fix the lights on this particular trailer.
Fit perfectly where the old lights were. Perfect replacement.

So happy to hear that! Thanks for sending a photo too. They look great!
Nice and bright! Worked out great on my trailer.
I’ve bought two trailer lights, one a few years ago, both have worked without fail. The company emailed me for feedback a year after I bought my first light. No company has ever done that. I was impressed they cared about the lasting quality of their product. 5 stars.
I bought the passenger side one to replace an older, broken tail light. It was so good, I immediately ordered the driver's side to have a matched pair!

LED Submersible Trailer Stop, Turn, Tail and License Plate Light. The LH and RH taillights that Ive been using for a year now still work perfectly theyve been submerged hundreds of times! Theyre several times brighter than my old LED lights-a real safety factor! The only thing Id like to see would be a non-license-plate version of the LH unit for states like MN that dont issue trailer license plates. I had to tape over the illuminating lights on that side. A truly great product!
