Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Very nice company to work with,order arrived right on time.installation of new LED lights on my Ranger boat trailer was very easy and quality was as good as original lighting



Still working great!!


I have used these lights on my boat trailer and yes they are submerged in water when launching and reloading the boat and so far there has been no issues at all with the lights and I’m very pleased with them.


I had previously bought yellow LED marker lights and liked how they turned out. Bought more for a different trailer.


Mounted these replacement side markers over a year ago and they are still working like new. They are frequently submerged in both fresh and saltwater. Good quality product.


These were replacement lights for my trailer and they work great. Thanks


So I initially was asked to do a review and I only gave one star because the product never arrived as scheduled. It did arrive today and it was probably the post office fault. I was excited to see that the product matched the old lights. In the description they mentioned a stainless steel base. That's great because it's going on a saltwater boat trailer. After further examining I saw that the stud was steel. Really. My old one had a stainless steel stud or bolt. Come on guys stainless steel base with a steel mounting bolt. The light grounds through the mounting stud. Fortunately I was able to disassemble and swap out for a stainless steel one. I guess this wouldn't be a problem if it wasn't going in saltwater but it is.


These are direct replacement for my boat trailer. They arrived quickly.



Light is still working great on my boat trailer. Even being submerged in the river regularly, still working great.

@Robert We're glad to hear that, thanks!


Very easy to install. Grounds with the same bolt that attaches it to the trailer.


These are great LED replacements for my trailer.


Very bright, very easy install; only reason for 4 stars is bc I just installed them and can't speak for their longevity; I drilled a small hole in my trailer next to the main mounting hole to poke the wire through, so as not to see the wire; looked very nice.



As of the last time I launched which was in November the lights still worked great. They have been fully submersed many times in either fresh or salt water.


I want to thank you for all your help with my trailer you were more helpful than you realize. So this is my trailer for a 22' Flats Cat shallow draft Catamaran. I totally dismantled my trailer and buffed by hand with a wire buffer and sand blasted in some spots and applied multiple coats of some very expensive galvanize paint (Z.R.C.). I installed all new C. E. Smith Carpet (about 80'), seven new LED waterproof lights, new springs, new equalizers, new tongue jack, new wench, new safety chain, new chain brackets, all new SS hardware and a 35' long wiring harness.
I was able to send only one review with a picture of the safety chain and brackets. I'm having a little trouble with the rest..oh some of these items were bought locally or from your competitors, until I found ETRAILER. Your prices were cheaper for the exact same things. Your helpful how to videos were helpful. And Rose, your personal helpful knowledge made my buying experience very pleasant, I actually enjoyed talking to you! Thanks to ETRAILER and specifically to Rose G.


Great source for your trailering needs,as well as customer service.


Exactly as described, great price and arrived quickly. We have ordered many times from etrailer and have always been completely satisfied.


Very easy to install and look great on trailer. Low profile and small but very bright LED's. They really look much better than the old bulb type I had on there before. I have not "dunked" them in the salt water yet but hopefully they will hold up.

Mark B.


the submersible LED trailer lights are still shining as bright as ever despite repeated dunking in salt water for the past year. These have been a great purchase.


Great product so far, bright and matches existing truck Amber LED lights. Easy to install with stud attached and single wire.



Product still works with no problem. Recommended for any use.


I bought these light for a pull behind motorcycle trailer build I was doing and I am pleased to say they have been great! They have been on the trailer for about a year now and I have travelled with the trailer for about 3500 miles now towing it behind my motorcycle. No problems or issues. They draw very little power which is great for a motorcycle charging system.


havent installed them yet but your co has always been good


Timely shipment of the exact items I viewed online and needed to repair my boat trailer. I will go back to etrailer when I need items in the future. Price was also fair. Thanks etrailer.



Lights have worked well with a year in service. I would buy them again based on fit, price and reliability.


Great customer service. part was good quality and reasonable price.


Easy install, superior product!


Easy Install. Worked as expected. Appear to be waterproof.


Price was great, I bought these as extr as!


Nice clearance light


The wrong item was shipped but you rectified that problem with a new part the one that was ordered and I did not even have to ship the wrong one back



The light is working great. The customer service I received is the best part


Just opened my package this morning and the new marker lamps exceed my expectations.

Driving home in the dark last night with three lamps in bad order was not fun.

with the arrival of these new optronics LED marker lights it will be safer for me and those on the road next to my boat trailer.

Thank you, Michelle

Bruce H.


Could not be happier with these LED lights.
