dimensions of light

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.

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

Could not be happier with these LED lights.

I bought these lights as a replacement on my boat trailer and they have worked well. I have had no issues with water inleakage during the loading and unloading of my boat. They were also very easy to install.


I had a difficult time finding these Trailer marker lights. E-Trailer had them in stock and delivered them quickly. I'm very happy, the match is perfect and i highly recommend E-Trailer for your parts needs.


These lights were a logical, direct replacement for the original incandescent marker lights on my boat trailer. Since the boat is used almost exclusively in saltwater, the sealed light housings were a must. Only time will tell how long they last. I replaced the original incandescent tail light assemblies (they didn't last even one year) on this boat trailer with Optronics LED units about 8 years ago and they have performed well. That good experience with the Optronics brand led me to this purchase.


All items are as they are advertised. Arrived within the timeframe stated. They have stuff others do not carry. etrailer is good to deal with, and they make things good which fall through the cracks, as things sometimes do. Wrong part or whatever.


Easy Install, would like to see stainless fasteners… Backing plate/ bezel is SS. Bought amber as well as red lenses.


Great service. Lights came without mounting hardware but quick response and replacement sent overnight.


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.


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.


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.

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


Great customer service plus fast delivery will buy again what ever I need for my boat trailer thank you.


good stuff reliable delivery thanks etr ailer


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.
Ryan - 02/13/2019


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.
Horacecarter - 02/16/2020


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.

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.
Mark B - 08/26/2014


Lights were easy to install on rear steel plate of trailer. 3 holes drilled per light (2 for mounting, 1 for wire access). Lights are bright and very visible in daylight conditions. Lights are protected by design of rear steel plates. Very satisfied.


Product arrived well packaged and on time. Used them to light up my running boards on a Ram 3500 (went a little retro) Ran these to my 4 pin trailer Harness and they work great. Love the look. Have already recommended to someone else that liked mine. Would order again.


Great product and last a long time. I installed them on my watercraft trailer in 2012. One red just went out due to my negligence, if not for that, it would still be working. I highly recommend Optronis products.


Great LED side markers. Great Price. Quick shipping. Great Company


Outstanding product. Used these to go "retro" and put on my Ram running Boards. Easy install. Just made some holes in pinch weld - ran to 4 pin trailer connection and BAM - all good. Lights delivered quickly and in great shape. Recommend this product.


Package arrived late Fri night or Sat morning which isn’t bad but I don’t know what your processing time is. I never got a confirmation that it had shipped. Everything came in good shape and was installed on trailer. I would use your company again. Thank you for responding to me.


Received quickly but I ordered two lights and one does not work even with direct power to it


Installation was easy. Works great but have not put it in the water yet. Took a little longer than expected with shipping.


Reasonable price, quick delivery, item just as described, good follow-up. I will buy from them again!

Still working great after a year!!!
