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.

by: is quite possibly the most dependable site on the internet. I was trying to match a broken side marker light on my trailer and a general internet search was largely unusable. I went to etrailer as I had in the past and the site stepped me through options and categories and gave me the precise match I wanted - quickly. The product is basic, finding it was the challenge. I'm more than satisfied with it.


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.


Great selection so I was able to find the exact replacement. Pricing was competitive and delivery was as promised. What else can a customer ask for?


Great item, highly recommend it. Optronics peoducts last a long time. Just replaced my first one since 2012.


Works great ,a great job too all at etr ailer.

When I think trailer,I go to etrailer

Lights were perfect for my utility trai ler


Super bright. Will buy more. Perfect for boat trailer


Great LED clearance lights, replaced old ones on my boat trailer. These are far
brighter, and more dependable than the old bulbs that rarely worked. Very happy with theses lights

Still going strong, no checking bulbs or connectors this season, all my LEDs are working great, hook up and go!
William A - 04/28/2021


Just what I needed.


These LEDs are great. I replaced my original OEM incandescent lights on my 1994 galvanized boat trailer with these lights.


Just what I ordered and needed , neatly packaged, on time
Thanks JW


worked great


I replaced lights on my boat trailerwith these lights,the others were bad.these led's installed without a hitch and are much brighter than the old one's.haven't had boat in the water yet but so far so good.

working fine.

I will send pics as soon as we get the airboat off the trailer, paint trailer new bunks and install new lights and wiring. I have the lights on our bass boat trailer, we replaced them 6 years ago and the quality is the best I could find.


Replaced the boat trailer lights and bunk boards, fenders and added a set of guide post and rachet straps, now my boat trailer lights up like achristmas tree and has never been easer to launch and load, thanks etrailer, great products fast shipping and great customer service, accidently ordered the wrong size fenders and the folks at etrailer got me the right ones, fast, easy and couldn't have had a better experience, thanks again


Item was perfect, looked all over town, will buy more soon


Have bought from before and once again superb company to buy from.


Great to have a one stop shop!


These Stud Mount LED Clearance lights are what I need for my boat trailer and had them in stock. Mind you they are priced in the "Average " range, but what good is cheaper if they do not have them in stock? I ordered them and they showed up. This I can work with. The service is good............I would give an "Excellent but these lights have a tendency to fail after about two to three seasons no matter how fastidious your installation.


Ordered a spare red marker light to have on hand. Just replaced an amber side light, and planned ahead...... May as well have one of each on hand for...... just in case when the time comes!

These lights are simple to install, and the wire lead is nice and long to make connecting to your trailer harness a breeze.

I will certainly do business with etrailer again in the future!


Excellent replacement for a damaged light on my trailer. Now LED lights are an upgrade from original. Probably not feasible given a variety of applications, but a plug in tip would avoid the need for splicing the wire. Overall, a good product and easy replacement installation.


Fast Service Fast Shipping 5 Stars Bright/Easy installation Looks Great Thank you


Nice product. long wiring pigtail of what looks like 18G wire. 3 LED's that are nice and bright and much better than the Wesbar incandescent light it replaced. Enclosure seems to be well sealed but I would have liked it better if the rear face had the wiring enclosed in epoxy. Metric 10mm mounting stud.


This single mount side marker was unavailable at all my local parts houses, truck stops, and big chain stores. I needed red, single bolt, surface mount LEDs for my boat trailer to be in compliance with state laws and was frustrated not to find them locally.
I should have started at etrailer to begin my search. The products, the price, and the fast service were all exceptional and the fact that I found them in a long lasting, super bright LED, sealed side marker made my deal super satisfactory!


You guys are great! I have a pop up tent trailer made in Canada and I was able to find the exact replacement. It was VERY easy to navigate your web site and I was actually able to zoom in and see the numbers thru the plastic lens and it was a perfect match and at a fair price. I bought 4 extra to have on hand. You are my go-to for trailer parts now...thanks
