Optronics MCL44 Series LED Marker Clearance Light Dimensions

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.


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! 847687

These lights look great. I purchased them because they also qualified as a reflector as well. While I don't think they reflect light quite as well as a standard reflector, they are great lights. 828830

LED running lights look and work much better than the original ones that came with our Casita travel trailer. Sealing external fixtures with 5200 sealant works and looks much better than silicone sealant and holds up well in all weather conditions. 651148

Product was exactly what I needed to replace my one year old clearance light on my travel trailer. I've also purchased 2 electronic brake controllers and tech support told me exactly what harness I need each time. I give 5 stars to Etrailer for everything I've purchased! 505006

I replaced two failed incandescent marker lights on my RV with these LED units one year ago and they are working very well. They were a direct replacement and needed no modifications. Like all LEDS, they are best seen when looking directly at them (90º) so be sure to choose your mounting location carefully. 437128

The lights are working perfectly. I mounted them on a Lance truck camper to replace the faulty factory units. Thanks for inquiring.

Once again etrailer comes through! I needed a replacement clearance light for my Camplite TT and after scouring the web for my specific application, with no luck, the manufacturer told me to call etrailer. It had been awhile since I ordered from them, but after talking with their sales rep Sal, I was reminded of why their reputation for customer service and application expertise is so well established. Many thanks etrailer and Sal! 386571

Ask the Experts about this Optronics Trailer 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....

  • Can Wiring be Rerouted Through a Hole Drilled in the Center of Optronics LED
    There is room inside the Optronics LED # MCL44RB to reroute the wires but not through the center divot like you're thinking. The circuit board with the diodes is right there and it's glued to the inside of the back housing. The hole you drill has to be outside of the box I've drawn on the back of the light. That box is basically where the circuit board is. With that being said, I don't remember drilling and moving the wires at all. The housing isn't designed to be modified and therefore...

  • Replacement Clearance Lights and SAE Codes On Light Lenses
    The SAE codes on the lens of a light indicate what function(s) that light can perform. Many trailer lights are designed to do more than one function. Based on the SAE codes on the first light, it performs the following functions: A - Rear reflector and P2 - Rear side marker light. I've attached an article with more lighting requirements and information to assist. The best way to determine what you need is actually based on the measurements of your lights. I've linked the page to all...

  • Mounting Method for Optronics Rectangular LED Trailer Clearance Side Marker Light MCL44RB
    The Optronics Rectangular LED Trailer Clearance, Side Marker Light # MCL44RB does not require a mounting plate or bracket since its white mounting base has two holes for screw-mounting to your trailer. Please see the linked image. These mounting holes are spaced at 3-inches on center.

  • Replacement Red Lens for Trailer Clearance Light with SAE P 2A 01 On the Lens
    The numbers on the lens indicate how the light is rated. LED clearance light # MCL44RB does have the same numbers on the lens meaning it carries the same rating. It is likely going to work for you but to be sure take a look at the measurements and compare them to your existing light to make sure they are compatible. Light # MCL44RB is 4 inches long, 1-1/2 inches wide, and 15/15 inches deep. I have linked a video review of this light for you. If you just want the lens then it is # A44RB.

  • Availability of a Trailer Side Marker/Clearance Light that Works on a 12 to 48 Volt System

  • 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...
