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.

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...

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



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.

5/28/2018

Working great



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:

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:

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:

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

Cheryl

These lights are great. Easy to install and 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:

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

Keith H.

7/12/2018

One later and lights still look new and are super bright



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:

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:

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:

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:

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:

Good upgrade over conventional incandescentI looked to upgrade to LED marker lights on a travel trailer after experiencing corrosion issues in the sockets of traditional incandescent marker lights. These LED lights are a good upgrade over the OEM lighs.



by:

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

Still perfect

  • Replacement Lens Cover Recommendation for a Oval LED Trailer Clearance Light # MCL31RB
    Yes, the replacement lens you would want for your # MCL31RB is the part # A31RB.

  • 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.

  • Recommended Round Trailer Fender and Lights for 14 Inch Wheels on 2016 Forest River R-Pod Trailer
    No photo came through, so I did a little research on your trailer to attempt to get the missing visual. 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. You may want to consider the mounting brackets # CE26098G-2 if your mounts were damaged as well. For the marker lights, I don't know the size you need,...

  • Sealing Up Gaps between Trailer Lights and Trailer Body
    What you can do is get some foam from a craft store and make a gasket for each of the lights # MCL31AB and # MCL31RB. Or you can use silicon sealant such as # 0160297 or gasket maker such as # LT37464.

  • Replacement Taillights for Trailer Taillight SAE-P2-A-72
    For an exact replacement we have the part # MCL31RB for a red taillight and part # MCL31AB for an amber light. For just lenses you'd want the part # A31AB for an amber lens and part # A31RB for a red lens.

  • Can Additional Turn Signals Be Installed on the Sides of a Trailer
    As far as turn signals go; that we are aware of there are no restrictions that would prevent you from installing an additional blinker on the side of your trailer in red or amber. You would need to consult your local DOT for more info, but I would be surprised if there were restrictions that would prevent that. Especially since semi-truck trailers often have them. The easiest way to do this would be to use red lights since you could simply tap into the stop/turn circuit on either side...

    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....

  • 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.

  • 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"...

  • 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...

  • Replacement Red Trailer Marker Light for 2013 Trailer Star Boat Trailer
    I was not able to find specs for the marker lights supplied on your Trailer Star boat trailer but I was able to find several photos that show the red oval grommet-mount lights you refer to. There may be a part reference number on the back of the light housing; often this is printed rather than molded into the part. If you can find a part number you can search our site using that, but if its not available you can take a measurement of the actual opening (not the grommet, but the opening...

Other similar lights include LED model # MCL31RB and incandescent model # MC32RB.
