Optronics MCL32 Series Red LED Marker Clearance Light Dimensions

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 Red LED Trailer Light with Reflector Review

Speaker 1: Today we're going to be taking a look at the Optronics Trailer Clearance or Side Marker Light with the Reflex Reflector. This is a three-LED light with a red lens and a black base. The part number is MCL32RBB.Now, there are many reasons that people change out their lights or need new light, whether you've got an old one, the lens is broken on it. Maybe they've kind of modified it. These quick connects aren't usually the best at making a good connection, so that's a good reason to switch them out. Maybe you've got a burnt out bulb or you just want to upgrade to the nicer brighter look that we tend to get out of the LED lights.As you can see, this is going to be a three-LED light.

It gives us a lot of brightness. That's something I really like about the LEDs. They tend to be a brighter clearer light than what you get with incandescence. LEDs also tend to last a lot longer than what you get with the filaments in the incandescent bulbs, and they also use a lot less power. So, same number of LED lights on a trailer will draw less power through your vehicle's system than incandescence.

Something else you'll find unique about this light versus others is that it does have the black base. So, maybe you want it to stand out on a white trailer like or you want something that's going to match your trailer a little bit better, it's a good option to have.Now, overall the light measures 4" from here to here. It's going to be about 2" from the top down to the bot, and it's going to come out from the surface of the trailer about 1". We also have a reflector built into the lens of the light, so not only does it comply with, of course, being a side marker or a running light, but it's also going to work out with the DOT as far as a reflector goes. The black base is an ABS plastic, so it's going to be nice and durable, and if you ever happen to bump the lens or get a crack in it, it is replaceable.

So you can leave your base in place as long as the light still work, of course. You'll just replace that lens.You can see our screws that mount the light to the trailer. We've got one here, one here. These are going to be on a 3" center. That's going to be very common for most of your side marker lights of this size.

Whether you've got a busted lens like what we have, maybe the light's burned out, or you just want to upgrade to LEDs, you can see this is going to be a really good solution. It's more rectangular than the traditional oval style, so that'll give you a nice look.To get that installed, you will need to remove your old light. Now, these have 8-point screws in them, so a Torx bit really doesn't work well in here. What we found is if you don't have the 8-point or the double-square bit, you can use a single-square bit. You can see that'll help us get those right out of there. You're likely to have a wire attached there, of course, so I'm going to trim that and get this one out of the way. As you can see with our wire, we don't have a whole lot of slack here. When you do light replacements, you're going to run into that quite often. So, we need to get this extended.We're going to use a heat-shrink butt connector, part number DW05744. We're also going to use a short length of wire here; 16-gauge will be what typical trailer wiring's going to be. You can get that on our website. That's part number 16-1-1. Now, depending on your application, you may have to open up your hole up a little bit there. You see ours has a pretty narrow hole, so we're going to kind of expand that so we can get our butt connector to slide through.Next, I want to strip the end of that back and then get our connector slid on there, then get it crimped down. Pull on it, make sure you got a good connection there. Then we can add a little extension wire. Not going to need a long piece here. It's not going that far and generally you're not going to need that much wire to make repairs down the road if you have any kind of issues. Now we're going to use a heat source to shrink that down. When it gets all the way shrank down, it almost looks like the wire magnifies. You see a little clear gel come out of the end there. I'll just push that on in. That'll give us plenty of slack to work with.Now, I want to strip back the end of this wire. After that, we'll add another one of our butt connectors. You can use regular butt connectors if you want, but I think the heat-shrink is going to give you superior corrosion resistance. You won't have to worry about moisture and stuff getting in.Now, if you're working with a single-wire system like what we have, your white wire you're going to ground out to the body of the trailer. We'll show you how to do that in a minute, and the black wire you want to hook up to your power lead. If you're running a two-wire system, if you have two wires that come out, we'll you just hook one up to the power and one up to the ground.Start by getting our power wire attached here. Trim a little bit of that back. We're going to one of the same butt connectors we used to extend our wire. We just place that on, make sure we crimp it down really well. Then we'll attach it to our wire there after we strip it back. Now to make our ground to our trailer, we're going to add a small ring terminal onto our white wire. This has been designed for use with 18-gauge wire. You can see we're just going to place that right over the hole. As we bring our mounting screw through, that'll ground it to the trailer.Now, we'll use a heat source to get our butt connector shrank down. We're just going to use heat, kind of gently heat it. It'll turn clear and start to shrink. When it gets shrank down all the way, it'll look like it magnifies, and then when it's all the way at the end, you'll see a little clear gel come out there. Once we've got that shrank, we'll just tuck our wire on in there. If we ever had to make any changes, if we ever have any issues, we'll have plenty of wire to work with.Now, for our ring terminal, we're going to place that just like that, tuck our wire in there behind. We're going to use the original screw that had on there to start there and place that on. We want to bring that in the hole. Now, there is a top side to this light, so be sure you get it in the right spot. This little hoop here should be facing upward. It also says top printed in the top edge. It's just hard to see. Nice and secure. We can put the lens over the light. It says Optronics here, so if you want to have that facing up, it'll go on either way though. There we are. We can test it out.That's going to complete our look at the Optronics Trailer Clearance and Side Marker Light with three LEDs, part number MCL32RBB.

I replaced all the clearance lights and taillights on our fifth wheel camper with these OE style LED versions. They are much brighter and therefore much safer, especially in the case of the tail/brake/turn lights seen elsewhere at etrailer. They should last a lot longer than the original bulb units. I also like the way they look as compared to the old bulb style. Our camper was only a year old, and I don't understand why they all wouldn't come from the factory with LEDs. I installed them all myself without issue. 332749


Comments

Thank you for your follow up. I am still happy with my purchase,although they are installed on a fifth wheel camper trailer that doesnt getused a lot and usually in the daylight hours, so the lights havent got alot of hours on them. So far, so good. Thanks again.

Low power led with good night time visibility. Added 1 of these to each side of cargo box for better side visibility behind the vehicle. Even when light is not on, the built in reflector still provides a measure of added safety which works much better than safety tape which kept peeling off at highway speed. 628728

I’m very happy with these LED tail lights. Bought them to replace the ones that came on the trailer. They are bright and seem to be of high quality. They were easy to install. The only slight drawback is that it’s a bit tricky to get the wires to lay flat enough against the light to get it to sit flush with the back of the trailer. But in the end it worked fine. I would recommend these as a good replacement for older, smaller, incandescent tail lights. 612713

I am actually using these marker lights for tail lights for my Case/Ingersoll Garden tractor.

I am thoroughly pleased. 387919

  • Red LED Version of the Clearance Light MCL32ABB

  • Easy to Install Wiring Harness on 2004 Jeep Liberty
  • Since your 2004 Jeep Liberty does not seem to have the factory 7-way, the easiest to install 4-way that fits your Jeep is the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 42475. You'll only need to plug this into your Jeep's harness, and getting to that is likely going to be the most difficult part as you'll have to remove some interior paneling to find it. Then for lights, I recommend going with LED marker lights. Ten marker lights is quite a bit...

  • Is There a Replacement Lens for Optronics Trailer Clearance Light MC48RB
  • The Optronics Trailer Clearance or Side Marker Light # MC48RB does not have a replacement red lens; if you have this light and the lens was damaged you will need to replace the entire unit. This is an incandescent light and I recommend upgrading to an LED if you do need to replace the light because LED lights are brighter, last longer and will not draw as much power as their incandescent counterparts.

  • Recommended 2 Wire LED Marker Lights for 2015 Four Winds Siesta RV
  • For your 2015 Four Winds Siesta RV, I recommend the Rectangular LED Trailer Clearance and Side Marker Light with Reflex Reflector- Amber # MCL32ABB and Red # MCL32RBB. These are both 2 wire LED lights that will allow you to add marker lights to your current system without issue. You can simply splice these into your current wiring to add the additional lights you desire. For connection, I recommend # 16-1-1 wire and butt connectors # 45330.

  • Replacement LED-Type Rectangular Red Clearance Light for 2001 Newmar RV
  • Based on my research the Hamsar 99063 is an LED-type clearance/marker light with a red lens that is roughly rectangular in shape. We do not carry this brand but we do have an extensive range of trailer lighting that meets these same general characteristics, LED operation, rectangular with a red lens. All are shown on the linked page. These include items such as # MCL32RBB and # MCL44RB1. These do not exactly match your specified dimensions but they are close.
