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.

Everything arrived in perfect order and exactly as I was hoping for. I will get these parts installed on our horse trailer soon and will attach pictures once completed. I also will be ordering a few more items for my new pop up once I get it home and see exactly what it needs. Looking forward to fixing that up as well. 804047

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

Ask the Experts about this Optronics Trailer Lights

  • Red Version of Amber Clearance Light # MCL44AB1
    Yes, we have the red version of the # MCL44AB1 as part # MCL44RB1.

  • 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.

  • 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.

  • 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...

  • 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.

  • 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.

  • 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.

  • 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.

  • 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....

  • 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....
