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.

    Hey Craig, it looks like the closest replacement we have for your no longer available Optronics MCL31RPG is the Optronics LED Clearance or Side Marker Light w/ Reflex Reflector # MCL31RB. This light measures 4" long, 2-1/16" tall, and 1" deep, has 6 diodes, and draws 12.8V at 0.040 amps.

  • 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.

  • Forest River LED Trailer Light Replacements
    For an LED version of the light you sent in a picture of you'd want the part # STL22RB with the grommet part # A70GB. I also attached an install video for this for you to check out as well. 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. For a standard roof vent to fit what you have currently we have the Ventline Ventadome kit part # V2094SP-30 which has a 12 volt fan in it. For interior lighting we have 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,...

  • 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 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...

  • 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...

    Hello James; the Bargman 552 lights you have are no longer around but we do have a similar replacement. The closest match comes from Optronics and measures 4" long x 2-1/16" tall. You can choose from the following based on LED or incandescent and color: -Optronics LED Clearance or Side Marker Light w/ Reflex Reflector - Red Lens # MCL31RB -Optronics Trailer Clearance or Side Marker Light w/ Reflector - Incandescent - Red Lens # MC31RB -Optronics LED Clearance or Side Marker Light w/...

  • Replacement Red Clearance Light for 2012 Keystone Fuzion 5th Wheel Toy Hauler
    I reviewed photos of your 2012 Keystone Fuzion 5th Wheel toy hauler (one is linked) and based on those it looks like the red side light you need is Optronics Trailer Clearance or Side Marker LED Light # MCL32RB which measures 4 x 2 x 1-inch and which mounts on 3-inch centers. Other similar lights include LED model # MCL31RB and incandescent model # MC32RB. Trailer makers do not maintain specs for smaller items like lights so just check your overall light size and mounting hole spacing...

  • 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

  • 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.

  • 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...

  • 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.

  • Recommendation For Tail light And Marker Light LED Upgrade
    Thanks for the information you sent. I did some research on your 1977 Great Divide Camper Trailer and have a few recommendations for you to consider. My recommendations are not exact matches but I believe they will work for you. For the tail light assembly, I recommend the Bargman Triple Tail Light, Item # 47-84-009. 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...

  • 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"...

  • 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.

These lights are 6 diode LED clearance lights that measure 2-1/16 inches by 4 inches. They do come with 2 wires but one of them is a ground that you will attached to a bare metal surface on your trailer. The other wire will be connected to the appropriate wiring on your trailer that your old lights were hooked...
