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.

Video Transcript for Optronics Steel Armored LED Trailer Light Review

Speaker 1: Today we're going to be installing the Optronics Sealed Steel Armored LED Clearance Light. This comes in red with part number MCL86RB, and in amber with part number MCL86AB. This marker light's going to be an upgrade over your original incandescents. The LED's in it are going to be longer lasting, and more durable. It has a nice steel solid casing that goes out beyond the lens to protect it from any impacts.Typical incandescents don't last nearly as long. An LED will last roughly 50 times that of an incandescent.

Additionally, LED's use less wattage than typical incandescents, so you can make a brighter trailer with more lights. It doesn't draw any excessive current.The light measures 4 and 1/2 inches long by 2 inches tall by 1 and 1/2 inches deep. And from the center of one hole to the center of the other mounting hole, it's going to be about 3 and 7/8 inches. And when comparing this light to others on our website, such as Peterson's, part number 424200, it's going to have similar measurements, but this light's going to be significantly brighter, because it's LED and lasts a lot longer.The Peterson light will be a little easier to install, because you only need to hook up your power wire as it grounds through the mounting holes. And now that we've gone over some of the features, let's show you how to get it installed.We'll begin the installation by taking our light, connecting our power wire, which is the black one, to the power wire that's run on our trailer.

We'll use a heat shrink butt connector to do that, so we'll just crimp that on to our light, and then crimp the other end on to the power wire on our trailer.We'll now take a heat gun, which will shrink down our butt connector, and seal out any moisture and corrosion. I went ahead and run a zip tie up through the bottom of the frame, up out our hole, so we can use it to pull our ground wire back down through the bottom. This way we can attach it underneath, so it won't be seen and it'll look real nice when we're done.We just need to take that zip tie we ran, use a little piece of electrical tape here to attach it to our ground wire. We can now push in our power wire that we connected earlier, just push that into our frame there, and we're ready to start attaching our light.Line your light up where you want it to be, and then on our two center at our holes, we'll take a small drill bit and mark where that is, so we can put our screws there. I use some self-tapping screws to secure our light to our frame.

Self-tapping screws don't come included with the light, but can be picked up here at Now you do want to leave it a little bit loose so you can line up your other hole before fulling tightening it down.Now we can take another self-tapping screw and thread it into the bottom of our frame through our ground wire here. Now you can trailer up your vehicle, turn on your tail lights, and make sure everything's working properly. And with our light working properly, our trailer is now legal and ready to hit the road.And that completes our installation of the Optronics Sealed Steel Armored LED Clearance Light.

Same review as the parking lights purchased, they are bright and strongly built. Had to reach out to etrailer on an unrelated item and they had great customer service. Very pleased working with them.


Nice and bright


Much higher quality than I would have thought. Very rugged and beefy metal. Would have thought to be much lighter gauge steel but surprise, surprise! Have not installed yet but do not anticipate any issues. Have ordered now more than once from "etrailer and have not been sorry once. Good service and communication, high quality of parts and fast delivery. I am a very happy customer. Jim P. 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.


Just what I wanted sturdy metal casing am sure they will work and look great not mounted yet.


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!


Lenses fall out unless they are exactly centered. Other than that they are very nice.

I put the lights on a friends horse trailer, but havent seen it since. No news is good newa, i guess.


These lights are not for boat trailers the LED circuits are not waterproof. I disassembled and smeared silicone on the backs to water proof. Actually Im not sure how they worked on a regular trailer in a high rain situation at 70 mph.


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.





The products from etrailer were great. I took an old stock trailer, a littler and with the accessories from etrailer, one year later, that old trailer still looks like a new trailer. The etrailer accessories are great quality product.
Thanks for great products and ease in ordering.


building new camper trailer, and ordered tailights and misc, safety lites.
great looking lights and excellent quality.
shipping was also very fast and prompt.
thanks e-trailer.


Solid lights, and very bright!
these red and amber lights around my car hauler trailer to replace the junk that came with it!!!


Good high quality light. I used them to replace broken incandescent lights on my Hudson 4ton utility trailer. It wasn't a direct replacement for the old armored units because the new fixture is slightly larger but still only took about 10 minutes each to install.


I just received my lights in the mail today and immediately replaced the one problem light on the trailer. I was pleased to find it was an exact match to the lights on my trailer! I thought I would never be able to get those lights again! I was happy to find them on trailer for sale!


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.


Quick delivery, side markers seem heavy duty. Great to find wiring harnesses for mouse chewed ones. Take your time while shopping and use the filters to narrow down what your looking for.


Great well made product. Now my boat trailer marker lights are the least of my worries.


I looked at all my local suppliers, no one could help me. Looked online found what I wanted at etrailer.
The price was very competitive. Ordered the lights, arrived today. Very happy.j


Excellent service and customer care, Emily and George took care of some questions I had about a shipment I placed. Going to mount all the LED lights I purchased in a few days , I will send photos. Thanks Randy


Light is working great. Only problem was I was using it to replace the nearly identical incandescent version, and the wiring is in a different location, so had to drill a new hole in my fender to run the wiring through. Other than that, works great!


This was a replacement - because I backed down a boatramp and hit an underwarter 4x4....The construction prevented damage to my fender - so i am happy with the quality.


lens fell out

I see that our customer service department has sent you a replacement. We would love to hear your feedback once you get this item installed.



Perfect replacement for my original trailer lights. Same size and same shape.


These are really good quality. I am very happy with the service I received. I had a damaged item and an incorrect item when my order arrived. I called customer service and they sent out replacements right away.

  • Installing Side Markers That Also Serve As Turn Signals on Trailer
    If you are wanting side marker lights on your trailer that function both as side markers (running lights) and turn signals then you will need assemblies that have two power wires. The Optronics Armored LED Clearance and Side Market Light # MCL86RB that you referenced features a single power wire and a ground wire so it could not be used in this manner. You would only be able to hook it up to a single circuit such as running lights or brakes/turn signals. If you were to use this assembly...

  • What is the Amperage Rating for the Armored Trailer Clearance and Side Marker Light with 194 Bulb
    The Armored Trailer Clearance and Side Marker Light, # MC82RB, utilizes a 194 bulb like the Replacement Side Marker Light Bulb, # A194B. This particular bulb draws 2.7 amps at 14 volts input. If you need lights that draw less amperage you can use LED lights.

I posted a video review of this light for you to check out, see link.
