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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL65RB Review

Here we have Optronics sealed, thin line LED trailer clearance and side marker light, part number MCL65RB. The lens of this light is sealed and waterproofed to the housing. Inside are 6 LEDs that draw a total of 0.048 amps at 12.8 volts. It is designed to be used with a mounting bracket to complete the ground connection and a single pole wire lead to complete the power connection. Next we will hook the light up to a power supply so you can see how it looks. We will connect the ground connection to one of the posts and our power to the other. Next we will turn off the overhead lights so you can see how bright the light is. And that does it for Optronics sealed, thin line trailer LED clearance light, part number MCL65RB.

Bought these lights to replace on our horse trailer. They work great, easy to install and look better than the original lights we replaced. Would buy these lights again and would recommend. 666349

Quality product! The LEDs light up brightly. They're brighter than i expected! I bought enough to change out all my trailer lights, it worked out well. So far they've been through some extreme weather. I've used the trailer in heavy rain, high heat, through winter and freezing temps, and many washes. They haven't leaked and lenses still look great. It's only been a year and I'm hoping these will last many many more. 639277

Comments

The MCL65RB lamp you purchased needs a mounting bracket like part A65PB in order to be installed. The bracket includes sockets that receive the pins on the back of the lamp. Because there are a number of mounting options and kinds of brackets available, the bracket isnt included with the lamp. If you take a look at the links below, you can see the available brackets that are compatible with this lamp.

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.

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

Review from a similar Optronics Thinline in Trailer Lights


I have a 2010 international trailer. I was unable to find exact match parts so I went to etrailer to find comparable parts. These 3 way tail lights were 5 inches longer, as posted in the description, than the ones that were on previously. I just drilled a new hole each for the wires and one screw and used one of the previous screw holes. These lights are bright and I was happy with the flush fit on the trailer. 662483

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!

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

I bought this light for the back of my Polaris RZR RS1 as a upper run / brake light in addition to the factory one. P I installed it and it works great!

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

Exactly what I needed. My old ones were 10+ years old and some of the LEDs had died. These thinline lights have more LEDs and they mount to a flat surface with two screws. The wiring colors matched my old lights and the installation was a breeze. I'd buy them again. 573957
