Optronics MCL65 Series LED Fender Light with Bracket 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.

They work well. Replaced all my incandescent lights on trailer. Thank you.


These lights are definitely the best I could find for my applications, they are water prove, large, bright, and well designed. I replaced my boat trailer and dump trailer lights with those. If they damaged I don't need to unbolt them, just pull the light of the base and push a new one in. Excellent product and great customer service.

Those lights are bright, have were submerged in salt water at least 50 times and never shown any problems. Excellent product.
Walter K - 09/13/2018


These fender lights offer very good vis ibility.


Really good lights, would be nice if a curved base option was available for curved wheel fenders. Needed to add shims to keep light base from bending

Still working just fine - no issues
Barry D - 06/17/2020


A great replacement light for the original and I'm very happy with the LED design.


i got what i needed but it took a week before it got out of your door. it was only two fender lights.


Exact replacement


Your company seemed to be the only one to have this particular light.Ordering was easy and arrived on the date promised.Thank you


Fast and complete


thank you for all the help. Love the se rvice.


I purchased several lights and one round yellow clearance light has failed. I have not seen a vendor that made me pay to ship their failed product back. Unbelievable. The lights can be purchased from [online store] with no hassle returns


These lights worked great, were simple to install and are much brighter than the ones I replaced.


Perfect replacement


really lights up trailer corners for visibility at night.


Exact match for the lights on my traile r.


GreT products, in stock,delivered fast !


Product worked great. I have a 2013 Aluma trailer. The fender lights both broke off. When i called for replacement lights from Aluma, i got the run around and was finally told that 2 lights were $80 shipping included. I just about fell over. So, i took a risk and bought 2 of these. Great thing too because they were an exact match for way less AND the base was improved over that of Aluma. Easy install and everything.

Product continues to work great with no defects. Lights are still as bright as day 1.
Robert M - 10/21/2018


Bought this product previously and it has served well on my first trailer.

My trailer is highly visible, just the way I like it.
Tom - 10/26/2021


The products are just what I needed. I was particularly impressed with the order processing and the tracking with its use of maps to indicate the location of the package with the tracking information. I have never seen tracking enhanced to this level before. This is a company I definitely buy from again!

The product is working just fine and I will order additional items from this company when I need them.
Stephen - 06/15/2019


Top quality- perfect replacement for previous lights. They were simple to install and work as designed. These lights are much more visible than previous, yet similar, lights. The best part of this purchase is the top-notch customer service at!

Not even a flicker. They work perfectly.
Doug S - 06/09/2015


Light is working good and is exactly what I ordered.


Great, fast and accurate service and delivery of a quality product! Thank you!


The LED light was exactly the model I needed. I have the same light but a few of the LED's had stopped working. The nice thing about this light is that it's a plug and play part. Just unplug the old light and plug in the new one.

The LED light is still working perfectly although I will say that I do not use the trailer its on all that much
Kevin M - 06/20/2018


Initially I didn't think I'd like these mid ship lights. The old ones were tapered down on the leading and trailing side of the lens so you could see them forward and back very well. As soon as i turned them on that concern was gone. There are 2 (or 4-can't recall right now) led's facing forward and back plus the row of led's facing staight out so they are very bright at all angles of viewing. I've bought enough overpriced junk led's in the past to know a quality light when i see one. All of the led's purchased from etrailer are top quality, completely sealed units. My only complaint was the packaging (and I'm not the only customer that complained). I hope etrailer has addressed that issue as i plan on purchasing all of my future trailer parts from them. This purchase was part of a complete restoration of a 1999 21'x8' Cherokee enclosed trailer.


Timely delivery with great customer ser vice!

    The bracket of the Optronics Thinline LED Trailer Fender Light w/ Bracket # MCL67ARB has mounting holes that are 3/16" in diameter; the mounting holes are also 3" apart on center. I have added a couple of video reviews of this light and bracket for you to take a look at.

  • Replacement Rectangular LED Light Combination Amber/Red
    I have a couple options for you that are going to be a close match to the Peterson Piranha LED Clearance Light # M161R . # MCL65ARB is 3-15/16" long and a 10 diode LED light that is amber on the left and red on the right. This is a surface mount light and does not come with a mounting bracket. # MCL67ARB is the same light that comes with a mounting bracket included. If you were looking for a 2 diode light you can use # MCL61ARB which does not come with a mounting bracket. If you're looking...

  • How Does the Bracket # A67CB and Clearance Light # MCL67ARB Wire to Trailer
    The reason the # A67CB bracket uses a single wire is because the light will ground through the mounting hardware. If you needed to run a second ground wire to the assembly you would only need to run the stripped ground wire around the mounting screw that attaches to the side of the base with the ground strap. See picture I attached to see which side has the ground strap. The # MCL67ARB uses a similar setup and also grounds through the mounting hardware. The single wire coming from the...

  • Availability Of Optronics MCL61AR26BK Amber/Red Fender Light
    I have a complete replacement option for you, but just the lens portion of your light is not available by itself. Based on the model number on the rear of your light you will need the Optronics Thinline LED Trailer Fender Light - Submersible # OPT36FR which will be an exact replacement. With this you can reuse your current base, and just keep the new base on hand in case you need it in the future. I included a video of the # OPT36FR for you to take a look at.

  • Recommended LED Clearance Light that is Red and Amber
    The Optronics LED clearance light that is similar to # MC65RB, but will be amber and red, is the Optronics LED clearance light # MCL65ARB. This light is sealed, waterproof and is a surface mount. The dimensions are 3-15/16 inch length by 1-1/4 inch width by 7/8 inch deep. You will need a bracket and plug like # A65PB to complete the installation of the Optronics LED trailer light # MCL65ARB.

  • How To Install the Optronics Thinline LED Trailer Fender Light
    The Optronics Thinline LED Trailer Fender Light part # MCL67ARB comes with a mounting bracket so as long as the surface you will be installing it on is metal then yes, it will work for you. All you would need to do to install the light is use two self tapping screws like part # 1131832 to mount the base and then once this is done you can attach the light to the base. To complete the process you will then need to attach the black wire to the running light circuit on your trailer which is...

  • How to Connect a Clearance Light with a Single Wire to a Trailer with Two Wires
    You can definitely wire a clearance light with a single wire to a trailer that has two wires. The first thing to know is that the two wires from the trailer are not positive and negative. Rather, they are the running light wire and the grounding wire. The running light wire (usually brown or black, but sometimes another color) is the wire that you connect to the wire coming from the light. To do this, use a butt connector like part # DW05744-5. The ground wire (usually white) from your...

  • Replacement Optronics Fender-Mount Red/Amber Tail/Clearance Light for Charmac Cargo Trailer
    I reviewed quite a few photos of various Charmac cargo trailers and while I found some with external fenders I did not find any shown with lights installed. However, we do offer a lot of combination red/amber trailer lights and all are shown on the page I linked for you. Among these are fender-mount lights # MCL67ARB, # MCL12ARLB, # BA44FNR and # BA44FNL. There are others too on the linked page. If none of these is a correct replacement you can submit a photo .

  • Recommendations For Adding LED Marker Lights To A 20 Foot Cargo Mate Trailer
    You are correct. Red lights should always be as close to the rear of the trailer as possible. With that also said, if you wanted to use something like the Optronics Thinline LED Trailer Fender Light w/ Bracket # MCL67ARB on the fender, you will want the red light pointed towards the rear of the trailer and the amber light pointed towards the front of the trailer. If you do not already have the lights picked out, the Optronics Thinline LED Clearance and Side Marker Light # AL91RB (Red)...
