Features to know about

Tough Roads and Rough Conditions: Steel Armored Protection

If your trailer sees a lot of use or harsh conditions, this light is built for that life. The Optronics Armored LED Clearance and Side Marker Light uses a die-cast steel housing that shields the lens and LEDs from road debris, bumps, and scrapes. It’s weathertight too—ready to handle rain, snow, and dirt without giving in. You get the durability of steel instead of plastic, so it stays in great shape even after years of hauling.

Better Visibility Day or Night: Bright 6-Diode LED Output

Seeing and being seen are what matter most. With 6 bright white LEDs shining through an amber lens, this light does both jobs—functioning as a clearance light and a side marker when properly mounted. Those LEDs aren’t just bright; they’re efficient too, drawing only 0.20 amps at 12.8V. No bulbs to replace, no filaments to break—just solid, reliable light every time you head out at night or down dark roads.

Wider Coverage for Safety: PC-Rated 180-Degree Beam

This PC-rated light casts a 90-degree spread to each side for full 180-degree visibility. That means other drivers can see you from the front and side at once, making it perfect for marking corners or edges clearly. Mounted right, it pulls double duty as a clearance light and a side marker to keep your trailer outlined and easy to spot from multiple angles.

Simple Setup That Just Works: Surface Mount with 2-Wire Design

Installing it is straightforward. It surface-mounts with holes spaced 3-7/8" center-to-center, so it’s easy to line up on most trailer surfaces. The two-wire design keeps wiring simple—one lead for power and one for ground—and since it runs on standard 12V DC systems, there’s no guesswork involved. Once mounted, you’ve got a dependable amber marker light that looks clean and works hard every time you tow.

etrailer is always great, quick shipping. These LED marker lights are stout and will last a long time. Thank You



by:

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?



by:

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!

great looking lights and excellent quality.
shipping was also very fast and prompt.
thanks e-trailer.

Rebuilt a 10 ton flatbed trailer and upgraded the lights. These marker lights are bright and built solid! Excellent product. Thank you etrailer.



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:

Love these clearance lights they have colored leds if you loose lens they will still be red not clear lights. I have reflectors on truck & dot hasn’t fined me for no reflective lens on light



by:

The lights I ordered from etrailer.com 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 etrailer.com for more trailer parts. The parts were shipped quickly and I am very satisfied with my purchase.



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.

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

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!



by:

Nice product easy to install, very brig ht



by:

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



by:

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.



by:

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 - - etrailer.com Team. (Don H, Akron, OH)



by:

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!!!

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

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.

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.

Close to same quality as originals.



by:

These lights arrived quickly and are of the usual eTrailer quality, which is to say, excellent.



by:

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.



by:

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.



by:

Great price. great shipping and great lights for my boat trailer. I purchased four but then thought I would like to have two pull double as turn signal indicators. Sadly these great looking lights are not up to that task. Just two wires with one being a ground wire. So I have ordered a left & right side from Europe to do the job while retaining some good looks. I wish Optronics would offer these as dual function lights in this style.



by:

These lights never disappoint. They are the perfect side marker/clearance light. These let everyone know you’re hauling something behind you. Especially at night. Also at night, I can see the lights on my trailer fenders through my door mounted mirrors perfectly. Thank you etrailer!!!

  • 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!

  • 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.

  • 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.

  • 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.
