Optronics MCL31 Series Amber 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 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. 144243

Product came loose in the shipping box with no mounting hardware or installation instructions. After looking at it I figured out the lens pops of and that's how you access the holes to mount it. The light looks like a decent product though, will just have to make a trip to the store for hardware which is a little bit of an inconvenience. 719718

I was very fortunate to have purchased an all fiberglass enclosed motorcycle trailer from a friend who no longer rides. Over the years I have updated to all LED lighting and replaced all hardware to marine grade stainless. I live in the tropics with high humidity and plenty of salt erosion, therefore, this is further protection against corrosion. LED lights purchased from your company we’re not only reasonably priced but excellent quality... 658493

  • Replacement Clearance Light Lens for 1971 Airstream 22 Trailer
    From your picture it looks like you have the clearance light part # MCL31AB which for a replacement amber lens would require the part # A31AB. Then for red you'd want the part # A31RB.

  • 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....

  • How To Mount the Optronics LED Clearance or Side Marker Light w/ Reflex Reflector Part # MCL31AB
    The Optronics LED Clearance or Side Marker Light w/ Reflex Reflector part # MCL31AB mounts by running two screws like part # 1131832 though the base. In order to access these screw holes you will need to remove the lens. I have attached a photo that shows the screw holes. I have also attached an install video for you as well. In order to make the wiring connections you will also need part # DW05714 and part # DW05737-1.

  • Is there a Replacement Lens or Light for TMC GLO-BRITE 2317/2318A
    I do have a solution for you but we do not have a replacement lens that matches your Glo-Lite ID light bar (from what I found the light number 2317 is an ID light bar. If that is not the case please send a picture of the light with the dimensions). We do have many other ID light bars that you could use such as # MC93AB or # MC99AB. Replacing the light is going to be the way to go since the company is out of business.

  • Replacement Side Marker Lights for Southwind RV
    If the Glo-Brite 446A/R side marker lights on your Southwind RV are 4" long x 2" wide you can use # MCL31AB if you need LED lights or you would use # MC38AB for an incandescent replacement. If your Southwinds RV has a different sized or color light, please let me know or send a picture and I can help you find the appropriate replacement light.

  • Trailer LED Tail/Clearance Lights Illuminate at a Low Level Even When Tow Vehicle is Not Running
    It is not unusual for extremely-efficient LED trailer lights to show residual low-level illumination when installed in lighting circuits that originally had incandescent lights. These circuits typically always carry some small amount of power even when the tow vehicle is off. With low-efficiency incandescent type lighting this low power will not be evident as it is not enough to cause those bulbs to light up, but with super-efficient LED lights it can be enough to make them illuminate. The...

  • Can You Swap an LED Clerance Light Directly with an Existing Incandescent Light on A Trailer
    Yes, the Oval LED Trailer Clearance, Side Marker Light, # MCL31AB, can be wired directly into the trailers existing taillight wire, just like the incandescent light you are replacing was wired in. Be sure to ground the white wire with a ring terminal on it to a clean portion of the trailer frame, or splice it into the ground wire on your trailer.

  • 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,...

  • Recommendations For Complete Re-Wiring Of 6 X 12 Enclosed Trailer With LED Lights
    We do have everything you need to re-wire your 6 X 12 enclosed trailer. We also have any of the lights you said you want to use as well. For trailer wiring I recommend installing a 7-way so you can operate the light inside the trailer. The 7-way wiring I recommend is the Hopkins # H20046. This harness is an 8-ft long molded 7-way. I then recommend using a junction box like part # 38656. You would mount this on your trailer and then run your # H20046 wiring into the box. You can...

  • How to Wire Black and White Wires on Side Markers Using Wishbone Harness A35W42B
    To wire a side marker or clearance light that has a two wire design like # MCL31AB, the white wire needs to be grounded to your trailer frame while the black wire which is for power needs to be connected to your running light circuit. On a wishbone style trailer harness like # A35W42B the running light circuit is split into two which is why you see the green/brown on one side and yellow/brown wire on the other side of the trailer. You can simply connect the black wire coming from the...
