Optronics MCL31 Series Red LED Side Marker and Clearance Light with Reflex 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 replaced a red LED marker light on my RV a year ago. The original leaked water and failed after about 4 years. It was easy to swap out. It is still dry inside and functions fine.

2-year update: The LED marker light is still dry and continues to function fine. I will definitely buy it again if needed for another location on my RV.

Work great on my motorhome.

Not exactly the light i am trying to ma tch

Well lets get you over to our customer service department for them to help you get the correct light.



by:

Easy install and bright marker light. I also used two on the top back side of my horse trailer as an extra turn signal and brake light. My existing turn signal and brake lights were really low on the trailer and these helped it become more visible when I was slowing down or turning.



by:

I used this side marker to replace existing Bargman 99 series lights on a camping trailer. The Optronics LED model was not quite as bright as I would expect for a 6 diode unit, but still an improvement over the incandescent model. It is larger in size than the Bargman 99 series, so it covers up any surface imperfections on the trailer.



by:

These lights were used to replace the incandescent versions and they worked great.



by:

Look great don’t tho k they will work on boat trailer not water proof



by:

A good light, but there are issues.The LED's emit a yellow light, not white. While the lens is red, it gives the light is almost an umber color and not quite as intense. The potential for a discussion on the color when lit is there. The mounting holes are positioned too close to the center LED compartment to accept hex hex head tapping screws. It's do able but difficult. The light itself is well made with all components includind the 20 guage aluminum wire encased in resin.

John G.

It turns out that the lens had been switched on the light base. The proper base has red LEDs not yellow with a red lens. When paired properly, a bright red light is emitted.



by:

Great job, right part, delivered on tim e.



by:

Great product fast shipping. with the two wires I could mount them on fiberglass with no worries.
Thanks e trailer, great job. lights work great and are very bright...

Jim B.

Lights are great, super bright and no corrosion issues. Exactly as described, great price and great service and shipping.



by:

These are good but I was hoping for more space on the back side to bring the wires through the pre-existing hole in my trailer.



by:

Installed in old light position without a problem. One issue - polarity was not an issue with the old lights but is an issue with the LED'S.

Bob K.

Working great



by:

Lights work great, very bright. Easy wire connect and mounting was a breeze.

These lights are great. Easy to install and bright.



by:

These lights are just what was needed to replace old incandescent lights on a small camping trailer pulled behind a motorcycle. These are bright so as to be seen better by others because motorcycles are sometimes more difficult to see compared to larger vehicles and the LED lights are easer on the motorcycles electrical system. Shipping was prompted, the product is as described by etrailer and arrived in good condition.



by:

LED lights are the way to go. The reflective marker lights are great for times when the lights aren't on yet headlights will reflect off them letting the driver know there is something there. The only thing would be better on these lights would be a better ground.



by:

I installed the lights at full sun. And they are still bright.

Keith H.

One later and lights still look new and are super bright



by:

I ordered some of these previously after a few years of fighting with incandescent bulbs in the trailer marker lights. These LED units are much brighter and will last many times longer than the incandescent units. In my initial order, I had somehow managed to miscount how many I needed, so this order is to replace the last few of the old style markers & bulbs still remaining.



by:

These lights are an excellent upgrade for my pop-up camper. I highly recommend them over incandescents for replacement of old faded marker lights.



by:

Rewired my stock trailer and replaced all the lights with LED. Works and looks great!



by:

Easy to install. Great replacement option for my old lights on my camper. I was surprised that the LED bulbs are red along with the lens.



by:

Good clearance light. Gives off plenty of light at night and in low light situations. etrailer.com has great customer service and will take care of you.



by:

Exact fit! Makes a big difference to a trailer with some age on it. I would highly recommend making the change to the LED lights, the current draw is a lot less and these lamps are bright and clear.



by:

Perfect replacement... identical in fact. Fast delivery, good price.

Ron H.

4/23/2019

Still perfect



by:

These are good lights with pretty secure covers. They work great and bolt up exactly where the old ones did. The only issue I saw was that the wires can easily get pinched when mounting these on a surface with a center hole. These seem to be designed for the wires to be routed out of the side or bottom of the light, not the back. No biggie though.



by:

Great quality. Used on the side rail of utility trailer to bring lighting up to standards.

  • Clearance Light Replacement for Glo Brite 122-Y and 122 R Lights on Trailer
    I have a solution I can provide for you but we do not carry the replacement lens you are looking for. The clearance light part # MCL31AB and # MCL31RB are very close in shape and dimension to the lights you are looking for. They are both 4 inches wide by 2 inches tall. The # MCL31AB is amber in color and the part # MCL31RB is red in color.

  • Comparing Optronics Aero Pro and Glolight Trailer Tail Lights
    There would be a noticeable difference if you had both the Aero Pro light # STL37RB and the Glolight, # STL117RB right next to each other. You would notice that the Glolight seams to actually sort of glow rather than just light up. This is due to the top and bottom bars that light up solid. Both lights are going to be plenty bright. Light # STL37RB has 23 diodes which will be very bright as you can see in the picture submitted by reviewer Becky P. She is using tail lights # STL37RB and...

  • Recommended LED Marker Lights for Trailer Over 80 Inches Wide
    The Trailer Clearance or Side Marker Light w/ Reflex Reflector - LED - 3 Diodes - Red Lens - Black Base # MCL32RBB will have the room to hide wires. The amber lens # MC32ABB is an incandescent bulb. I believe you will want the Oval LED Trailer Clearance, Side Marker Light with Reflector, 6 Diode - Amber # MCL31AB along with the Oval LED Trailer Clearance, Side Marker Light with Reflector, 6 Diode - Red # MCL31RB. For the light bar, I recommend the Sealed, 3-Light Truck, Trailer Identification...

    It looks like you are needing replacement red clearance lights for the rear of your 2001 Dutchmen Travel Trailer. In order to choose replacement assemblies, I recommend taking a couple measurements on your existing units. Based on the picture you provided, something like the Optronics LED Trailer Clearance, Side Marker Light # MCL31RB might be an excellent replacement. This red, LED clearance light measures 4 inches long, 2-1/16 inches wide and 1 inch deep. It features a 2-wire design...

These lights are 6 diode LED clearance lights that measure 2-1/16 inches by 4 inches.

This light is 14-1/16 inches long x 6-15/16 inches wide x 1-1/4 inches thick. It is a recessed mount that has 2 red LED lights and 1 incandescent reverse light for your...

  • Mounting Instructions for Optronics # MCL31RB LED Clearance/Marker Lights
    I'm assuming that you're speaking of the Optronics # MCL31RB side marker/clearance lamps. These lamps are designed to surface mount using machine or self tapping screws as shown in the photo I've provided for you. A gasket isn't available, but using a thin bead of # 0160297 silicone to prevent water from getting behind the lamp would be an excellent idea.

  • Replacement For A SAE-A-P2-72 Trailer Light
    We do offer the Optronics trailer light # MC32RB for red and # MC32AB for amber. These lights will be extremely similar to the # MCL31RB that you mentioned, but they are a bit more square on the ends. The mounting holes on the # MC32RB are 3" apart on center which should be fairly standard. This # MC32AB and # MC32RB appear to be what you are looking for.

  • Replacement Trailer Clearance Light with 3 Inch Centers
    The best replacement clearance light we have for you is the Oval LED Trailer Clearance Light part # MCL31RB for red or part # MCL31AB for amber. This light measures 4" long x 2-1/16" wide x 1" deep and mounts on 3" centers. It has a wire for power and a wire for ground but it won't be much work at all to run the new ground wire. It features 6 LED diodes and has a reflective housing. I have attached review videos for you as well.

  • Recommended Inexpensive Backup Camera for Trailer with Mobile App
    The best inexpensive wireless backup camera we offer that uses your mobile device as the monitor is the VueSMART RV and Trailer Backup Camera part # HM34FR. This unit will mount to a clearance light usually found at the top of the trailer on the outside like the Optronics LED Clearance or Side Marker Light part # MCL31RB. If you don't have one you would just install your own and run power up from the tail lights. This makes for a pretty easy install and then all you'd do is pair the camera...

  • LED Equivalent to Petersen Manufacturing 106A Trailer Clearance/Marker Light
    Although it's not from Petersen Manufacturing like the # 108-15A lens you'd looked at, Optronics makes an LED equivalent that we offer as part # MCL31AB for an amber lens or # MCL31RB for a red lens. Either lamp mounts on 3 inch centers, and is the same 4 x 2 size as the Petersen equivalents. You can see a video showing a typical installation by clicking the provided link.

You may be able to find a model number on the actual housing, or you can measure and send some close up pictures. Looking at pictures I was able to find online, the amber looks like the style of the # MC32AB you were looking at. The LED equivalent would be the # MCL32AB for amber and # MCL31RB for red.

  • Is a Deeper Lens Available for the Optronics MC32 Series Clearance Light to Install LEDs
    We do not have a deeper lens for the Optronics MC32 series clearance lights, however we do have similar LED clearance lights that you may be interested in. Check out the Optronics LED Clearance Light, # MCL45RB or # MCL31RB. These lights have almost identical dimensions as the MC32 lights and will use the same mounting holes on the trailer.

  • LED Replacements for Optronics Rectangular Trailer Clearance Lamp MC32RB
    We do not have an exact LED replacement for the incandescent side marker lamp you mentioned, part # MC32RB, but we have an alternative that is very close. Part # MCL31RB (red lens) and part # MCL31AB (amber lens) are shaped a bit differently than the lamp you referenced. They are also about an 1/8 of an inch wider and thinner in depth. The important dimension, the distance between the mounting holes, is still three inches, so you will be able to use the existing holes. If you click on...

  • Replacemen Glo Brite Amber Clearance Lights for 2009 Sunseeker Trailer
    Based on my research, the Glo Brite clearance lights you currently have mounted to your trailer are very similar in shape and size to the Optronics LED Trailer Clearance Side Marker Light # MCL31AB. This is a very nice, LED amber light that measures 4 inches long, 2-1/16 inches wide, and 1 inch deep. It features a two-wire design and a white base surface that mounts on 3 inch centers. I recommend comparing these dimensions to your existing lights to ensure they will work as replacements....

  • Are Optronics LED Lights Quality Lights
    Lights like the # MCL31AB and # MCL31RB are cheap but that is the nature of a small clearance light in this style. I wouldn't really expect better performance from any other brand. I know it happens, but we don't really see complaints about the lights burning out. Optronics lights are backed by a lifetime warranty on the LEDs so a light like your # BUL52CB is covered under and can be replaced. For the clearance lights I would try switching to the Thinline LED Clearance and Side Marker...

  • Does Optronics # MC66RB Incandescent Trailer Clearance/ Side Market Lamp Include Bulbs
    The Optronics # MC66RB Trailer Clearance/Side Marker Light does indeed include bulbs. Optronics also offers a similar LED lamp, part # MCL31RB. LED lamps draw a fraction of the power of incandescent bulbs, and will last considerably longer.

Since I am not totally sure what the other marker lights are we do have the LED part # MCL31RB which is 4 inch by 2 inch.

  • Recommended Round Trailer Fender and Lights for 14 Inch Wheels on 2016 Forest River R-Pod Trailer

I recommend the CE Smith Single Axle Trailer Fender- 14" Wheels - Qty 1 # CE17900G for your 2016 Forest River R-Pod 180. It will need to be primed and painted black to match your trailer or powder coated like the original fender.

  • LED Lights Won't Work With Incandescent Clearance Marker Lights
    The issue is the different power draws from LED and incandescent lights; it can cause the LED light not to work as the voltage difference between the two hampers the connectivity. To remedy this you will need to install all LED marker or clearance lights. I couldn't find your order to determine the LED you purchased from us initially, so you will need to choose from the size you need like the 4" long x 2-1/16" tall Red Optronics LED Clearance or Side Marker Light # MCL31RB or the 2-1/2"...
