Features to know about

Reliable Visibility and Efficiency: 6-Diode LED Lighting

Older incandescent lights can dim, draw more power, and fail often. This rectangular LED clearance and side marker light uses six bright diodes that deliver strong, even light while pulling only 0.20 amps at 12.8V. There are no bulbs to replace and no fragile filaments to worry about. The red lens over white LEDs gives a clean, consistent glow that helps your trailer stay visible while keeping current draw low.

Built Tough for Everyday Use: Die-Cast Steel Housing

Rough roads and the occasional bump can take a toll on plastic housings. The die-cast steel body on this light protects the LEDs from impact or debris, adding real durability where it counts. It’s made to stay solid and resist damage so you’re not replacing lights after every season. That armored design makes it a dependable choice for frequent use or gear that sees hard miles.

Clear Coverage from All Angles: PC-Rated Beam Spread

Good visibility isn’t just straight ahead—it’s from the sides too. This light’s PC rating means it throws light 90 degrees to either side for a total of 180 degrees of coverage. When installed correctly, it doubles as both a clearance light and a side marker light, making it easier for others to see your trailer from multiple angles.

Simple Wiring and Mounting: 2-Wire Surface Design

Wiring doesn’t need to be complicated. This light uses a simple two-wire setup—a power lead and a ground wire—so hookup is quick and straightforward. The surface-mount design attaches directly to your trailer with hardware (not included), using mounting holes spaced 3-7/8" center to center. At 4-1/2" long by 2" wide by 1-1/2" thick, it fits neatly in place without sticking out awkwardly.

  • Beam pattern: 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.

  • Lifetime warranty on LEDs

by:

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.



by:

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



by:

Have not installed the lights yet but the initial quality looks very good. Quick and courteous shipping. So far so good.



by:

Love all the led lights I’ve purchased from trailer I would highly recommend them



by:

Very bright and just what I wanted them to be



by:

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.



by:

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



by:

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



by:

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.



by:

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.



by:

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!



by:

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.



by:

The built quality is very good, a solid feel as if it will last for many years. The light that it emits is very strong and can be seen from far away. However, the case body is already rusting and gives a horrible appearance. I would still purchase this light again but the need for a better paint job is in order.



by:

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



by:

exact match to the rest of lights on the truck, optronic lights hard to find normally.



by:

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.
Jim



by:

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.



by:

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.



by:

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.



by:

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.



by:

ALL THE LED LIGHTING FOR MY BOAT TRAILER THAT I PURCHASED WERE PERFECT.
EVERYTHING WAS PACKED NEAT AND SECURE.
NICE BRIGHT LIGHTS COMPARED TO BULB TYPE LIGHTING.

THANKS



by:

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!



by:

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.

  • 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. The LED equivalent to the # MC82RB light is the Steel Armored LED Trailer Clearance and Side Marker Light, # MCL86RB, which draws .160 amps at 12.8 volts input. I posted a video review of this light for you to check out, see link.

  • 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...
