Wesbar LED Waterproof Marker Clearance Light Dimensions

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.

Recessed-Mount Light

Recessed-mount trailer lights install underneath a housing or a grommet (221588 - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Video Transcript for Wesbar LED Side Marker Light Review

Speaker 1: Today we're going to be taking a look at the Wesbar LED Waterproof Grommet Mount Clearance Side Marker Light in amber, part number 47-203667. Now it's also available in red, using part number 47-203668. To help us with our installation, we're going to be using the Wesbar replacement grommet for Wesbar 15 series lights, part number 221588. So here is what our marker light is going to look like. Now it is an LED light, so it is going to be a lot brighter than the incandescent bulbs, and it is waterproof, which makes it perfect for our boat trailer. This is going to be a great replacement for that burnt out incandescent bulb, or if you have a marker light that's missing.

Our marker lights are going to fit perfectly into that Wesbar grommet that are found on most trailers. It's also available in red, for the marker light that's toward the back.Gerardo wrote in, saying it was an excellent product, "Easy to mount on the existing rubber grommet, and the trailer. The electrical connection with easy and flawless to the trailer. It gave a very clean and crisp light." So whether you're looking to replace your marker light because the incandescent bulb keeps burning out, or perhaps you just lost one, our LED marker lights are going to be a great replacement, because they're just going to simply plug into the same harness, and give you a lot cleaner, crisper of a light.The rubber grommet is just going to slide in. It's going to have a little lip on the backside, that's going to grab on.

So if we just kind of push one side in first, you may have to wiggle it in a little bit. It is meant to be a tight fit. Push one side in. Push it back, and just press it in place. Now to make it a little bit easier, I'm going to pull my wire out just enough so I can get the back of the light connected.

It's always a good idea to take a little bit of Dielectric grease, put to on the end of the contacts. Hopefully it will keep out any kind of moisture or corrosion from building up. Then on the back, we're just going to have to contact points that are going to plug into it. So we can just line them up, press it in place.The easiest way to get these lights in, is if you push one side at an angle in. Then you can kind of work from the backside.

Just work the light in around that rubber grommet, because again, it is meant to be a tight fit, so that it doesn't fall out. You may have to get a screwdriver, if you can't get it in by hand. We're just going to press it in place. For our back one, since it is going to be facing the back, we're going to be using a red light. Again, just put a little bit of Dielectric grease on the contact points. Then we can plug our light in. Hook that corner in place, and press the light in.Now that we have this side done, we're going ahead and repeat that, and replace the lights on the other side as well. With our wiring done, and our lights in place, we're going to go ahead and plug it into our tester, so we can make sure that all our lights and wiring our functioning properly. So if I turn my tester on, and put the tail lights on, we can see that all my lights are functioning. So now that we know everything is working properly, we can hook up and hit the road. That will finish up your look at the Wesbar LED Waterproof Grommet Mount Clearance Side Marker Light.

Perfect replacement for the incandescent style. I can always count on etrailer for fast shipping, knowledgeable staff, and great customer service! 397290

- 47-203667

Exact replacement, used the same mounting bolts. Came with a wiring adapter that I didn't have the mate for on the trailer but purchased at a local car parts store (in lieu of cutting off the connector and splicing) which gave me a better install than original. 342304

Perfect replacement for my Wesbar clearance lights which are mounted in grommets on the trailer. 449513

The marker lights I ordered arrived fast and look to be excellent guality. The price of the lights and the shipping cost was very reasonable. I'm very happy with the service of your company. Thank you 443207

Great replacement for the other one that died. I have bright LEDS again. I replaced all of my trailer lights 2 yrs ago with these LEDS. Only 1 went bad, the other got knocked off. I highly recommend these lights as great bright lights making you visible! And look good too 658265

Have bought several items and all have made my boat trailer top-notch. Web site is easy to navigate and customer service is excellent. Prompt and efficient. Time to hit the road and water. 483856

Love the new light. Don't know how I lost the old one. Both it and the surrounding grommet were missing when I got home from my last fishing trip and the wires were just hanging there. After eleven years the rest of the lights on my easy loader trailer are all still working so I can't complain. Anyway, after eleven years, I wasn't sure how well this new light would match up. It is a perfect match, just a lot brighter than the rest. I mean really bright. But since it's a side marker on a single axle trailer, it isn't noticeable until you do your walk around inspection. So just a caution, if you're replacing one of these that sit's next to an identical unit, you might want to replace them as a set. But you certainly won't be disappointed in the performance. 583589

Rewired my trailer last year. Replaced the incandescents with these LEDs. They are plenty bright. Regularly dunked in salt water. Still going strong. 597793

Great Lights! Beat the original incandescent lights 775221

The lights fit into the rubber gromet as they should, and the gromet fit into the trailer like a glove. Shipping was fast! 769806

Switched from bulbs to LED lighting on my boat trailer. Was growing tired of the constant maintenance of bulbs over the years; leakage of supposedly water-tight systems, remembering to disconnect the lights prior to launching and plugging them in prior to driving home. etc. The Optronics lights come with a lifetime warranty. They are sealed systems that will not burn out. The installation is simple... Upon testing the new system, you immediately recognize the incredible brightness and the stepped up brightness of the brake and turn signal lights. From safety, easy install, and low maintenance perspectives, I would recommend the Optronics LED system over the traditional bulbs. No regrets. 745403
