Optronics MCL57 Series 2.5 In Round Sumbersible LED Clearance or Side Marker Light - Red Lens - 3 LEDs Diagram

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.


PL-2 Wiring Connection

Optronics PL-2 Connection

This light has an industry-standard PL-2 connection as pictured above. The light accepts a 2-prong plug (sold separately). The plug connects to 2 of the points on the PL-2 connection for power and ground. And the plug covers the unused third point on the connection to seal it against dirt and moisture.


Recessed-Mount Light

Recessed mount light

Recessed-mount trailer lights install underneath a housing or a grommet, which is often sold separately. These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Video Transcript for Optronics LED Red Trailer Clearance and Side Marker Light Installation

Today on our equipment trailer, we'll be installing the Optronics LED trailer clearance and side marker light in a 2-1/2-inch round design in red color, part number MCL57RB, and we will also be installing the Optronics 2-1/2-inch round grommet for flush-mount lights, part number A55GB. Now, we're first going to need to remove the existing light. This existing one is actually an incandescent style bulb, and we're switching this trailer over to all LEDs. We'll first need to go ahead and pry the old light out of the rubber boot. To do that, we'll just use a flathead screwdriver and kind of work it around. Then, we'll need to unplug the 2-prong plug at the backside. Now, since this rubber grommet is a little torn up, we're going to go ahead and replace that as well. Now, you'll notice that there's a lip here, and this right here is what actually catches on the edge of the trailer here, so to install this, we'll go ahead and work it down in there like that.

You can see how the lip kind of pushes upward. You just have to keep working it all the way around to make sure that the edge of the lip slides into the groove all the way around on your grommet. Now to make the new light slide in a little bit easier, we found that if you take just a little bit of grease and just smear it around the edge right here, it'll make the light slide in a whole lot easier on this new grommet. Here's our new 2-1/2-inch red LED side marker clearance light. You'll notice it has a 2-prong design on the back again, so it's essentially exactly the same dimensions and everything that the incandescent bulb we just took was, but this one is LED, uses a lot less draw, and the light will last a lot longer. To install it, we'll just go ahead and take our plug. We'll need to plug these all the way in. You'll kind of feel them click into position.

That means that the plug is fully seated in the light. Now that we've got our plug in the backside of the light, before we actually put it back into the grommet, it's a good idea to test it and make sure that it's working fine. Now that we've tested it, we know that the light is working fine, we'll go ahead and put it on into the grommet. To do this, you'll just simply work it in along the edge, and by adding that grease that we did earlier, it makes the light slide into the grommet a lot easier. Now we have our light pushed all the way into the grommet, go ahead and just take a paper towel and wipe off any excess grease that may be on the grommet or on the light itself. Once it's pushed back in, we'll go ahead and test it one more time to make sure everything is good. That's all there is to it to installing the Optronics LED trailer clearance and side marker light in a 2-1/2-inch round design in red color, part number MCL57RB. .

Good lights, work well and easy to install. Would give 4 stars but one of them arrived with a chipped housing. Hoping it will be okay because it's behind the grommet so shouldn't see much water. 550612

Do you have a question about this Trailer Light?


  • Replacement Clearance Lights for a 1977 Rancho El Rae Camping Trailer
  • Unfortunately even with the mounting dimension it will be difficult for me to recommend a replacement lense cover for a trailer that old without knowing the brand and model number of the lights you have installed. Therefore, I recommend replacing the lights on your trailer with a set of new LED lights that way you will not have to worry about them for some time. For the circular lights on your trailer I recommend using the LED Trailer Clearance/Side Marker Light part # MCL57RB for red...

  • Recommended Clearance Light And Grommet For Older Snowmobile Trailer Rebuild
  • The clearance light I recommend for your snowmobile trailer is part # MCL57RB. This is a 3 diode 2-1/2 inch round light. It does require a rubber grommet for installation. The grommet to use for installing this light I recommend is part # A57GB. You may need to take a small round file and open the mounting hole you said measured about 2-5/8 inches but this should work well for your trailer. To connect the light to your trailer wiring I recommend using the Two Wire Pigtail, part...

  • Availability of a 2 Inch Diameter LED Trailer Light
  • We currently don't stock a 2 inch that is 11/16 inch deep. The closest we have are two and a half inch and 11/16 inch deep LED red lights: # MCL59RB # MCL57RB Another very close option would be Optronics GloLight LED # MCL155RB. It's 2 inch diameter and 3/4 inch deep. You may need # A46PB two wire pigtail for sealed trailer clearance, side marker lights.
