Optronics MCL76 Series LED Marker Clearance Light with Reflex Reflector Red Lens Diagram

Sonically 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 housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.


Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.


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 LED Trailer Clearance Light Review

Speaker 1: Today we're going to review and install the rectangular LED trailer clearance side marker light with four inaudible 00:00:04, part number NCL76AB. This is also available as red, part number NCL76RB. This LED light is from Obtronics. It's designed the side marker light to go on the side of your trailer going up towards the front. Now our red version of the light is designed for clearance light on the side or the back of the trailer.Pretty simple device. Only has two wire hookup, a ground, and a power wire which will go to your running circuit.

Two holes to mount it up to on your trailer. Of crouse you can see the 4 LEDs here in the center. The whole body is light. It doesn't have a separate lens to it at all. This is a little bit larger of a inaudible 00:00:46 lights out there that you're used to but this will put out a lot more light compared to something you might see this on a lot of trailers that are out there.

This is the incandescent version. This has been out for years, this style. Compare it it's going to be a little bit bigger but it's also put out a lot more light and draw a lot less power.Now this lens is also DOT compliant which means it doesn't require a separate reflector on the side of a trailer. We take a look at the bottom here, we can see we have a completely sealed housing that prevents any corrosion of the components on the inside.Let's go ahead and install it on our trailer. Now this is going to be a very simple installation.

We've got a relatively flat surface to work with and you can see we have an existing location from a previous light. So we'll actually use one of our holes here existing and create a new one for the other side.What I like to do first to help hold everything up is I will go ahead and drill a self tapping screw, a number 8 size, that uses a quarter inch nut driver. We'll ground our wire right here. Next we'll go ahead and connect up to this wire here which goes directly to our running lights circuit. Just like any simple wiring, we'll go ahead and strip back the installation.

In this case we'll be using a heat streak butt connector. The heat streak variety is really good for applications. We're going to use it on the outside.Now I'm going to use a heat gun on our connector here. It's better to use a heat gun to apply heat than using a regular lighter. A little bit more controlled application. Let's tuck our wires inside for now. There's also plenty of room behind the lights if you need to do that. We will mark and drill for our second hole. I'm using a drill bit that matches the hole in the light. I believe it's a 13/64. Now we're going to install our hardware. I'm using a number 10 x 32 screw pan head and a matching nut. Run it through our hole. Also a matching lock washer will work just fine. Then our nut. All right we'll just go ahead and tighten down our hardware.We'll apply power and try it out. Turn on some power and see what we got. We can see our individual LEDs here. Nice and bright. It puts out a very bright broad pattern. All right now that'll finish it for our rectangular LED trailer clearance side marker light.

Replaced backend top markers on 5th wheel. Little brighter than old ones and more weather/dust tight. Just right brightness for back end. I did put clear silicone around inside connector just in case. 451156

Bought these lights to replace the old incandescent lights that corroded from water and dirt infiltration. They are much brighter than the incandescent lights they replaced. They are also the exact size and design of the ones they replaced. 543628

  • Replacing Peterson PM130 Incandescent Trailer Lights with LED Versions
  • I will be happy to help you find the right LED replacement lights for your horse trailer. Based on the information you have provided the amber LED replacement is # MCL76AB. The red version is # MCL76RB. Another option is to use Peterson lights # M353A and # M353R. Since lights can sometimes go through design changes the new lights may not have the exact same dimensions as the old lights so that would be why you see slight differences in the measurements between your old lights and these...

As for the ground wire, you will just need to run the ground wire on the light to a clean metal surface. Your current lights are designed to ground through the mounting hardware whereas these are not.

  • How To Attach A Ground Wire To Trailer Frame
  • You will want to use a ring terminal on the ground wire. I have attached a link to our product page for the ring terminals we offer you can check out. The best way to do this is just as you said, drill a hole in the metal surface you want to attach the ground to. Make sure is clean and free of any solvents or grease or dirt and use a sheet metal screw to fasten the ground wire with the ring terminal attached.

  • No Trailer Lights When Connected to a 2010 Dodge Grand Caravan
  • If you are using wiring harness # 118552 on your 2010 Dodge Grand Caravan or really any wiring harness that has a powered converter that draws power from the vehicle battery then you should not have a problem with LED lights on a trailer or tester. But if you are using a wiring harness that draws all the power through the tail light wiring only then the vehicle wiring may not be rated for the additional power draw, even from LED lights (if there are enough of them). It is also possible...
