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.

Very pleased with everything



by:

Your service is outstanding. Thank you for shipping my light quickly.



by:

Good product. I 'm very happy with etrailers prices and service.



by:

Excellent web site. Really liked the pictures and video of the product. The shipping was super fast and complete.

Great Job!



by:

This light is a very bright clearance light. It will take the vibrations that a regular incandesent light will not take.



by:

Great product. Exactly as advertised. LED Lighting is well lit in darkness.



by:

Great running light!I replaced my running lights with these and they were a perfect fit and easy to install. This light should be much more reliable than an ordinary bulb unit and is plenty bright.



by:

Make sure you use these LED marker lights if you replace your tail lights with LED's



by:

Light was as discribed, delivered on time and appears to be a good quality light, we'll have to see how it holds up to Arizonas brutal sun. Installation was easy. Overall a good buying experience.



by:

These lights are awesome, I bought 2 and liked them so much, I bought 2 more! E-trailer is a pleasure to buy from, great communication and super fast shipping! Thanks guys!



by:

These side lights wired up quick and easy. I used 3M Scotchlok connectors to hook these into my running lights. Can't ask for much more.



by:

These lights are AWESOME! I decided to re-wire the flaky lights on my used trailer and these worked perfectly. They have the exact same mounting configuration as their incandescent counterparts (post mount) but draw much less current and are much brighter and never burn out.



by:

Quick delivery, easy install to replace old style incandescent ones that corroded and burnt out often. Side lights look reasonably bright. Tail & stop lights are well build and quite bright, especially the brake turn lights. They will get dunked in Baltimore's salty water this weekend for the first time. Looks like a nice upgrade, especially if they are not bothered by being immersed in the water.



by:

Put two on a trailer today. I wish bought more. Time will tell on the longevity. I do know the bulb types do not last unless you annually take them apart and clean them, and use dielectric grease to keep the corrosion at bay. Too much work all that. I think these will last a long time with no maintenance.



by:

The items ordered were exactly as advertised. The LED trailer lights were very bright, and as advertised. Best price on the net, and shipping was fast and free. I couldn't be happier with the order. All items installed perfectly.



by:

These look great on my trailer and increases the visibility over the old lights I had. Inexpensive, easy to put on and an easy way to add increased safety and value to your trailer.

Thanks for the input, glad you like them.


by:

My two year old yacht club trailer side marker lights had a mind of their own and would inadvertently decide to energize or not. The bulbs could not be replaced as these were a one piece unit.I ordered two LED marker lights from etrailer and after replacing the incandescent fixtures I haven't had an issue. I predict my rear lights being next.



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.



by:

Always look forward to getting parts from etrailer. Shipping is decent and parts are as described.



by:

Nice bright L.E.D. clearance lights.
Low
drain on your battery.
Works great on the golf cart I am refurbishing.



by:

Good product. Fast reliable shipping.

After one year of use all LED lights work flawlessly. They were an exact replacement for original. Can't be more pleased with the product and etrailer company!

Trailer is fully led from etrailer and still working flawless even after rough use. Great product!



by:

This is the expedition trailer you helped me build............Thanks.



by:

I got fed up with the bulbs losing contact in the stock clearance lights that came installed on my trailer. These were the solution. The LEDs should last a good long time and vibration won't be an issue. They are plenty bright enough as far as I'm concerned. As inexpensive as they are, they still seem to be fairly well made. A couple of self-drilling screws for the ground leads, a couple of crimp connectors and some heat shrink tubing for the power leads were all I needed to complete the swap. I'm totally satisfied. If these lights fit your application, buy them.

Still rock solid after a year installed.



by:

Installed this and several other lights on a new trailer. Factory lighting and wiring left a lot to be desired, and with the help of etrailer.com I was able to get everything fixed up like I wanted.

Lights work very well - clear and bright yellow clearance markers.

  • Replacement J-1024-A Side Marker Light
    Hey Larry! I checked with the manufacturer and the lens is not available for individual purchase but we do have a replacement for the side light. It's the Optronics LED Clearance or Side Marker Light w/ Reflex Reflector item # MCL36AB. This is an almost identical replacement except for the LED upgrade and it being an 1/8" wider. The replacement lens for it item # A36AB isn't going to fit your J-1024-A.

  • 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 a LED Light Bulb Load-Resistor Kit # DI34ZR, 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 one kit for each LED...

  • Parts Needed to Replace Lights and Rewire a 1993 Econoline Car Trailer
    To rewire your 1993 Econoline car trailer, I recommend using the LED Combination Tail Light Kit # TLL9RK. This kit will include the lights and wiring needed to rewire your trailer. The wiring will splice into your junction box. If you do not already have a junction box, you can pick up the Trailer Wiring Junction Box # 3375601101. Having a junction box makes dealing with the wiring on your trailer easier. If you already have or want to add clearance lights, I recommend the Optronics LED...

  • 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.

  • 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...

  • 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.

  • Replacement LED Taillights for 1999 ShoreLand'r Boat Trailer
    Looking at old pictures it appears as though your 1999 ShoreLand'r had rectangular lights like the Optronics LED Combination Trailer Tail Lights # TLL160RK. This includes the driver and passenger side lights. These are sealed and submersible so they're perfect for your boat trailer. They measure 8-1/16" long x 2-7/8" tall x 2-13/16" deep which I believe will fit nicely on your existing bracket. If you have other LED lights on the trailer you will want to swap those out as well so you don't...

    The Optronics LED Clearance or Side Marker Light # MCL36AB is not submersible. The Peterson Piranha LED Clearance or Side Marker Light # M170A is going to be the closest light we have to the same dimensions which is going to be submersible.

  • 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...

  • Why Does Ground Wire Corrode on Aluminum Trailer
    Thank you for the photo and what is causing the ground wire is the aluminum trailer; it's called galvanic corrosion and is an unfortunate side effect of having an aluminum trailer. This happening once every 18 months or so sounds about right and the truth is there simply is no fix for this. You'll have to just use a wire brush and remove the white powder - the corrosion - and then re-attach the ground. I know it's an inconvenience but it is the only thing you can do in this case.

    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.

  • Can I Ground Trailer Lights To Trailer's Main Ground
    You can ground all of the trailer lights like part # MCL36AB to the main ground on the trailer. We normally recommend to attach the grounds to a clean bare metal surface of the trailer frame for a better connection. If you have ground issues after connecting the grounds to the main ground, I recommend to ground to the frame.

  • 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 part...

  • Square LED Trailer Clearance Light Compatibility with a 24 Volt System
    I am sorry, but no, the MCL36AB LED bulb will not work with a 24 volt system. It is a 12.8 volt bulb. As far as the life expectancy, there is a lifetime warranty on the LED bulbs; but please do not attempt to use them with your 24 volt system. They will not work, and may completely compromise the system.

  • 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). If your trailer connector does not have a ground attached to the trailer frame you...

  • 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 uses...

    While we don't have a video showing how to install the Optronics Trailer Clearance or Side Marker Light w/ Reflector # MC76AB, I can tell you that the black wire needs to be connected to your trailer running light circuit and then the hardware used to mount it needs to be installed on a clean, bare-metal surface because that is how the light grounds. Similar to the attached install video of the Optronics light # MCL36AB but different in that this light actually has a ground wire.
