Optronics MCL65 Series Thinline LED Marker Clearance 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 - MCL67RB Review

Today we're going to be taking a look at part #MCL67RB, this is the Optronics Thin Line Trailer Clearance or Side-marker Light. It's going to be a red light, because it has the red lens on it, it is submersible and it is an LED system. The rectangular light is going to function either as a clearance light or as a side marker light. It's going to feature a sonically sealed and water-proofed lens housing unit. LED's are great replacements for incandescent lights, they are going to last about 50 x longer, they're going to be much more efficient and you don't have to worry about replacing the bulbs and you don't have to worry about brittle filaments. Now this is going to feature a multi-dialed design, so it's going to optimize your light output. It's going to have the molded plastic housing with the red poly carbonate lens. You can see here on the back side it's got the two pins coming out, those are for the power and ground connection.

It snaps into this bracket, the bracket has the exposed mounting holes, it's going to have a one wired design. This unit is designed to ground through the mounting hardware. Mounting hardware is sold separately. It's really simple. This simply just plugs into those two female ports, and then it snaps into the bracket and it's ready to be mounted. It's designed to be a surface mount so it's going to mount on the surface of the trailer.

Again you got the single wire design, the black wire is going to be for power and then again it grounds through the mounting hardware. This is P2 rated. If we take a look at the measurements, starting with the overall length. Now we are including the bracket in these measurements. That's going to give us a measurement of about 4 inches. Measuring this direction, it's going to give us a measurement of about an 1 1/4.

Then measuring the width here of the bracket, we're looking at about 1 3/16's of an inch. It's got the mounting holes back here, those are going to be separated on center by right at 3 inches. This light draws 0.048 amps at 12.8 volts and Optronics is going to put a lifetime warranty on the LED's. Since the mounting hardware is sold separately, I'm going to go ahead and make our connections directly to the pins coming out of the back here, we're going to run some power to it, that way you can see what it looks like, we'll also be able to turn off our over head lights, that way you can see it in a low light setting. So here you can see the light provides consistent signal and again this light is going to function as your clearance or side marker light. That's going to do it for today's review of part #MCL67RB. This is the Optronics Thin Line LED Clearance or Side-marker Light.

Absolutely excellent replacement parts, received on time and in perfect shape. Replaced all the lights (clearance, fender, turn signals, stop, and utility) with much brighter leds. Took about 1 hr to clean up all the contact points and test eveything. Extremely pleased with 'like-new' lighting system! Will send photos by email... 291071

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

Great price and worked good. Wished could have found the light cheaper without black adapter. Rest of trailer is gray. 321995


Comments

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!

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


Comments

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

These were the exact fit for my 2003 Haulmark, trailer, the price was equal to Haulmark,, shipping was 2.99 (USPS) HM only had 15.99 (USPS) the 2 lights are under 6 bucks This is the place for trailer parts. I will take time to check out the entire website. 572476

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
