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.

  • 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.

  • Replacement Clearance Light for 2020 Mallard M252 Travel Trailer
    In order to find a replacement clearance light for your 2020 Mallard M252 Travel Trailer I recommend taking some measurements. The # MCL31AB is 4" long x 2-1/16" tall x 1" deep. This is an LED light that uses a 2-wire design for power. If this matches your light from the other side in terms of dimension and appearance then it would make a good replacement. If you send me the dimensions of the light on the other side and a picture I would be happy to look for a different replacement if...

  • 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.

  • Replacement Clearance Lights for 2012 Forest River Sunseeker Class C
    We do not have information that tells us specifically what lights are on your 2012 Forest River Sunseeker, so the best way to determine what's going to fit is by providing measurements or a part number off the existing lights. With that said, it looks like you may have something similar to the Optronics LED Clearance or Side Marker Light w/ Reflex Reflector - 6 Diodes - Oval - Amber Lens # MCL31AB. The # MCL31AB is 4" long x 2-1/16" tall x 1" deep with mounting holes 3" apart (center on...

  • Recommended LP Detector Replacement For A 1993 Fleetwood Flair With A 3-Wire Detector
    Hey Brad, The 3-wire design for older LP detectors just included a second power wire (one directly to the battery and one to the DC distribution panel) to ensure that the detector always has power to keep you safe. If you wire one of the two-wire detectors up then you'd just want to run it directly to the battery if you wanted constant power with no chance of a disconnect switch interfering. If you aren't plugged into shore power then only one of those wires should have power from the...

  • 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,...

  • Replacements for 446A/R RV Clearance Lights
    Although we don't offer a replacement lens or a clearance lamp assembly that fits those dimensions, we offer a 6 x 2 inch replacement LED clearance lamp, part # MCL76RB that would last up to 50 times longer than an incandescent lamp, would be much brighter and would only draw a fraction of the power that an incandescent lamp would. I've linked to a product description video for the lamp I recommended.

  • 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 the # MC99AB. Replacing the light is going to be the way to go since the company is out of business.

  • Replacement for Bargman 552 Oval Clearance Light
    According to my research, the Bargman 552 is an oval amber clearance light that measures 3 7/8" long x 1 7/8" wide x 7/8" tall. We do not have an exact replacement for this light but we do have something very close in the Oval LED Trailer Clearance Light part # MCL31RB for red lens and part # MCL31AB for amber lens. They measure 4" long x 2-1/16" wide x 1" tall and will be the best fit replacement we have for you. Please note that finding an exact replacement for old trailer lights 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...

  • 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 then...

  • Recommended Replacement Side Marker Light for Exiss Horse Trailer

You can then click the filters on the page to select your lens shape, color, mounting type, bulb type, etc. You can also narrow the results shown based on the light's...

  • 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.

  • 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.

  • Replacement Taillights for Trailer Taillight SAE-P2-A-72

  • Replacement Light Recommendation for a Bargman Light part # 34-47-802
    The Bargman Light part number 34-47-802 that you referenced was discontinued back in 2013 so there are no replacement parts available for it. For a very similar light to that check out the part # MCL31AB. I attached an install video for you to check out as well.

  • 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.

  • Troubleshooting Running Lights Come On Then Shut Off On Trailer
    It sounds like you either have a weak/bad ground or your lights are drawing too much power. In order to find the problem lets start by double checking the connector on your 2020 GMC Sierra 2500. Using a circuit tester like # PTW2993, check for power on the running light circuit. More than likely you have constant power here and the issue is on the trailer side. If it is on the trailer side I would start by inspecting the connector. Make sure it is free from debris and corrosion. From...
