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.

I've had these on the trailer for a while now, and I'd like to say I would buy more, but I can't - because they're STILL WORKING! I love it when I get a quality product! THANK YOU! 847686

Have had these on my 2007 Winnebago Journey motorhome for a year now. We even struck a bird at highway speed which compressed the fibreglass enough to make the light pop off but we never lost it and just snapped it back in place. Would recommend these. 805080

  • Troubleshooting Trailer Turn Signal on One Side of Trailer Not Activating
    You need to improve the ground on the light assembly that isn't lighting up. It's getting power but when the higher amperage draw is present on it for the turn signal/brake light circuit an insufficient ground is preventing the light from activating. One way to do this is to clean the mounting hardware of the light assembly if it grounds through the hardware or if it uses a wire you can run an additional ground wire from the light to the main ground of the trailer wiring.

  • How To Replace a Trailer Clearance Light With One Wire Using a Light With Two Wires
    If you are replacing a trailer marker/clearance light that only has one wire with a trailer marker/clearance light that has two wires like the part # MCL44AB that means the previous light grounded though the mounting hardware and the new light grounds with a single ground wire. Therefore, the ground wire will just need to be run and attached to the trailer frame. That said, I don't know which color has which function on your light so you will just need to test these for yourself if the...

  • Installing Side Marker Lights on Trailer
    The white wire with the ring terminal attached to the LED Trailer Clearance, Side Marker Light # MCL44AB needs to be grounded to your trailer's frame. It is typically a good idea to run all of the light grounds back to the main trailer ground. The black wire on the light will be spliced into the trailer's running light circuit. Traditionally, the brown wire on your trailer is the circuit the black wire will be spliced into, but using a circuit tester, like # 40376, is helpful to ensure...

  • Installing LED Clearance Lights With 2 Wires
    Two-wire LED clearance lights such as the Red # MCL32RB or the Amber # MCL44AB have one wire for the power lead and one ground wire. The wire that was attached to your old clearance lights will be spliced to the power wire of your new lights. The black is power and white is ground for these lights. If you take a look at the video I have linked you can see how these lights are installed. I have also attached a couple of links to help articles on trailer wiring which you should find useful.

  • How do LED Sidemarker Lights Wire in to Trailer Light Wiring
    When installing a sidemarker light such as this Optronics Trailer Light # MCL44AB you will want to splice into the signal wire for your trailer running lights circuit and then run the ground wire to a clean metal surface. The black wire will be the power wire and the white wire is the ground wire. I attached an FAQ on trailer wiring for you to check out also. I also attached a review video for this product for you to check out. This video shows how the light gets wired and looks when...

  • How to Install New Trailer Lights that Only Have One Wire
    A trailer light that only has 1 wire means that it grounds through its mounting hardware. The single wire is the power wire. The best surface to ground a light to is steel. If steel is not available in the area the light installs you can attach a ring terminal and wire to the grounding stud and attach the other end of the wire to the original ground wire from the old light.

  • Power Getting to Trailer Tail Light with a Good Bulb but the Bulb Does Not Light
    If power is getting all the way to the light and the bulb is good but will not come on that indicates to me that the circuit is not being completed. This would mean the ground is the problem. You can test this pretty easily by attaching the ground from the affected light directly to a negative battery terminal. The light should come on. The lights should be grounded independently and as close to where they are mounted. There should be no corrosion, paint or dirt on the ground location....

  • Replacement for Glo-Brite 118A Trailer Light
    From what I can find the 118A light is an amber light that measures 4 inches long by 1-1/2 inches wide. The light we have with these specs is part # MCL44AB but it's only a 2 wire light. We don't carry Glo-Brite products so I don't have any specific contact numbers to relay for you, but this light should work just fine.

  • Trailer Lights Do Not Light Up But have Power on All Wires
    The problem you are experiencing sounds like a ground issue and/or short circuit. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light but can show up any time. 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...

  • Troubleshooting Trailer Clearance Lights Not Activating After Install
    First thing to check is to verify that 12 volts are making it to the light assemblies with a circuit tester like part # PTW2993. Next you'll need to make sure the lights are grounding properly. The issue is between either the power or the ground for the lights. Most likely the ground though as that is the more common problem. The part # MCL44AB has a black power wire and a white ground wire. Make sure the connection for both of these is solid. If the ground is an issue you can try running...

  • How Do I wire Optronics Rectangular LED Trailer Clearance Side Marker Light to My Trailer
    The Optronics Rectangular LED Trailer Clearance Side Marker has 2 wire leads, a black wire and white wire with a ring terminal. The white wire is the ground wire and should be attached to the trailer frame using the ring terminal. This needs to be direct metal to metal contact. You may be able to use the same ground point as the electric brakes. The black wire is the power wire and should be spliced to the trailer running light circuit. Often times this circuit is a brown wire, but...

  • How to Install Trailer Light part # MC32AB to a Trailer with a Single Power Wire
    Sounds like you bought the # MC32AB and the # MC32RB to replace what you have on your trailer. This is the only style of light we offer in that size. It sounds like your trailer may ground it's light assemblies through the mounting hardware. Which in this case would mean that you would only need to run the ground wire of this light to the mounting hardware and the other to the power wire of your trailer's wiring.

  • Troubleshooting Trailer Lamps That Receive Power But Won't Illuminate
    If you're showing power on the black wire feeding the lamp, and the bulbs are known to be good, the only thing that could cause the lamp not to illuminate is a poor ground connection. You can test this theory by getting a long length of wire and attaching one end to the negative battery terminal of the tow vehicle and touching the other end to the ground wire of the lamp while the running lights are turned on. If the lamp lights, you've confirmed that there's an interruption in the ground...

  • Replacement for GloBrige 118A/117R Amber LED Clearance Light on a 2014 Big Sky Montana
    To replace the right clearance light on your 2014 Big Sky Montana I recommend going with the Amber Optronics # MCL44AB. This isn't a "direct" replacement as this is a 2 wire design, but we actually have a customer review on this product page saying that it is a perfect replacement for the GloBrite 118A/117R LED light that you referenced. I am not sure why your clearance light has 3 wires because a clearance light just carries 1 function. This means that you just need 2 wires; 1 for the...

  • How to Install a Trailer Clearance Light with Different Color Wires
    There are typically only two wires on a clearance light which are for ground and power. There is not a standard wire color to function chart on a trailer for anyone to abide by so it will be best to test them for function with a circuit tester. In order to check this all you need to do is start the vehicle, plug the trailer connector in, and test which of the two wires has power. The light should then specify which wire is for which function but you will again need to test the trailer wiring...

  • After Adding Side Marker Lights to Snowmobile Trailer, Some Work and Some Do Not Work
    Adding the additional lights might be overloading the trailer wiring on the vehicle side. Any given wiring set up is rated for a certain amount of amperage draw. If you try disconnecting the lights that do work and the other ones light up then you know this is probably the problem. There could also be an insufficient ground at the lights that are not working or at the main trailer connector since there is now more current running through the running light circuit. Since a test light...

  • Troubleshooting Lighting on Vehicle that Has Power But Still Doesn't Power On
    If you have power to the bulb on your truck but it's not lighting up that would indicate the issue is the ground of the light assembly. I'd start by checking to see how the ground circuit is connected and make sure it's either connected to a clean metal surface that also touches the frame or is ran back to the negative post of the battery. You can also try connecting the light directly to a vehicle battery power and ground to see if it will work that way just to verify that the light is good.

  • What are the Wire Functions on Rectangular LED Trailer Clearance, Side Marker Light MCL44AB
    On clearance light # MCL44AB, the white wire is the ground wire and the black wire is the power wire. Since there is no standard for wire color and function, you will need to use a circuit tester such as # 40376 to test the wires on your trailer to determine the functions and install accordingly.

  • What Circuit Does the Black Wire of the Trailer Light # MCL44AB Attach To
    If you utility trailer has the standard wiring colors for the circuit functions the black wire of the # MCL44AB would get run to the brown wire as that is the standard color for the running light circuit. If you don't have a brown wire you would want to test the wires with a circuit tester like # PTW2993 when the trailer is connected and the tow vehicle has the running or head lights on. I attached a help article on trailer wiring and a review video for this light as well.

  • Troubleshooting Trailer Wiring on 2004 Chrysler Pacifica
    The easiest way to test your 4-pole wiring on the trailer side is to directly apply 12V power from a battery like the one in your vehicle or a charged spare if you have one. This can be done easily with a set of jumper cables like # HMBC0825 and two short lengths of wire. Connect the negative cable clamp to one piece of wire and the positive to the other. Apply the negative wire to the trailer connector ground pin and then attach the other end of the cables to the battery terminals....

    By discovering that the trailer's hazard lights work perfectly when hooked up to your truck, you have at least narrowed down the problem area to the motorhome and know the wiring on the trailer is good.
