PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

I purchased these for the side rail marker lights on our 20’ boat trailer. I liked the protection on the top and bottom of the lens. There are two lights in the picture. One on the fender and one on the side rail. I used the light that came in the kit to mark the fender and this to mark the side rail.

I am still happy with this purchase but a little disappointed too. After a year, the metal bracket is rusting which is disappointing. I’d still would recommend it to future buyers but be aware of this.

Have had these on my trailer for 9 years. Ordered a new one as a replacement for one that broke. The quality of the new one is the same as the one from 9 years ago in my opinion.


The lights I ordered from were of excellent quality and worked great. The lights are bright and were easy to install. They are an excellent replacement for my old trailer lights. I will definitely shop at for more trailer parts. The parts were shipped quickly and I am very satisfied with my purchase.

Quality product. Would definitely recommend and used again. Thank you.


Bright and strongly built. Great purchase and very pleased.


Ordered 6 lights. They arrived in good condition and were adequately protected. The lights are nice and bright. I used them in conjunction with a strobe controller on my utility vehicle for some added safety when plowing snow this winter. They were a little large in size for the application but I selected these because they were protected with steel ribs. I don't expect that these will be broken by or ripped off by any tree branches.


Plan is to install these on a 1967 Military M416 Jeep Trailer.
Most of the similar so called “armored” clearance/running lights are plastic, and I thought they would not last. These are “stout”.
Currently tying in the additional wiring for the trailer.
Cudos to Kimberly, who was very helpful in helping me find what I needed, and guiding me thru the order process.


Leaked, seem to rust and short out

You mentioned that it leaked and shorted out. Do you still have the lock? Would you be able to send a picture? The LEDs do have a lifetime warranty.

The armored clearance lights in amber and red are perfect matches to replace the older incandescant models we have on some of our vehicles and trailers. Lights are bright, and we know we can count on much less maintenance than the bulbed units. Installation was an exact match for the older units. Price was excellent as well, and with the amount we ordered, shipping was free. etrailer website is easy to navigate, and easy to buy from. Thanks!

Look and still work great.
Ed C - 07/21/2018


Had a marker light that was always giving me trouble. This LED replacement works great. Gradually changing all my trailer lights to LED. Last longer and more reliable.

All products are still performing well.

exact replacement for my broken incandescent lights. Love it!


100% satisfied


Product is great, but shipping through USPS was a horrible choice by etrailer!


Very good light for a great price! Nice heavy duty metal case with what feels/looks like a thicker than normal lens. Easy 2 wire installation and very bright!!! I welded up some custom light guards to help protect my lights, but after seeing the ruggedness of these, I think I wasted my time. Definitely recommend!

Thank you! The lights are great, no issues at all, and tough as nails!!! I have them on a 10k 6x10 dump trailer, that I beat the snot out of, gravel logging roads, mud, snow, ice, driving through brush. I just wish my trailer tires were as tough as those lights. Thanks again, and if I ever need anything for my trailers, I will be shopping etrailer!!!
John R - 11/06/2018


Just started my install of new armored led marker light s so I can’t post pics yet but the product was exactly as described and fit perfectly. Makes the upgrade for my classic race car Trailer an easy project.

The units performed perfectly. Installation was very easy and I have had no issues to address either during the install or any time during the year or so that I have had them installed
Gary R - 04/09/2020


SUPER product -- bought two of them for a re-wiring/re-lighting project on our 1986 Supra Ski Boat Trailer project. I zeroed in on these "side / marker" lights given the aluminum construction, the shield for the lenses, and the LED lights. I highly recommend this product. Keep up the Super Customer Service - - Team. (Don H, Akron, OH)


Nice product, great for cattle trailers


Fast and prompt service


Order process was clear and easy. I have purchased from etrailer before and always found products of excellent quality. I will continue to return here for all my trailer needs.

I replaced plastic side trailer marker that I broke wheeling a trash can by on the driveway. The new lights are much better looking and wont be broken! But I always expect quality from E-Trailer!
Edward L - 12/01/2018


These lights are bright and have a nice steel housing to help protect them I use a 16 foot flat bed dove tail that I use only on minor off road to access camping spots and these help to provide extra light when towing at night due to how bright the led is


A well-built, all metal lighting fixture but not renewable such as an older incandescent bulb fixture would be. Mounting holes on this unit match that of older style marker lights. If you are refitting your trailer with these lights, the major difference is this light fixture has two wires (one, a dedicated ground) coming out the exact center of the back of the fixture.


This running light is a replacement for fender -mounted originals on our dual-axel Hudson trailer. The originals were lowergrade plastic ones mounted just above a step used to step up onto the deck. No wonder our men broke both the left and right ones in one four-month period last winter. These new ones look like they have the design and beef to resist the toe of work boots going forward. Thanks eTrailer!



I have 2 trailers, one custom built 5x10 open construction trailer and one custom built tandem axle 7x14 cargo trailer, that I carefully maintain. I have been going to ETRAILER for many years because I always get fine quality products that I can trust, and incredible customer care! What else could I ask for?


Thanks again etrailer and thanks for great service, great quality and letting me know info on availability and delivery. JP. Coos Bay , Oregon.

Laura all products purchased from E-trailer have and are being used. The lights in particular are good quality, fit and finish and have exceeded my expectations. JPCoos Bay, OR.
James P - 03/12/2017


I have not put them on the trailer yet, but they are made of good quality materials it appears. They arrived in a timely fashion and were packaged well. I will update once I have installed this weekend and actually been able to see how bright in day and night they are for performance. as of right now I would have to say excellent. I would recommend at this point.

  • Mounting Hole Dimensions of the Steel Armored LED Trailer Clearance and Side Marker Light # MCL86AB
    The mounting holes of the Sealed, Steel Armored LED Trailer Clearance and Side Marker Light # MCL86AB are 3-7/8 inches apart measured on center. I attached a picture that has this and a couple other dimensions as well plus a review video. Manufacturers don't like having CAD drawings of their products floating around so we don't typically have access to them or post them.

  • Recommended Armored LED Clearance and Side Marker Lights in Amber
    The Optronics Armored LED Clearance and Side Marker Light - 6 Diodes - Steel Housing - Red Lens # MCL86RB you asked about does have the amber lens option in part # MCL86AB. These are both excellent options to have matching light housings on the front, side and rear of your trailer. I've attached an article on trailer lighting requirements to help you with locations.

  • Recommended LED Clearance Light That Can Be Submersed
    The Optronics Clearance and Side Marker Light, part # MCL86AB is sealed and considered weathertight, but is not submersible. Its design is to protect it from the elements like rain and snow and dirt. I recommend a clearance light like part # MCL85AB. These lights have a sealed lens and housing and can be submersed. This light has an amber lens and 3 LEDs. This light has one wire for power and is grounded with the mounting hardware.

  • Are Optronics Amber Marker Lights MCL86AB Submersible?
    The Sealed, Steel Armored LED Trailer Clearance and Side Marker Light # MCL86AB cannot be submersed; it is weather-tight. What you would want is something that is waterproof such as Sealed, Mini Rectangular LED Trailer Clearance # MCL85AB. You may also want to consider something like the Optronics Mini Thin Line Sealed LED Marker/Clearance Light # AL82AB which you would mount with bracket # A91OB (chrome) or # A91BOB (black). I have added video reviews of each of these products for you...

  • How to Install the Optronics # MCL86AB Clearance Light on a 2005 GMC Sierra
    Although the Optronics # MCL86AB is designed for trailers you can possibly use it on your 2005 GMC Sierra. When a clearance light only has one wire it is because it is grounded through the mounting hardware. Since the Steel Armored LED light that you referenced has 2 wires (one for power and one for ground) you would need a ring terminal like part # DW05737-1 and a self-tapping screw like part # FA1131822 for the ground.

  • Recommended LED Replacement Options for Pop-Up Trailer To Conserve Battery Life
    For your interior overhead lights, I recommend the Optronics LED RV Interior Double Dome Light with Switch - 815 Lumens # RVILL34. Then for your outdoor lights on side the Optronics Armored LED Clearance and Side Marker Light - 6 Diodes - Steel Housing - Amber Lens # MCL86AB. Then for your CO tester you can simply use a switch like the Buyers Mini Round On/Off Rocker Switch w/ Bezel - Backlit # 3376391100 to wire the 12V CO tester.

  • Armored 24 Volt Style of Amber Trailer Clearance Lights
    We have amber trailer clearance lights that are 24 volt compatible with the part # MCL66A24B but the clearance lights you mentioned will only work with 12 volt systems. For a heavy duty base similar to the light you mentioned you can also add the part # BK66DB for silver or # BK66D1B for black as well!
