Optronics MCL50 Series Miro-Flex Red 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 Round LED Trailer Side Marker and Clearance Light Installation

Speaker: Today on this trailer we're going to install Part No. MCL50RB from Optronics. First thing we do, is go ahead an remove the existing light. We'll spray it down with some lubricant and then pry it out around the edge. Once we have the light loosened up we'll go ahead and pry out the electrical connector and then we'll go ahead and spray it and ground it down with a little more lubricant. We'll go ahead an take our new electrical connector and plug in to the back of the light. We'll go ahead and push it down into place. Make sure it's a tight fit and then work the light back into place. Now we'll go ahead and apply some power. We have our new LED light along with an incandescent for comparison. Our install of our new light is complete. There you have it for Part No. MCL50RB.

I bought a set last year form another distributor and were to be watertight. The ones I bought from etrailer states waterproof and they are going on a boat trailer. We will see how well they work once I launch the boat and see if any water penetrated the inside of the light. 423798

I ordered a 2" LED clearance light for my 5th wheel because I could not find a suitable replacement locally. The service was excellent and the product better quality than the original. etrailer.com will be the first place I go in the future! 195150

by:

I rated "good" only because of my application. I had 6 of these on back of my 1 ton flatbed 3 high and 3 low and for what I needed they where too bright. Working around the truck at night was blinding. They certainly would make a trailer visible. I went with the 4 Diode and they were PERFECT.. 189191

Outstanding! I didn't use the product for it's intended purpose, but rather as a "third eye" stop light for my Jeep. Works perfect! Just what I wanted. I'm very glad I stepped up and purchased the pigtail and grommet. Without these two extra items, my project would have failed. 155888

I will be using thiese products on a trailer I am refurbishing to pull behind my trike. The only drawback I have noticed is that I wish the black grommets came with a touch a chrome, to dress up the application. 71011

Hello Ken - we do have a 2 round chrome trim ring for the grommet mount lights. The part is A55CB, and they would look great being pulled behind your trike!

This little light is very bright and makes a great clearance light. Not like any incandesent light, when one element goes out, the rest of them still burn. 44661



- MCL50RB
by:

Overall good light, but it's about 1/2 inch thicker than a standard side marker and therefore sticks out from the rubber housing further. 29742

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 112392

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 Optronics Miro-Flex in Trailer Lights


These are perfect for my hard used-utility trailer. I haul a huge amount of firewood, gravel, top soil, lawn mowers, and rocks and the old tail light bulbs were constantly burning out. The new LED lights were super- easy to install, fit perfectly, and are much brighter than the old. I wish I would have installed these lights years ago. Highly recommended! 569978

Do you have a question about this Trailer Light?


  • Polarity of Optronics Sealed Micro-Flex LED Trailer Side Marker # MCL50RB
  • The Optronics Sealed Micro-Flex LED Trailer Side Marker # MCL50RB referenced in your question does have polarity, but the PL-10 Plug # A46PB that you also have is designed so that it can only be plugged in one way. This is essentially how you will know which way to plug the harness into the light. Since LEDs use diodes, if you were to somehow connect the harness backwards, the light simply would not work and you would just need to turn it around and plug it back in. On the harness itself,...

  • Will the Miro-Flex, 2 Inch Round, LED Trailer Light, # MCL50RB, Fit an Enclosed Snowmobile Trailer
  • If adding the Optronics light, # MCL50RB, you will need about 2 inches of space behind your existing light for it to fit. The reason is the Optronics light is deeper including the pigtail mounting surface and the pigtail, # A86PB. If you have at least 2 inches of clearance, then this light will fit in your existing 2 inch diameter hole with grommet # A54GB. Light # MCL55RB is not quite as deep at 1 inch overall, so that is another option for you.

  • Will 2 Inch Diameter Lamps Fit into Circular Cut Outs in Sides of Rola # 59502 Cargo Carrier
  • The grommets for 2-1/2 inch lamps are a bit too big to fit into a 2-1/2 inch rough opening. The # A56GB grommet for instance, is meant to mount in a 2-3/4 inch rough opening. If you could enlarge the opening to 2-3/4 inches in diameter, then a 2-1/2 inch lamp like # MCL50RB would fit. If you decided to go this route, you'd tie the power for the lamps into the running lamp circuit. A # A46PB pigtail would be needed for each lamp.
