Optronics MCL67AB ThinLine LED Clearance Marker Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.


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.


Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL67AB Review

Today we're going to be taking a look at part number MCL67AB. This is the Optronics Thinline Trailer Clearance or Side Marker Amber LED Light. It's a rectangular light that's going to function either as a clearance light or side marker light. It is going to be sonically sealed with a waterproof lens and housing unit. It's going to feature the amber polycarbonate lens. Again, this is a LED system. It is going to contain three diodes.

LEDs are great; they're going to be great replacements for incandescent lights. They're going to last about 50 times longer. They're going to be more efficient and you don't have to worry about replacing bulbs or brittle filament. It's going to feature a multi diode design; it's going to optimize your light output. It's going to feature the molded plastic housing. These two pieces here disconnect.

This is actually your mounting base. This is going to be your ground connection. It lines up with the mount hole so it's designed to be grounded through mounting hardware. Mounting hardware is going to be sold separately. It's going to mount on the surface of your trailer.

It's got the nice single wire design. You can see on the back of the actual plug it's got the two-prong design. Plugs into the connection there on the base and then it feeds out for just a one-wire connection. This is P2 rated. We're going to take a look at the overall dimensions, including the base. It's going to give us an overall length measuring from edge-to-edge of about 4-1/8".

Measuring this direction, outside edge to outside edge of the light we're looking about 1-1/4" and then going this direction from the very back to the very front we're also looking at about 1-1/4". Here on the backside it's going to expose your mounting holes. These are going to be separated on center by 3". This light is going to draw 0.048 amps at 12.8 volts. Optronics is going to put a lifetime warranty on the LEDs. Real quick I want to go ahead and hook it up to our power source and show you what it looks like with power running to it. Since it mounts through the mounting hardware, I'm going to remove the base and just simply connect directly to the back prongs here. I'll make our ground connection and then we'll connect our power. I'll turn off our overhead light so you can get a better look at that. You can see there it's got three diode design. Produces plenty of light output, nice strong signal, consistent, again LEDs are going to be more efficient. They're going to last a lot longer and they're going to optimize your light output with a multi diode design. That's going to do it for today's review of part number MCL67AB. This is the Thinline Trailer Clearance or Side Marker Light from Optronics.

Thanks for the review, Phil! I have a solution for you! You can replace the black bracket with the Optronics chrome bracket A67CB, or the gray bracket A66pb. This part would better match your trailer. Hope this helps!

I prefer lights that don't need an additional grounding wire. These have a metal bracket on them so when you mount them with your bolt or screw, it grounds the light. Pretty bright light, zero complaints. However I will say i was surprised they don't come with any bolt/nuts or screws. For me that was no big deal since i have both on hand, ended up using some self tapping pan head screws that were zinc plated. To lazy to get the drill set out.. I cut the tip of the connector off and ended up using a heat shrink crimp connector. 505040

Review from a similar Optronics Thinline in Trailer Lights


I bought the series of thin line replacement lights for my 2005 Haulmark trailer. They fit and worked perfectly, are as visible as the originals (with restored color as well - the old ones were sun-faded) while drawing much less power. Now the 5 amp fuse that most cars have for a tail light will safely run all of the tail, clearance, and interior lights on the trailer without blowing the fuse. The first time I plugged in the trailer with the original lights it blew the fuse (without even the interior lights on). Buying these lights was the perfect solution. Now any flat 4-wire plug on any car can be used to operate the trailer. 109589

I have four wires. Probably I can figure out how to wire up the lights, but a brief set of instructions would be nice. 629615

Review from a similar Optronics Thinline in Trailer Lights


Trying to swap out my trailer lights to LED, so the draw on the battery is minimal. There are so many variations on the solid color, I had to measure and keep measuring. The solids have 10 Led’s But no such luck is it’s the fender lights that are both amber and red. I guess one company can’t do it all. It would be great to include the mounting plates, especially at this price. And also to sell multi packs of two or three. I only need two amber and two fender dual color, but need seven red. Shipping was sort of slow compared to today’s shipping speeds. Back in the day it would have been speedy. Times they are a changing. Packaging was weak. Each light has a plastic bag, but maybe only two were still in the bag. Maybe some sort of sealed plastic bag would have been smart. I’m guessing these will work fine. I thought we had to be careful of the Positive and Neutral leads for LED lights because we can damage them if they go on backwards. I guess we shall find out. Thanks etrailer for actually having this product with such extensive documentation and videos. Other websites ain’t got nothin on you. 654219

We do have several light bracket options linked at the bottom of each product page for each light. There are different configurations, and colors to suite your specific needs. At this time we do not offer these lights in a multi-pack configuration.

I ordered four of these MC65RB side marker lights as spares for my Cargo Mate trailer. They arrived in perfect shape. They are a suitable replacement for the old part number 1A-V-1260 running lights that came on my cargo trailer. I have installed one already and it works just like the old one. I would recommend these lights to anyone, 216347

Review from a similar Optronics Thinline in Trailer Lights


I got these to add to the back of a cargo carrier, also from etrailer, to increase visibility. They work very well. There are no instructions so I had to call to ask. For a four pin jack, connect the 3 whites together, both black to the brown from the vehicle , and one red to the yellow(left turn) and the other to green(right turn). Only downside to these lights is that the wires are short so you will likely need to splice additional wire. Not a big deal. Great service as always from etrailer. I never even look elsewhere. 379094

Review from a similar Optronics Thinline in Trailer Lights


I bought my Haulmark 12'x6' Enclosed trailer used a few months back. The trailer was in good shape but the sun faded out the marker lamps. Since I use the trailer as a landscape equipment trailer I'm usually not working at night but now with the daylight savings hour change I find myself getting home when it's dark and now those faded lamps were bugging me. Since I've had great experience in the past with etrailer.com I decided to take the plunge and change out the 14 marker lights to their LED versions...Wow what a difference. Not only are my lamps no longer sun faded but they are bright! Definitely was worth the money and the installation was quick since they simply snap into place. Thanks, RAM 232009

Lights look good at night and are very bright for other drivers to see. I'm reasonably disappointed by the quality/longevity of the product though. I have had continued LED failures on multiple lights and ultimately end up replacing the lights every 10-12 months due to failures. 489246

Ask the Experts about this Optronics Trailer Lights
Do you have a question about this Trailer Light?


  • Can Ground Wire Be Attached To Optronics Trailer Light When Installing
  • If you wish to attach all of your lights to one dedicated ground wire that will work fine for you. Please be aware that modifying the mount in any manner will void the warranty for the light. The # MCL67AB light is designed to be grounded through the mounting hardware. You will want to make sure you do not damage the light base when soldering a ground wire.

  • Replacement Side Marker Light for Wesbar 203260 on Boat Trailer
  • To replace the Wesbar 203260 side lights on your trailer, I recommend looking at the Optronics Thinline Trailer Clearance or Side Marker Light # MCL67AB. This light measures 4-1/8 inches long x 1-1/4 inches wide x 1-3/16 inches deep, which is similar to the dimensions on the Wesbar model which is, as you mentioned, no longer in production. The LED lights will also provide a nice upgrade over the original bulbs. LEDs are brighter, draw a fraction of the power and will last much longer...

  • Can Chrome Base A67CBPG Be Used with Trailer Lights # MCL67RB and # MCL67AB
  • Yes, the lights part # MCL67RB and # MCL67AB can use the chrome base part # A67CBPG that you referenced. The lights come with the black version of this base so you could easily swap it out for the chrome one if you wanted.

  • Dimensions of the Optronics Thin Line LED Marker Light # MCL67AB
  • The Optronics Thin Line LED Marker Light, # MCL67AB, is 4 inches wide and 1-1/4 inches tall. The base measures 4-1/8 inches wide by 1-1/8 inches tall. The screw holes on this light are 3 inches apart on center. I have attached a photo showing the dimensions for you.

  • Troubleshooting New Trailer LED Side Markers Not Working
  • The issue you are having still sounds like there might be a weak or bad ground on the new LED lights. The mix between them and the incandescent assemblies at the rear of the trailer should not be causing this problem so it has to be something specific with the new lights that were installed. Many LED trailer lights feature a 2 wire design (one for ground and one for power) and don't actually use the mounting hardware for its ground like with your old assemblies. If the new lights have...
    view full answer...

  • Why Does a Marker or Clearance Light Only Have One Wire
  • The marker and clearance lights you have now ground with a single wire hence why you have two wires total, one for power and one for ground. If the marker or clearance light only has one wire then this wire is for power and the light grounds though the mounting hardware. When you determine which of the two wires you have is for power, you just simply need to cap the other one off. If the new light with only one wire is installed in a rubber grommet then you will need to run a ground wire...

We have several clearance/marker lights that would work for you, but one of the closest to the 4-3/4 x 1-7/16 x 1-1/4 inch size of the original lamps is part # MCL67AB from Optronics. Instead of bulbs, the lamp uses LED's, which are brighter than incandescent bulbs, but draw a fraction of the power. The lamp measures 3-15/16 in length, 1-1/4 inches height and 7/8 of an inch deep.
