Optronics MCL44 Series LED Side Marker Clearance Light Diagram

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 Rectangular LED Trailer Clearance and Side Marker Light with Reflector Review

Speaker 1: Today we're going to be taking a look at the Optronics Rectangular LED Trailer Clearance or Side Marker Light with Reflector. The part number is MCL44AB1.As you can see, the LED design is going to give you a much brighter and cleaner light as comparing to the incandescent. These also typically last much longer than what you're going to see with a traditional light, and they won't draw as much power. So, we're not going to have as much power being drawn through the vehicle's system to get all your lights on and activated.Now, the lens, you can see are six diodes here in the middle. That's what gives us our light, but it's also going to be reflectorized. It meets the DOT requirements for a reflector as well as a light, so there's no need for a separate reflector.

Now from one side of the light to the other, you're looking at about 4", then from the top of it to the bottom, you're going to have about 1-1/2", and then from your mounting surface to the further portion out, it's about 15/16".This is going to work out for a direct replacement on most of your side marker or clearance lights, so you can put it in any position you need it. Now, as with most lights in this configuration, our mounting holes are going to be on 3" center. So, for most of the normal lights like this, it's going to be a direct replacement for you.Now, of course, to begin the installation, we need to remove the older existing light. If it has a lens on it, these are just going to pop off. They're going to come off pretty easy.

You'll be able to get in there to your hardware. Traditionally, on these applications they're going to use what's called a double square type of screw, so it has eight points. It's not going to be like the Torx bit. So, what we typically use is just a square bit that'll fit in there properly, and we need to back the screw out. You're going to have one on each side.Pull our light out there.

Now we can trim our old wires off there. Now, do be careful. Sometimes these will want to kind of pop back inside, and that certainly isn't something you want. This one's a little bit short, so we're going to go ahead and just add a butt connector and extend this wire out some. There's plenty of room.

We can tuck it in there. That way we won't have to worry about running out. To extend it, you can use any kind of butt connector you want. We recommend heat-shrink butt connectors just in case there's any moisture, anything like that gets to them. You won't want corrosion.We're going to use part number DW05744, basic heat-shrink butt connector, and then traditionally you'll want to use a 16-gauge wire. You can pick this up on our website. Part number is 16-1-1. That'll be for a one-foot piece, so get what you need. That'll give us more than enough wire to work with. We won't have to worry about it ever being too short in the future. To get this shrink down, you'll want to use a heat source. We're going to use a lighter. You can also use a mini torch or a heat gun. Just be careful to heat it gently. You don't want to put too much heat in one spot at any one time.As you can see, this is a two-wire light setup; however, you can use it on a single wire as well. This is a fiberglass cap, so in a single-wire setup it's not going to work. It's not going to be grounded out. That's why there are two wires here, so we have the ground and we have the power.On the metal sides, if you're replacing a light there, you'll simply place this ring terminal. You can just place that right over the hole, and as tighten your screw down, that creates ground to metal, but since we're on fiberglass, we'll need to use that ground wire. So, we'll just push it out of the back side. Not going to need that terminal, so we'll trim that off and we'll use a butt connector to make our connection just like we will with our power wire.Now, with those stripped back, we can add a butt connector to each one. And then in most situations, your white wire will be your ground, but certainly check it on your trailer and get it hooked up appropriately. All right. Now we can shrink those down just like we did our other ones. Now, we'll slide our wires back in, get our holes lined up. We're just going to reuse the old hardware we removed, put it back in the same hole locations. Once we've got the hardware back in place, we'll just take our cover, place it over, push gently, get it popped on.That's going to complete our look at the Optronics Rectangular LED Trailer Clearance and Side Marker Light, part number MCL44AB1.

Change over from regular lighting system to LED pretty simple. Note, make sure you order the correct wiring system (1 or 2 wire). The 1 wire system can be utilized but will need some adjustments. Front facing markers are so bright you may find it blinding especially when backing up at night. 591232

I bought these to replace the incandescent lights that were on my trailer. It matched my old ones perfectly maybe they were the same company i am not too sure. These are bright at night the color is crisp compared to the old lights. The lens has no rubber seal nor is it one whole piece. The leds themselves are covered in some sort of clear epoxy to make it waterproof. There are 6 leds in the middle i wish they had some pointing to the side so it gives a brighter glow but this style is not bad. Good thing about leds is the long life they have so there is one less thing to worry about. Especially towing late night to the race track the people behind me can see me a good distance away with how bright these are compared to the old lights. 329970

- MCL44AB1

I bought both this and the red colored lights. Product is very easy to install. It serves its purpose by being bright enough as a marker/clearance light without being obnoxiously bright. My only negative comment is the packaging. I bought 4 lights and it was packaged with a crumpled packaging paper on the bottom of the box and all 4 lights was just placed on top of it. I think the lights should have been individually wrapped as there were some light scratches on all the lights when I opened the box. Not really a concern of mine as nobody will ever see the scratch unless looked on very, very closely, but people with major OCD might not like it at all. 206622


Comments

Still works.. Only thing I forgot to mention in my 1st review. The entire light assembly is not sealed. The led circuit board is sealed with some sort of hot glueclear silicone but not the whole assembly. I decided to seal the entire assembly with clear silicone can be bought at any hardware store to prevent the inside of the reflector housing from becoming discolored.

  • Replacement Housings For The GloLight 118a And 117r Trailer Clearance Lights
  • We have both the replacement lens and assemblies for the GloLight 118a and GloLight 117r trailer clearance lights. They are available in both an incandescent part # MC44AB and an LED part # MCL44AB1 bulb for the amber lights. For the red lights, you will need part # MC44RB for the incandescent bulbs and part # MCL44RB for the LED version. The replacement lens assemblies for the amber housings is part # A44AB whereas the replacement lens for the red housings is part # A44RB.

  • Recommendation for Sealed Clearance Lights to Replace Corroded Assemblies on Trailer
  • To replace your existing Optronics # MCL44RB and # MCL44AB1 Clearance Lights with sealed alternatives, I recommend taking a look at the Optronics Sealed LED Trailer Clearance Light - Amber # MCL49AB and Red # MCL49RB. These feature a bit of a different shape than the standard rectangle of your existing assemblies, but they do have very similar dimensions, along with the same 3 inch mounting hole measurement. The lights themselves measure 3-7/8 inches long, 2 inches wide, and 1 inch deep....

  • Availability of Incandescent Version of Optronics # MCL44AB1 LED Trailer Clearance/Side Marker Lamp
  • The incandescent version of the # MCL44AB1 lamp you mentioned is part # MC44AB. The lamp measures 4 by 1-1/2 inches and mounts on 3 inch centers. The lamp is a two wire design, one wire for power, the other for ground. This differs a bit from the LED version that grounds through its mounting hardware.

  • Red Version of Amber Clearance Light # MCL44AB1

  • One Wire Clearance and Side Marker Light Options to Replace Lights on Horton Hauler Trailer
  • We have quite a few different options for trailer clearance lights with one wire and that will ground through the mounting hardware. These lights come in various sizes and shapes. The best replacement for your trailer will depend on the size light you are wanting to replace. For a small LED clearance light that is a stud-mount, you can use the Optronics Sealed Mini Rectangular LED Stud Mount Trailer Clearance Light. For an amber light you will want # MCL95AB and for a red light # MCL95RB....

  • Can Single Wire Clearance Light Be installed To Replace 2-Wire Light On Travel Trailer
  • If a trailer clearance light like part # MCL44AB1 is used, the one wire is the power wire for the light and the light will be grounded through the mounting hardware. If you want to use the ground wire that you have on your trailer you can install part # MCL44AB. This has a 2-wire install, where one is for the power and the second wire is for the ground.

  • Difference Between 1 and 2 Wire Trailer Clearance Lights
  • If where you plan to mount the clearance lights is metal that touches the trailer frame then a 1 wire clearance light would work just fine. The difference between the 1 wire and 2 wire lights is that the 1 wire lights ground through their mounting hardware and the 2 wire lights have to be run to a metal surface of the trailer that touches the frame or to the main ground of the trailer.

  • Replacement Single Wire Trailer Lights that Measure 4 by 1-1/4 Inches
  • We have a couple of lights that are just like that. We have a red clearance light, # MCL44RB1, and an amber clearance light, # MCL44AB1. Both are single wire LED lights that measure 4 by 1-1/4 by 15/16 inches.

  • How to Determine Correct Wiring Connection for Replacement LED Clearance Lights
  • Clearance lights function from the running light circuit (that also powers your tail lights) and since this is typically just a 2-wire hookup the extra wires on your lights could simply be there to allow multiple clearance lights to be wired together. Very often in trailer wiring a white wire serves as ground; based on your photo that would make the green wire the + wire for the running light circuit. You can simply test the light wires on the trailer while you have 12V power connected...

  • Wiring Single Wire Trailer Clearance Lights
  • The single wire clearance lights like # MCL44AB1 will be grounded through the mounting. You can either mount these to the frame of the trailer or structural components connected to the frame of the trailer. The siding or skin of the trailer is not likely to be a good enough ground. You can run a common ground wire to the series of lights used if there is not a good connection between them. I've attached some videos and articles to assist.

  • Installing Optronics LED Trailer Clearance Lights # MCL44RB
  • The Optronics LED Trailer Clearance Lights # MCL44RB that you will be installing on your trailer features a power and ground wire. The black wire coming from the assembly is for power and the white wire is for ground, which will just need to be attached to a clean, bare metal surface on the trailer. It's possible that the two black wires coming from your existing/old assemblies could be used for either ground or power, but I can't be sure of this. When installing the new assemblies...

  • Is the Wiring Accessible Behind the Lens of Optronics Clearance light # MCL22AB1
  • On trailer light # MCL44AB1, beneath the lens where the power wire attaches to the circuitry is sealed. What you would need to do is push the power wire in through the hole in the back, make the cuts and splices needed and push it back through the hole. I made a short video showing you the inside of the light. The same thing applies to the red version of this light.

  • Can Power Wire of the Rectangular LED Trailer Clearance Light be Routed Through Angled Base Hole
  • If you wanted to route the power wire of the # MCL44AB1 through the angled hole on the back of the base of the light you certainly could, but you are going to have to slightly enlarge the hole as the wire will be just barely too thick.
