Optronics MCL51 Series 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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL51RB Review

Today we're going to be taking a look at part number MCL51RB this is Obtronix sealed neuro flex 2 and a half inch round LED side marker clearance for identification light. It's going to have the red lens as well as the red LEDs. It's going to e a 3-dio design, so it's going to contain 3 LED's. LED's are going to be great replacements for incandescent lights, you don't have to worry about replacing the bulbs, you don't have to worry about regular filaments. They're going to burn brighter, last longer, and they're going to be much more efficient. This is going to feature a sealed waterproof lens and housing unit. It is a grommet mount, the grommet is going to be sold separately.

Then here on the backside it's going to have the nice white housing as well as a two prong connection plug. Or a two prong connection point so this is designed to accept the industry standard two prong plug, and again that is going to be sold separately. The diameter of the light, here at the back, edge to edge is going to give us a measurement of about 2 and a half inches. We take a measurement of the depth, it's about 1 and 3 16ths of an inch. Diameter here at the front is going to be about 2 and a quarter. This features the neuro flex technology so it's going to increase your light output while using 90% less energy when compared to most incandescent bulbs.

Has a really nice contemporary appearance and the LED system is going to draw 0.033 amps at 12.8 volts. It is department of transportation and SAE approved. Electronics is going to put a lifetime warranty on the LEDs. We offer multiple grommets to chose from when you are ready to install this. If you don't already have a grommet you can check out the related items on this products product page right here at etrailer.com. We're going to go and hook this up to our external power source.

That way you can see what it looks like with power running to it. We're going to take our two prong plug, place it into the connection points here on the back, and then give it a nice push until we get it seated correctly. You can see here that the lights have got a really nice consistent signal. Again, it's going to contain 3 LEDs so the multi dio design is really going to optimize our light output. Allowing us to have a really nice, clear, consistent and bright LED signal. That's going to do it for our review of part number MCL51RB. This is the Obronix sealed neuro flex 2 and a half inch round red LED trailer light.

Review from a similar Miro-Flex in Trailer Lights


This fixture was the exact replacement for my 2011 Trailmanor 2720 trailer. The manufacturer had moved to a more modern looking fixture. I was even able to use the old chrome piece from the old fixture to keep a uniform age look. I installed a wireless rearview camera and needed a new fixture and its longer wires to make everything work. May look a little strange, but it works like a charm. E-Trailer service was excellent as usual.


Comments
The fixture is still hanging in there. No issues.

Review from a similar Miro-Flex in Trailer Lights


I installed these lights in a [email protected] teardrop camping trailer. The grommet would not work on this style trailer so I installed the lights using a silicone adhesive the same as the original Peterson lights. eTrailer delivered them in the same timely manner I have come to expect from them and the LEDs were easy to install. These lights are blindingly bright - simply amazing. I had rear lights with 1157 bulbs which I had upgraded to 2357 bulbs and equipped the tow vehicle with a powered converter but the light output was dim by today's standards. These lights are twice as bright on running lights and about 4 times brighter on the brake/turn signal elements. The thing we all fear when towing is being hit from behind by a driver that does not see our running, brake or turn signal lights in time. I know these lights will vastly improve the safety and visibility of our trailer. Thanks!


Comments
These lights are great and you have sold a number of them to our friends now.

Review from a similar Miro-Flex in Trailer Lights


These side markers (both red and amber LED) are great for my 12' trailer. They have 3 LEDs (you can also get 4), and their size is perfect for a small trailer. The LED's are really bright, not only at night, but also during the day, so they are easily seen. I especially like the fact that they are sealed, so there should be no water intrusion problems in the future. I have included a few pictures, the first showing the round LED brake/turn/running/reverse lights (that I had purchased earlier from etrailer) with the red side marker mounted vertically on the outside. The second shows a side view of the red side marker light, and the 3rd picture shows the side marker mounted to a small piece of 1" X 1" x 1/8" aluminum angle which I painted black to match the mounting frame of the round LED lights. I mounted the LED side marker to one leg of the aluminum angle, then mounted the other leg with 1" standoffs to two holes already present on the black mounting frame of the round LED light. Although all the lights are sealed against water intrusion, I decided to mount them on each side of the trailer at the top of 2 PVC pipes, about 36" long each, where the lights would not be exposed to immersing in water when launching/retrieving a boat.


Comments
After a year, the lights are still bright as ever. One of them even survived being drug down the highway for 100 yards when the PVC pole it was mounted to came out of its holding fixture!!

Review from a similar Miro-Flex in Trailer Lights


These are a perfect upgrade on my jet ski trailer which was constantly burning bulbs maybe because the lights were not watertight. No amount of dielectric grease prevented it. These were easy to install. They are watertight and are twice as bright as the old ones. Great customer service! I highly recommend the lights and etrailer.com!


Comments
They are still working well and could not be happier. They are bright and a perfect upgrade. I had the marker lights go out briefly but only due to a dirty ground. Other than that, perfection! Thanks for following up! That’s ideal customer service.

I put these on the side of a 39 foot travel trailer mostly for the people next to me while towing. They are bright and useful. I do not care for the fact that they light up when the brakes are applied. Other than that they are all good.

I ordered a cheaper version of these lights and they lasted two trips down the boat ramp. I decided to up grade to these higher quality lights for my boat trailer and I have had only great results with no problems. They are water proof and highly visible in the day and night time. Get you a set you will not regret your purchase.


Comments
GREAT Ive had no problem with these lights. They have been in the water hundreds of times and are still in great shape.

Review from a similar Miro-Flex in Trailer Lights


I received the lights and tested them; they worked fine. They are destined to be used on a car, not a trailer. Side marker lights for cars/trucks are rare now because they are incorporated into the front and rear light assemblies and rap around the vehicle. The lights I ordered from you are the only ones I could find that had a hole-mount pattern wide enough to clear the metal cutouts, under the old lights, in the fenders of my car. I'm glad you have a huge selection to choose from. I'm not sure when I'll get around to installing them. The car is undergoing a restoration for the third time. All I know is the next time I remove the stock side markers, they will shatter. Few trim parts are available for this car these days and nylon snap-in mounting tabs dry rot and break after a couple of decades. I bought this little car new 26 years ago and took it around the world with me before I retired from the Air Force. I attached a picture of it from the last touchups 7 years ago. It won't quit running so I keep giving it new birthdays. This little rat car has become a part of my DNA. 1991 GEO Tracker 4x4. Original owner.

This product worked great replacing my old dry rotted, screw stripped bulb tail lights(approximately 5"x5.5") on my boat trailer. In fact, they fit in the tail light mount better than the old light. The installation couldn't have been any easier. Special thanks to Cailee V for getting me setup with these tail lights after I ordered a different tail light on my own that didnt work for my project.

Review from a similar Miro-Flex in Trailer Lights


When I trailer I typically launch in salt water at the Jersey Shore. These lights have held up well in the last year. These lights are a huge improvement over the standard trailer lights that start rusting almost immediately. E Trailer is my go to when I need trailer parts.

Review from a similar Miro-Flex in Trailer Lights


These lights are of very good quality and are really bright. I use them on an early 70's Bronco for the front turn signals. Day or night, they are distinct and unique and best of all, . Definitely visibly on during the night AND the day (this can be seen in the photo taken on a Snow day, bright, while half way out of my garage). Great price for a great product


Comments
The LED lights are great. Im very satisfied with them. They have held up well and work like a charm with a distinct look to them as well.

Review from a similar Miro-Flex in Trailer Lights


Bought these to replace all of the single wire, ground to the trailer type lights that were on my boat trailer. I bought the amber, red and white lights for the various positions I needed them in. They are bright and work very well. For mounting hardware, an 8-32 machine screw fits just right. Something to be aware of, they say it’s a flush mount, but it’s not with the wires sticking out the back of the light. Instead of drilling a relief in my trailer, I opted to use some aluminum cable stops as standoffs. See pictures to further explain. Worked great in the end. These are quite bright for marker lights and and perfect for what I wanted. ETrailer has prompt shipping as usual.

Super fast shipping! Ordered on Saturday with etrailer's free shipping option and received my order on Tuesday. Thanks! The lights appear to be of high quality. Comes with all necessary hardware, but I used butt connectors instead of the supplied come shaped connectors. Lights are MUCH brighter than the halogen models they replaced; both tail and brake/turn. You could barely see the old taillights in the day time, these are far superior!

Review from a similar Miro-Flex in Trailer Lights


Definitely a major upgrade from the single bulbs that finally went out on my old trailer. Simple as can be when it comes to install them. I did have to run additional ground wires to get to get lights to work when the parking lights are on. Could have been due to the fact my trailer is a tilt trailer? No big deal just a heads up if anyone else is having the same problem. Pictures shows them with parking lights on and brake lights. They're bright that's for sure!

I like the light, I just wish you prompted me to buy the grommet which is why i deducted a star. I had to place a second order and now I have to wait again to install. Overall it was a good experience. Would have been perfect if I was promoted though


Comments
I apologize for the confusion. The grommets you are referring to are located in the related parts tab on the product description, item #A91GB.

Review from a similar Miro-Flex in Trailer Lights


Great little lights, and very bright as well. They have been installed on a trailer and submerged many times since installed, and still work great!! Can't beat LED's for brightness and, hopefully, longevity!!! Attached is one picture of the overall trailer, and a closeup of the amber side light. I also have 2 red sidelights that are mounted above water at the rear of the trailer, and they are still working great as well.


Comments
These side lights are bright LEDs and the amber ones have been submerged more than once-and are still working great!! The red side lights are mounted high on the vertical poles, so do not get submerged in water. However, all 4 side lights have been exposed to the weather for over a year, and all are still burning bright!! These are cool little LED lights!!

Nice lights once you get them installed-They are bright and look nice on the 1970 Sears boat trailer. The wires that come out the back need a 3/4" hole to fit through-so I had to drill a 3/4" hole in the trailer plus the 2 mounting screws holes. I had as much $ in drill bits as I did with the lights
