Video Transcript for Wesbar Submersible Trailer Light Review

Today we're going to be taking a look at the Wesbar Submersible Trailer Stop, Turn, and Tail Light. Left hand side part number is 2423006. Right hand part number is 24230056. Here you can see our Wesbar Submersible light. It's going to be a really nice, quality looking light. The left side has a yellow and brown wire off the back, our mounting studs here are going to create the ground for us using the supplied flange nuts. You'll see the clear lens on the bottom there, that's to help illuminate our license plate.

Our license plate would mount right down here, and that light's going to make it shine properly, so it will stay within compliance of all the laws. Now the lens itself, it's going to be about 4.5 inches wide and about the same tall. You can see the center section here, this is going to be the lens for our light. Something that I really like, this outer edge is a reflective surface, so as other lights hit it, it's going to reflect even when no power is going to it. Same for the side, we'll have our turn signal bulb in there, but a nice large reflective surface here as well again for nighttime. Looks like it's about 2 and 7/8 of an inch by about 2 and 1/8 there on the lens. From the very back of the light housing to the front, looks like we're going to have about 2.25 inches there.

From the center of the one mounting stud to the center of the other there, we're going to have about 2 inches. About 12 inch pigtail there on the back should help with making our connections. Now the right hand side is going to be almost identical to the left hand side. The only exception is we're not going to have the clear panel at the bottom, that's going to make this a 6-way light, and this a 7-way or 7-function light, that clear panel adding that 7th function, and our wire is going to be green. That's going to be for the right side of our trailer. Those are the only two variances there in our lights. Now these submersible lights are going to have a gasket.

It's going to go all the way around each our lenses and it's going to be sealed here in the rear. That's going to work out great for marine applications like our boat trailers or personal watercraft trailers, things like that, but it's also going to work out really well for those trailers we might take down gravel roads and stuff, so we're not going to be filling these housings up with any dust or any moisture. T The bulbs themselves are going to sit in a shock guard socket. It's really going to help to extend the life and give us one of those lights we don't always have to worry about. Coming out, plug it in, nothing works, we're always changing bulbs.

This is really going to help out with that issue and give us something that's going to be good and dependable. Installing the light is going to be very easy. We've got our pad here, we're going to put that between the light and our bracket. We'll take our two studs, those are going to go through the pre-drilled holes. The back of that light is going to be flush, so that's going to come right up against the flush bracket and then the back we're going to thread on our flange nuts. We'll want to tighten those down. All right, now we're ready to connect it to our trailer's already existing wiring. We've got our yellow and brown coming back. It doesn't really matter what color your trailer wires are, you just want a running light signal, and you want the blinker and the stop light signal. The running light signal, that needs to be connected to our brown wire coming out of the light. This is one of our de-cah 00:04:03 14-16 gauge heat shrink butt connectors. These are going to offer you superior moisture resistance. Keep anything from getting inside there once we get it shrank down, which we'll show you in just a second here. Strip back the wiring from my trailer. Do the same thing for our break and turn signal. Now I like to use a lighter, but you can also use a heat gun or a little mini torch or whatever you've got handy. Just want to provide some heat there. Those are going to shrink down, and once they squeeze there will be a little bit of gel that comes out at the end there. Make sure we have no issues with our connection whatsoever. We can tuck our wire away, zip tie it up, whatever the case is on your trailer. That's really all there is to installing them, really straightforward. The ground comes from our studs and those flange nuts as they tighten down. As you can see we've got a really nice secure fit there, and it's quiet. We've got that foam insulator in there, it's going to keep it from rattling around or giving us any kind of noises. We'll start with our break, and our blinker, and then our running lights. With everything working as it should that's going to complete our installation of the Wesbar Submersible Stop, Turn, and Tail Light. Part number 2423006 for the left hand and part number 24230056 for the right.

These tail lights were easy to install, and work just as they should. One small item was missing from my order, but they were quick to send the item as soon as I notified them. I used them to replace the original tail lights on my boat trailer which had been destroyed by salt water corrosion. These tail lights are described as “submersible “, which I assumed meant that they were sealed to keep out water. But they were not sealed, so the product description needs to be clearer about the meaning of “submersible “. 540808

The lights are considered submersible because the inside circuitry is sealed to protect it from moisture. There will be drain holes in the lights casing but the inside elements will still be protected when submerged in water.

The lights look good but I only got one set of the rubber cushions and nuts for the two lights. I plan to add them to a boat trailer but now I see that they are rated submersible but are not sealed which is not exactly what I was expecting. 304709

Ask the Experts about this Wesbar Trailer Lights

  • Availability of Light Kit for Boat Trailer Guide On Posts
    Yes we do! For the PVC posts at the rear of your trailer I recommend taking a look at the CE Smith LED Light Kit # CE27656A. These are designed for PVC posts that feature a 2-3/8 inch outer diameter and the included LED lights will simply mount to the top of them for a bright red and amber glow. The wiring coming from each light just needs to be connected to your trailer wiring and you are good to go. I have attached an image of these installed just so you can see how they look in...

  • Recommendation on Lighted Guide Poles Wired As Stoplights
    The CE Smith Post-Style Guide-Ons # CE27740 are lighted poles to help guide your boat on to the trailer. CE Smith does have Light Mounting Brackets for Post-Style Boat Trailer Guide-Ons # CE27650A were you could mount a set of stop lights like # 2423056 for right hand side and # 2423006 for the left hand side. These lights can be wired into the stop lights of the trailer. These lights are submersible and contain gaskets to create a weather tight seal. The CE Smith # CE27740 are the...

  • Is Peterson Square 6-Function Trailer Tail Light # 432200 Submersible in Water
    The Peterson Square 6-Function Trailer Tail Light # 432200 that you referenced is NOT submersible. For a submersible unit like this you can use one of the square lights shown on the included link. Wesbar offers a submersible stud-mount incandescent light similar to the Peterson; part # 2423056 is the righthand light and part # 2423006 is the left.

  • Matching Light to Go with Wesbar Stop/Turn/Tail/ # 2423056
    The part number you referenced, # 2423056, is a trailer tail light. This is the right hand side (passengers side). The matching left hand side is # 2423006. The left hand side has a light at the bottom to illuminate a license plate.

  • Trailer Lights Will Not Work When Truck Lights are On
    This sounds like a ground issue or a possible overload issue. When lights start behaving strangely it is almost always a ground problem. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal...

  • Taillights to Replace Existing Wesbar 50010 on Ez Loader Trailer
    According to Wesbar, that lamp was discontinued around 2000 or so. Wesbar tells me that the # 745369 (3335) lens won't work with your existing lamps. Unfortunately, you'll need to replace the lamps but the good news is that they're not terribly expensive. You wouldn't want to use the # 2823283 as it isn't submersible and would not be the best choice for a boat trailer. I'd recommend going with # 2423056 for the passenger side and # 2423006 for the driver's side.

  • Square Trailer Tail Lights with a Plug Connector for a Shorelander Trailer
    All of the similar trailer tail lights like # 2423056 either have blunt cut wires or you just insert the wiring to the backs of the lights. None have a plug. What you could do is use light # 2423056 (and # 2423006 for the left side) and splice the plug from your old lights to them. You would need to make sure the connection is water tight by using some heat shrink tubing such as # DW05744-5.
