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 circuit board is sealed, which means that water will not 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.

Video Transcript for Optronics Trucks and Trailer Identification Light Bar Installation

Today we're gonna take a look at the Optronics Sealed 3 Light Truck and Trailer Identification Light Bar, with the black base. Offering red lens lights. Part number is MC93RB. Now the light itself is gonna measure 16" from one end to the other. It's gonna be about an inch and 1/2 tall. And it's gonna come up off the trailer from your mounting surface about an inch and 5/8th.

And just like most of lights designed in this style, our mounting holes from center to center are gonna be 7 1/2". That should allow this light to work out in just about any application.Now the light's designed to be either a truck or a trailer identification light. Typically, these are required on trailers that are wider than 80", just to give you kind of a heads up, or so people know. I think it's a great addition on a lot of different trailers. Gives you a nice look here in the back, and just a few more lights back there to help people see what's going on.

Now each of our lenses is replaceable. You can simply remove this light out, pull the plug, put a new one in, plug it back in. So if you do happen to back into anything or one of them gets damaged, you can just replace one of the lights rather than going through and replacing the entire bar.Now the lights are completely sealed. So there's gonna be no moisture getting inside of the lens. That's a big benefit.

Trailers, you know, we drag them down the highway all the time. Moisture and stuff can try to creep in there. Or especially if you're using it on marine application, it's not something you're gonna have to worry about. The light itself offers a two wire design. So we've got one ground wire.

I attach it right underneath the stud as we put it in. That's gonna give us the ground we need. And it has a 50" lead to help run it over and make the connection to your tail light signal. Now this is designed using incandescent lights. Incandescent lights are the traditional style lights we tend to see on trailers. The rest of the lights on here we're incandescent, so we just replaced that.Another option available, part number MCL93RB, is gonna be the LED version. So if you have LED lights on your trailer, that's gonna be a better option for you, so it'll match. Or if you're completely rewiring a trailer, might be a good idea to go with LEDS, they give you a little bit more of a clean updated look. They don't draw as much power through the vehicle. And they tend to last longer. Now to mount our ID light, we've got two holes, one in between each of the outside lights here. We're gonna use this and some self tapping screws. We're just gonna use #12 self tapping screws and mount it to our trailer. These are recessed in there so you don't have to worry about the heads sticking up beyond the light.As you do this, you can see the longer lead. This is designed to help you to get over to one of your tail lights and connect to that running light circuit. So you'll want to choose, when mounting this, to either run your wire down and out, or you can make a hole in behind this. Like you see, we've got a couple extra holes here, so we're gonna try to use one of those to run our wiring through, so it'll all be in behind our light. You can see our white wire is gonna be for ground. You can also use a self tapping screw to connect that in somewhere behind the light. That's something you'll probably find easier. Just to line it up with one of your attachment point holes.And as that screw goes through, as you'll see here in a second, when we tighten that down, that's gonna make our ground for us. I'll just get one side started, so I can get all my slack out. We want it all to be hidden in behind our light there. Just like that. Now to complete our installation of our light, we just need to get our two wires connected. This is gonna be the wire coming from our tail light. We made a jumper there to make sure we had enough length. Strip both sides back, and we're gonna use part number DW05744 to make the connection. That'll be a heat shrink butt connector. It's gonna eliminate the risk of dust getting in there, holding moisture, causing rust and corrosion, which eventually leads to failure.Once we're sure we've got a good connection, then we'll shrink that down. I'm using a lighter, you can also use a heat gun or a mini torch. You just don't want to over heat it. You just want to get it warm enough where it starts shrinking. And you'll notice that that wire looks like it gets larger. And there's a little bit of that clear gel that comes out of the end, that'll indicate that you got a good seal there. We'll do the same thing on the other side. Now we've added on just a little bit of extra wire to our pigtail here. Use that same heat shrink butt connector we've used for all of our other splices.Then we're gonna add a small ring terminal onto the opposite end of that. Then we'll just make our attachment. Just like that. Now at this point, our wiring's ready for use. Something I do like to do, though, I like to start with some electrical tape here. Just kind of go all the way back so we've got just kind of a single wire here at the front rather than 5 different ones. Now to test out our installation, we're gonna use either a trailer tester, or you can simply plug it into your towing vehicle.We'll turn on our running lights. We want to check and make sure those are all working. We can do our left turn signal. We can do our brake lights. And our right turn signal. Now to test out our trailer ID lights, we can either plug it into our towing vehicle or use a trailer tester. But it should come one when you turn on the running lights. And that's gonna complete our look at the Optronics Sealed 3 Light Tuck and Trailer Identification Light Bar, part number MC93RB.

I have order twice from e-trailer. Each time it was a great experience. The best thing was that they kept me in the loop on delivery. One item needed to be ordered from the manufacturer of the part. E-trailer notified me immediately of the situation and set proper expectations on delivery. It still came a few days earlier than what I was told. Great job! 160678

Replaced the original light bar with this one and was able to reuse the existing wire harness rather than splice in the one that came with the replacement. Only had to drill two holes (into aluminum - no big deal) since the old holes didn't match up. 103017
