4-1/8" x 1-1/4" Rectangle. Waterproof, LED trailer light serves as either a side marker light or clearance light. Durable polycarbonate housing and lens. Surface mount with bracket. Single wire grounds through mounting hardware. P2 rated.
Features:
Specs:
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.
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 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.

Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
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.

4-1/8" x 1-1/4" Rectangle. Waterproof, LED trailer light serves as either a side marker light or clearance light. Durable polycarbonate housing and lens. Surface mount with bracket. Single wire grounds through mounting hardware. P2 rated.
Great price and worked good. Wished could have found the light cheaper without black adapter. Rest of trailer is gray. 321995
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!

Laura E - 12/07/2016Working great. As stated wish could have found just the light. Black adapter not being utilized.
Phil S - 01/02/2018I ordered replacement LED lights for a trailer I have . The web site was clear and easy to navigate prices are fair and delivery was prompt. What more can I say? 591957
Replaced DZ part # 77-825 with these new led lights on my 1981 Avion camper. Looks and works great! Video of product mounting was very helpful in choosing these lights. One of the best websites I’ve ever come across. Thanks for the help from your team! 553863
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
Survived a whole year of boating season. Nice and bright. 653752
Again a perfect fit for our Haulmark cargo trailer. These are the OEM equivalent with LED lighting. I installed a white 14 gauge pig-tail wire for extra grounding purposes and they work great. I would buy them again, so thanks again etrailer...... 638556
wish pig tail on light was a little longer had to use a jumper wire to make connection to trailer wire. Other then that their going to work. 610349
This is a good replacement for my boat trailer markers...didn't even have to drill new holes. 607994

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
Heres the color code: White wire for ground Brown wire for backup light Red wire for brake light Black wire for tail light

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.

Dan - 10/30/2014Review from a similar Optronics Thinline in Trailer Lights
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
A year has gone by and the light I installed still operates perfectly. A quality product.

I plan to use two of them for a custom trailer I am building. They have not been hooked up yet, but they look to be exactly as described. They seem to be great quality lights with excellent waterproofing. 411654
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
Review from a similar Optronics Thinline in Trailer Lights
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
Review from a similar Optronics Thinline in Trailer Lights
I am retired for one year as of now and was involved in trucking for all my working years. I have used etrailer for lights , wiring ,trailer items ect... I now have a class a diesel pusher and have gone all LED inside and out and etrailer has had everything I needed and it all worked without any problems. I will use them for all my trailer and electrical needs in the future. 329454
I installed these lights on our 40 ft motor coach and have put on over 40 thousand miles since install. I drive with the lights on all the time day and nite and they still work with no issues. Thank you
Richard H - 01/02/2018Review from a similar Optronics Thinline in Trailer Lights
While I haven't had the chance to put the lights and new spare tire on my trailer, they are all in excellent shape and looks to be good quality! What impressed me THE MOST is the way they were all Packaged together and sent on 1 box!! It was amazing the attention to detail that was spent to make sure my shipment came all together and undamaged from shipping! 142818
They are working great! And look sharp on my trailer! They were easy to install and made the trailer look modern!
