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.

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Video Transcript for Wesbar Mini Clearance and Side Marker Trailer Light Installation

Shane: Hey, everyone. Shane here with Today, I want to walk you through how to install the Wesbar mini side marker clearance trailer light.This is going to be an incandescent light. It's going to work with 12-volt systems. It's going to be a completely sealed system, so it doesn't necessarily have to be used on the top. It's going to be waterproof, so if you have a boat trailer or something like that, you can mount it down on the bottom of the trailer.

So we're not going to have to worry about water getting inside, damaging the bulb. However, the light is replaceable, and it is very easy to replace. The lens does pop off.It's going to have a stainless steel bracket on the back side. We're not going to have to worry about rust and corrosion. When you compare this type of light to a flat light, this light, because it has a rounded top on it, it's going to produce a 90-degree angle of light to either side, to either side of its center line.

So it's going to give you 180 degrees of coverage. So if you have this mounted on the corner, you're going to be able to see it from the front of the trailer and from the opposite side of the trailer.Not only are these available in red, but they're also going to be available in amber. You can find those here at etrailer. As far as the installation side, it's pretty simple and straightforward. Now that we've gone over some of the features, let's walk you through how to get it installed.To start our installation, we need to remove our old light, our old marker light.

This one already has a hole big enough for this to go through. It actually is a little bit bigger. So I'll probably put a flat washer on the inside when I put this nut back on. But what we need to do is to get this wire inside, I'm going to have to drill a small hole next to it.The reason I'm doing it that way rather than running this like this and then drilling a hole under it is so that where we run that wire through in that hole, it's a little bit more sealed. So we'll go ahead and drill that hole.

We just need a hole big enough for the wire to go through. Take our wire, feed it through the hole, get our light set in place, and then we can put our flat washer and our nut on the inside.Now we get all of our wires connected together. We got it connected. We'll test it out and make sure it's working correctly. Once you've tested it and you know it's working correctly, go ahead and seal up any holes you may have in your trailer from your previous light if you're not doing a direct replacement, and you're ready to go.That's going to do it for a look at and installation on the Wesbar mini clearance and side marker trailer light.

Missing the nuts for mounting. Not even in a package.


Easy install works great


Still going strong after a year.


Part arrived and perfect match. The one I replaced on ranger trailer had rubber pigtail so had to splice and shrink wrap but installation was easy enough.

Still operational and working well.

Exact replacement for the running lights on our trailer. Happy with the service and website.

Lights are great! Happy I chose etrailer for my replacement!
Marilyn C - 04/21/2019


Was looking to replace original lights on our boat tailor. I found others until I checked E TRALOR there lights were the prefect match to ones we had . Install was easy with a wire clipping two wires together. They mounted with a secure built in bolt. Works perfect . no assembly of parts they come ready to mount on your tailor.


The light seems to be well made. It was an easy install on my boat. Looking for many trouble free years.

After a year the light is working well!

Bought four for boat trailer, two red and two Amber. They are made fairly cheap but they were cheap. The wax on the back side to make it water proof was so hard when I moved the wire it cracked. Also there were holes in the wax around the bolt where water could get in. I filled the area with silicon to elevate the problem. Also the tin is so thin one crushed onto itself when I tightens he nut onto it. To my surprise they did work. Well you get what you pay for.


Ordered a tire and galvanized rim to use as a spare for my boat trailer. I also ordered some replacement side lights. All products look great. The service from etrailer was first rate. No hassle ordering, very fast process time, quick delivery.
I would recommend etrailer to anyone.


These look and feel like a good light for the money. I'm not a fan of a single bolt mount - holding the light in place. I anticipate having the light being inadvertently knocked off-center. Furthermore, there is not a ground wire on this light, thus you will need to wire the ground to a small screw on the back of the housing - if you have a boat trailer with fiberglass fenders.


This was a marker light for my boat trailer that I could not find locally. I found their website and found it easy to use. Placed the order, it shipped right away and I received it when they said. It was exactly the same as my broken one and fit perfectly. Very satisfied with the whole experience.


Though your service is excellent, I'm not happy with the product. The sidemarker lamps I purchased are really dim compare to the existing sidemarkers on my boat trailer.

Money wise it is not worth it to me to return the product. I'll just purchase the correct exiting lamps at a later date.


Products arrived on time and were high quality. Have ordered from here once before and have not been disappointed.


The only website I found that had the connectors preassembled into the taillight and the only site that had detailed views from multiple angles that showed the connectors. Fast shipping at reasonable prices and great communications from the company.


Just what the doctor ordered. Quick shipping time. Part was of good quality. Very pleased with entire transaction.

Still working as advertised. Good product.
