Optronics MCL32 Series 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.

Historically I've always really appreciated Etrailers interface and thoroughness. This time, my items arrived with very haphazard packaging, no bubble wrap or paper, just the lights bouncing into one another for its journey to me. Not a big deal, but annoying none the less and makes you wonder if some potentially weak solder sections could be affected with the needless joslting. Again, small issue, but annoying.

This is my second order of these lights. The first order was a test to see if I like the way they look to replace my old cracked and dirty incandescent lights. Once I put the new lights on my trailer, I knew I had to replace all of my lights because they look so great! They make my old 1999 Jayco look like new!

Solid product. Was a perfect replacement for my OEM light that was broken.

Great. Shining brightly!

Directly fit our old light mounting spot. Eaay install and bright. Camper is visible at night compared to old incandescent bulbs.

Not easy to find a light that is a close match to the set on an older trailer especially LED. This unit appears the same as the original unit.

They sent the incandescent ones instead of the LED that I paid for, took a couple weeks to get the right ones but they are a good quality and easy to install.

Changed out the factory marker lights to these LED markers on our 2018 Grand Design Reflection 5th wheel. Made a big improvement in increased visibility for both daytime and nighttime driving. The installation went well & I found using a putty knife made for easy removal of the original silicone caulk material. I purchased enough of these new LED's in both the red & yellow to change everything out. After doing the first 1/2 of the project I did a comparison with the new LED markers & the original ones and the advantages were quite obvious! Also swapped out the tail/brake lights to LED's & a big improvement there also, along with the added driving safety.

I recently placed two separate orders (the side marker lights and a new jack) with etrailer and both arrived quickly (despite opting for ground shipping) and the quality of the items is great. I wholeheartedly recommend etrailer to anyone needing any type of trailer parts/supplies.

Lights and jack are working great. Would buy again.

I was not satisfied with some of the lenses when the product arrived. Some of them were scratched due to bad packaging. I contacted etrailer and they were willing to send new light assemblies. Due to the fact it was just the lenses I decided that new lenses would be fine. They sent the new lenses immediately. I was very happy with their customer service and am very happy with the product and I plan on doing business with them in the future for some interior lighting upgrades. I have an older motor home and my old clearance lights were cracked and parts for them are becoming hard to find. The new LED lights really look good, are very bright, and I don't have to worry about changing bulbs anymore

Great replacement light.

It will allow to to adjust the tow height of my Coleman Columbia tent trailer. I use two different vehicles and due to the load in them I can level the trailer for easier towing. I give it 6 stars out of 5.

etrailer comes through again! I was pleased and surprised to find these Bargman lights. They are an exact replacement for the Bargman lights in my 1985 Champion Lasalle motorhome. No more fussing with corroded light sockets. These LED lights are much more visible then the original incandescents ever were! Be safe. Be seen.

This is a general review for etrailer. Over the past couple of years I have been ordering parts of various kinds from etrailer. I have been more than satisfied every time. Their products are good, their service is fast, and there is so much helpful information on the website that it takes the guess work out of ordering, and installing products after you receive them. Etrailer is doing a great job as an on-line service. Keep up the great work.

I bought the whole set of LED lights - side and front side marker, tail lights, rear marker bar. It was quite a project getting them all in as they were of course slightly different than the 13-year old originals. But it turned out well and I was very pleased with the quality of all the components.

All trailer parts are doing well. Saltwater even.

Glad to have switch these to new LED, was worried that the three diodes would not be bright enough, they are just fine a bit brighter than the incandescent but not ridiculous. I ordered 7 red and 5 amber, 1 of the amber came with no lens, contacted them and the sent a new light out. they two day shipped which is what I requested 1 due to leaving that week and 2 because I originally paid two day to get them. will order from these guys again due to great customer service.

  • Replacement Trailer Taillight Clearance Lens for Trail-Cruiser 21 by R-vision
    The great thing about RV trailer lighting is that in general all of the lights are made to the same specs and dimensions between brands. So if your camper as what looks like a part # MCL32AB installed on it the correct replacement lens would then be the # A32AB.

  • Correct Replacement Amber and Red Lens for Optronics 4" x 2" Clearance Lights
    There are several different lights which fit the description provided such as the LED Trailer Clearance or Side Marker Light. If this is what you have, the correct replacement lens is part # MCL32AB for amber or part # A32RB for red. I have attached a full list below of 4" x 2" clearance lights by Optronics.

  • How Does Trailer Clearance Light with Three Wires Replace Trailer Light that Uses One Wire
    Sounds like your clearance light is a two function light with two brightness intensities and uses a ground wire whereas your old light grounds through the mounting hardware and is a single brightness intensity setup. So your new light most likely has a white, red, and black wire. The white will be ground and the other two will be different brightnesses. You'll want to test the wires with a 12 volt power source from like a car battery to decide which circuit you want to use for the running...

  • Replacement Lens Needed for Light with SAE-P2-A98 On Lens
    The SAE-P2-A98 that you are referring to is actually tied to different tests that have been done on the light and doesn't reflect the part number of the light itself. We have found that a good number of customers have replaced lights with the SAE-P2-A98 with our part # MCL32AB which measures 2" x 4" (see attached picture). The replacement lens for this light is part # A32AB on our site.

  • Where is Second Wire on Trailer Light Supposed to be Connected to
    If you are installing a light that has 2 wires on your trailer, like the Optronics Rectangular LED Trailer Clearance and Side Marker Light # MCL32AB, then you will want to connect one of the wires to the power wire (sounds like the brown wire no your trailer) and the other will be grounded. Some trailers already have a ground wire that is run to the lights and other times you will need to attach that second wire to a clean, bare metal surface on your trailer using a Ring Terminal, like...

  • How To Mount the LED Trailer Clearance or Side Marker Light MCL32AB
    The Self-Tapping Phillips Head Screw part # 1131832 can be used to secure the LED Trailer Clearance or Side Marker Light part # MCL32AB. This light will require two screws per side. If you also need wiring connectors we have those as well, the Deka Heat Shrink Butt Connector part # DW05743-5.

  • Does the Clearance Light # MCL32AB and the # MCL32RB Have Gaskets

  • Installation of Midship Marker and Turn Signal Light on 1996 Holiday Rambler Endeavor
    Good news! I can help you wire up a mid-ship turn signal your 96 Holiday Rambler Endeavor, but the Optronics light # MCL32AB you asked about will not blink while you have the running lights on. What you will need is the Amber LED Mid-Ship light with flange # STL75AMFB. I recommend using butt connectors # DW05714 and 16 gauge wire # 16-1-1 to make the connection to the diode from the original circuits.

  • How to Wire Trailer Clearance Lights with Black and Red Wires
    The brown wire for your trailer wiring should be for the running lights while the white wire should be for ground. Typically clearance lights use black for power and white for ground, like part # MCL32AB, but in the case of black and red wiring the black is typically ground while the red is for power. This can vary between products but you can simply touch the black power from the light to the white wire from the trailer wiring and then the red wire to your brown wire. If that doesn't...

  • Does Ground Wire Circuit of Trailer Clearance Light Still Need to be Ran on Trailer
    You would still need to ground the ground wire of the clearance light # MCL32AB for it to function. It would be just as easy as running the ground wire to the trailer frame though since the frame has the ground circuit ran to it.

  • What are the Wire Functions for Rectangular LED Trailer Clearance and Side Marker Light MCL32AB

  • Recommended Trailer Lights with Built-In Reflector
    The Optronics trailer light assemblies referenced in your question do not feature built-in reflectors. If needed on your trailer, they will just need to be added separately with these lights installed. For a similar red clearance light that features a built-in reflector, I recommend the Optronics # MCL32RB and for an amber lens you can use # MCL32AB. For a red and white LED tail light, the Bargman Triple Tail Light # 47-84-009 will be a good option. I have attached a few short...

  • LED Upgrade Recommendation for Bargman 59 Series Trailer Clearance Light

  • Recommended Utility Trailer ID Light Bar
    We have what you are after. I have linked the selection we have available. The most common is the LED Identification Light Bar for Trailers part # MCL93RB. This will install to the existing wires you have. I recommend using Heat Shrink Connectors like part # DW05744-5.

  • Is the LED Trailer Clearance or Side Marker Light MCL32AB Offered In Red
    The LED Trailer Clearance or Side Marker Light is offered in both amber as part # MCL32AB and red as part # MCL32RB. These are a pretty standard design so they are a common replacement for both older and newer trailers. Simply attach the power and ground wire at the rear, pop-off the lens, secure the base, then re-secure the lens and you're done.

This kit includes 2 red LED tail lights. These lights will need to be hardwired to your trailer, and have a separate ground wire. For some LED clearance lights the part # MCL32AB would work as well.
