Optronics MCL36 Series Stud Mount Side Marker and Clearance Light Diagram

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 - MCL36AB Review

Today we're gonna be taking a look at the Optronics square LED trailer light. This amber square light functions as a clearance and side-marker light. It does feature a reflectorized lens, that's DoT compliant, that's Department of Transportation compliant, which eliminates the need for separate reflector. The unit's got a feature a nice weather and corrosion-resistant design. It does feature a replaceable lens. That lens is amber. It's held on there with two screws.

This light contains a total of six LEDs. LEDs are great replacements for incandescent lights. They last longer, they burn brighter and they're much more efficient. You don't have to worry about replacing bulbs or worry about brittle filaments. The unit's a two-wire design so your white wire with a ring terminal on there, that's your ground wire. Your black wire's your power wire.

It's a stud mount installation and it's gonna come with the mounting nut. That stud measure five-eighths of an inch long. Taking a look at the dimensions of the light itself, starting with the overall length, going edge-to-edge this direction. You can see that's gonna measure about two and seven-eighths of an inch. Going in this direction we're looking at about two and one-eighth of an inch. And then the thickness of just the housing, that's gonna measure about one, almost one inch, maybe 15-16ths of an inch right in that area. When it comes to the power draw, at 12.8 volts, it's gonna be 0.054 amps.

We're gonna go and hook it up to power, that way you can see what it looks like with some power running to it we'll also be able to turn off our overhead lights so you can see it in a low-light setting. So you can see here that it sends out a nice clear, consistent signal. Again it's gonna contain a total of 6 diodes or LEDs. The multi-diode design really helps optimize the light output, and again this light's going to function as a clearance and side-marker light and it does have that nice reflectorized lens that is Department of Transportation compliant. That's gonna do it for today's look at the Optronics square LED trailer light.

6 LED marker lights perfect upgrade for my 2004 utility trailer replacing factory incandescent bulbs. Much easier to see trailer when pulling and backing at night. Much safer for others to quickly spot my trailer in bad weather conditions... much BRIGHTER ! Unlike others manufacturers, there is more than enough wire to allow easy soldering along with a ring terminal which guarantees a perfect ground to trailer. Always quick shipping etrailer.com my go to online store 582427

Working great. Very happy with etrailer! Really appreciate the hands on videos demonstrating the products and the "how to" videos. Very helpful! 562933



- MCL36AB
by:

This is a nice quality light and the LED aspect of it is sweet. I am holding back a star because the black wire that powers the light is ridiculously short. If you are running the light out on a fender, you have to split your wire harness and send the brown wire to it. If the manufacturer had spent another one tenth of a cent and made the black wire longer, it would have been better. Also, the back of the light, the grooves for the wire are a bit shallow. Difficult to get the light to sit properly. Once it's up and running it's quite sharp. 561225

Used 2 of these on my '34 Ford 3-Window Coupe as a front turn signal lights. I have cut out slots in my fenders and mounted these from behind for a "Frenched In" look. Work great!! Looks COOL!! 557546

Excellent products. These lights work perfectly, are rugged and seem to last. The license plate lights are super bright so law enforcement have no problem reading the plate which avoids unnecessary stops. The lights are directs replacements as well so no modifications needed. Great products. I recommend etrailer to many of my friends and colleagues. 546256



- MCL36AB
by:

Excellent packaging and shipping. Nice lights, simple install to replace damaged lights. I prefer internal grounding through the stud, the exposed wire will eventually corrode in road salt. Longer lead wires would be better, the 4 inch wire leaves the splice right behind the light rather than hidden in the frame like the original light. I installed with heat shrink tubing and split loom for protection. Bright lights, easy installation. 541863

Replaced all of the lights on my utility trailer, whose incondescent bulbs were constantly breaking, with LED lights and fixtures. The LED lights are bright and dependable. The onboard computer senses when the trailer is attached and works fine with the LEDs. I'm very pleased that I made this switch and with the parts provided by etrailer.com. Good quality parts at reasonable prices. 467257

Needed new marker lights for a utility trailer. These are an exact replacement. I connected the white lead (ground/negative) to the mounting stud. LEDs provide good light for visibility and reflectors are bright. I liked them so much that I ordered a second pair for another trailer. 435280

2nd pruchase from them, Bought the 3 red LED lower trailer bar and its great. Now bought two side LED yellow running lights and a large orange LED light that mounts up by the winch. I have not installed them yet but since they are like the bar light I know they will be very bright and easy to install. Good customer service from etrailer. Boat trailer is now fully LED lit 432420

Reworking my Pacwest Trailer and these are the original equipment replacement, only new LED. Much brighter, less draw and look sharp. Even bought a couple of extras. 424281

Using these as side marker lights on my jetski trailer. The old light used the mounting stud for ground, these lights have a separate ground wire with a ring terminal on it. No problem, just had to drill a hole to screw the ring terminal to the trailer frame. Lights are bright. I took the lens cover off, the LEDs and circuit board are potted to prevent water from corroding them. So these lights should survive dunking in the lake/river/ocean. 420306

Do you have a question about this Trailer Light?


  • Recommended Red Square LED Trailer Clearance Light
  • For your boat trailer, you will just need the Optronics LED Trailer Clearance, SIde Marker Light with Reflector - Red # MCL36RB. This is the exact size and design as the Amber # MCL36AB that you referenced and will mount using the included 5/8 inch stud. This is a very nice, square LED clearance light that measures 2-7/8 inches long, 2-1/8 inches wide and 15/16 inches deep. I have attached a short video demonstration on this product that you can also check out.

  • Availability of Optronics LED Trailer Clearance Lamp # MCL71RB in Amber
  • The closest thing we have to the # MCL71RB in amber would be the Optronics # MCL36AB, which is also available in red as part # MCL36RB. The lamps are a bit smaller than the # MCL71RB at 2-7/8 by 2-1/8 inches. Optronics doesn't offer that lamp in amber as an LED version.

  • How To Ground Trailer Tail Lights Without a Ground Wire To a Wooden Surface
  • The Standard Trailer Light Kit with 25' Wire Harness part # TL29BK as I am sure you noticed grounds via the mounting hardware therefore there is not a singular ground wire. In order to attach this light to a wooden surface you will need to run a ground wire yourself up to the trailer tongue using the mounting studs on the back with ring terminals part # DW05705-1 and wire part # 12-1-1. The other option you have is to use the Peterson LED Light Kit for Trailers part # V944 which does...

  • Armored LED Clearance Light # 424000 Recommendation for a 2007 Jumping Jack Trailer
  • The reason some lights have two wires and others only have one wire is because some lights ground through the mounting studs (one wire lights) while other lights have two wires, a power wire and a ground wire. If your old lights were one wire lights and you wanted to use a Square LED Trailer Clearance, part # MCL36AB, you could run the ground wire to the mounting stud for the light and you would be good to go. We do not sell rock guards for the # MCL36AB, but we do sell armored clearance...

  • Replacement Incandescent Side Marker Light for Trailer

  • Can Clearance Light with Black and White Wires Replace Light with 2 Green/Brown Wires
  • Yes, the replacement light will still work. Although there are common colors for the wiring on a trailer, nothing is set in stone so the colors of the wiring can vary. Just be sure to ground the white wire of the Optronics Square LED Trailer Clearance Light # MCL36AB to a clean, bare-metal surface to avoid shorts on your light circuit.

  • Are Mounting Brackets Available for Optronics Mini LED Clearance Lights # MCL95AB and # MCL95RB
  • The Optronics Mini Rectangular LED Clearance Lights, # MCL95AB and # MCL95RB, are single stud surface mount lights, so they do not have a grommet or mounting bracket available. They were designed to mount directly to an existing bracket or to the trailer frame. The closest clearance lights that we carry to the dimensions of your current lights are the Optronics Square LED Clearance Light, # MCL36AB and # MCL36RB. These are also single stud surface mount lights, but the larger size should...

  • How Do I Convert My Incandescent Trailer Lights to LED Lights
  • Yes, you just have to remove the old lights, match the wires and mount the new ones. Please note, that it is usually not a good idea to mix LEDs and incandescent lights, so if you have have side markers or other lights on the trailer, make sure you switch those to LEDs as well. Incandescent lights draw much more amperage than LEDs do, and if they pull that current through the LED fixtures, the LEDs could burn up. We have LED side markers and clearance lights like part # MCL36AB and...

  • Is the Ground Wire Needed for the Square LED Trailer Clearance and Side Marker Light to Work
  • Yes, the second wire will need to be grounded to complete the circuit for the LED Clearance Light, # MCL36AB. If your trailer connector has a ground wire that is connected to the trailer frame at the front of the trailer, you will be able to just secure the ring terminal on the LED trailer clearance light, # MCL36AB, to the trailer frame with the light mounting bolt or a self tapping screw (not included).

  • Tracking Down Possible Trailer Ground Problem to Repair Running Lights
  • As a first step, you will want determine if the wiring problem is on the tow vehicle or the trailer. You can begin by using a circuit tester like part # 40376 to test the trailer connector on the tow vehicle while a helper activates each function. If you get no signal on the pin that feeds the running lamp circuit, you know the problem lies with the tow vehicle. If this is the case, you will need to check fuses or the wiring connections of the trailer connector. Also, check the connector...

  • Troubleshooting Trailer Lighting Where Only One Running Light Works
  • Since all of your trailer lights operate properly with the exception of one of the running lights, this tells us that the vehicle wiring harness is probably working properly. I would first carefully check the bad light's ground and power wires to ensure that both are secured. If the light uses a separate ground wire, usually a white wire like on # MCL36AB, that ground wire needs to be affixed to the trailer frame, to a clean rust-free bare metal surface. If the light is the type that...

  • LED Trailer Lights Not Working
  • Thanks for your recent purchase! This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached...

  • Not Getting Turn Signal Function When Using LED Bulbs On A Trailer
  • LED bulbs have little resistance on their own, so when used with turn signals they can create a hyper flash situation, which is a fast flashing of the bulb. To determine if you will need a load-resistor kit like the Putco LED Light Bulb Load-Resistor Kit - Ceramic, # P230004C, you will install the bulbs and when the turn signals are activated, if the bulbs hyper flash you will need to install the load-resistor kit. This kit will prevent the turn signals from hyper flashing. You will need...
