Optronics Trailer Lights - MC82AB

Highlights

  • One Light, Two Jobs: Works as both a clearance and side marker light for full visibility.
  • Built to Last: Heavy-duty steel housing shields the light from road debris and wear.
  • Easy Bulb Changes: Uses a standard 194 incandescent bulb that’s simple to replace.
  • Weather-Tight Seal: Included gasket keeps out moisture for dependable performance.
  • Secure Mounting: Surface-mount design with 3-7/8" x 13/16" hole spacing fits solidly in place.
  • Wide-Angle Coverage: PC rating provides 180° light spread for clear side and front visibility.

Features to know about

Built for Rough Roads: Heavy-Duty Steel Housing

When your trailer takes a beating from rocks or debris, this light holds up. The heavy-duty steel housing shields the bulb and lens from impact and corrosion, keeping it working even after miles of use. It’s made for demanding conditions where fragile plastic housings just don’t last.

Simple, Reliable Power: 1-Wire Ground Design

Wiring doesn’t need to be complicated. The single-wire design on this light makes setup easy—it grounds through the mounting hardware. That means fewer connections to worry about and a cleaner installation that works with standard 12V DC systems.

Stay Visible from Every Angle: PC-Rated 180° Coverage

Visibility matters, especially at night or in low light. This PC-rated light throws a 90-degree beam to each side of its centerline, giving a full 180 degrees of coverage. When mounted properly, it works as both a clearance and side marker light so you can be seen from the front or side.

Tight Seals for Wet Conditions: Gasketed Weathertight Mount

Road spray or rain can ruin a poorly sealed light. This one comes with a gasket that creates a weathertight seal when surface-mounted to the trailer. Water stays out, and the incandescent bulb keeps shining bright trip after trip.

Straightforward Maintenance: Snap-On Lens and Replaceable Bulb

No tools needed when it’s time for service. The snap-on acrylic lens pops off easily so you can replace the 194 wedge-base bulb without fuss. Quick fixes mean less downtime and more time on the road.

  • 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 All You Need to Know About the Armored Clearance and Side Marker Trailer Light

Today on This Old Trailer, we are going to install part number MC82AB from Optronics. This is their armored clearance light. This is the new one that we are going to install and this is the old one we are going to replace. It is a pretty similar design but they are two different manufacturers. This one has seen better days so we are going to replace it. The first thing you need to do is unscrew the plastic cover here. Then you have the base behind it. One has already broken off and this one will probably break when we take it off. Yep, just like that. Now you want your surface completely flat. So here is the remainder of one of the screws that was holding it in place. So we will have to grind that off. Now basically at this point, we are just going to go ahead and just mount the light to the bracket that is already on the trailer. We are just going to do this to mark our holes. We are just going to install it temporarily. Now we will take it back off. We have our mounting holes drilled out. Loosen it up. Alright we will just go ahead and take it off. 1:01

The next thing we want to do is make room for our wire. That means we will have to drill another hole out. We are going to mark from the center of this hole over to the center of the wire coming through the light. And that is around, maybe just over, an inch. Let us go ahead and mark it over about 1 inch. We will mark our hole. Come back with a 1/4 inch or so drill bit for our access hole. Now let us go ahead and reinstall out light. Now take a moment to kind of pull on the wire a little bit. If you can move the little fixture inside, it means your wire is not pinched or anything. Go ahead and cinch it down and then all we have to do is go ahead and connect our wire to our known running wire circuit. And you can use any type of attachment you want. You can solder it, tape it or, in this case, we are going to use a quick splice. Alright, with that that will finish our install of part number MC82AB from Optronics.

Exactly what I needed, fast shipping and excellent updates



by:

Easy to install and worked great on my hauling trailer!



by:

I was impressed with how heavy duty these were for the money. Holes lined up perfectly from the old lights.



by:

Bought these lights to replace my very old lights on a 79 international, quality was very good and the armor should be heavy enough to protect lenses. Would recommend to a friend



by:

Working perfect, the metal totally protects the lens. Only drawback is if you do not have the back support then the fit is not the best as only one side can be bolted down if you do not modify the support area.

The light is still working fine after 1+ years, few times I accidently bumped the light the metal does a great job of protecting the lens.



by:

Very well built. Easy swap for my older lights. After a year they are all good as new! No more bulb swapping every month.



by:

Parts stores said I could no longer get steel or metal lights, found these on line seem to work well . Thanks Charlie



by:

Fast Shipping, piece of cake to install, Thanks!



by:

Thanks etrailer. Ordering online was easy and product arrived in only a few days.



by:

Easy installation, bright light. I installed four lights on a boat trailer; one lens disappeared somewhere on the road. This may have happened because the trailer is hauled twenty miles along an unpaved levee, four days a week. Otherwise, I am well satisfied with this product.



by:

These are the the best clearance lights for my trailer I have found.



by:

They look very nice and durable, just what I wanted. They are a replacement to the very same ones I had originally on my old Chevy C30 dually. I don't know that they work properly as of yet, I did not try them out yet. The only thing I saw that could have helped some, was a necessity for wrapping them in some type of bubble plastic balloon to keep them from being thrown around Inside the Box. Otherwise, thank you.



by:

Showed up on time. It is exactly like I wanted.?works well. Only thing they could do is get people in shipping to package them properly for shipyard. By the scratches and in the box loosely, I can see the error. If I was goningbto put them on a show vehicle I would send them back. It’s an old work truck



by:

Your product is more durable than others. I had plastic housing they keep brakes.

Installation was easy. I installed the lights on a 1949 dodge truck stake bed.

Thank you so much.



by:

All my trailer lights were delivered on time and seem to be of good quality, I would recommend buying here. I am a repeat costumer and will be back! Thank you etrailer!



by:

Installed on horse trailer..Has a bit of a sharp edge .only if a horse hits the wrong way. But still protective for the light . But overall worked fine



by:

Excellent choice for all my trailer parts! Great service and delivery. etrailer is now my only source for trailer parts, and have highly recommended them to several other people. Thanks so much!!!!



by:

very happy with y order and it was delivered in a timely manner. I have not installed these lights yet but have no reason to believe they will not work. thanks to etrailer for carrying a quality clearance light instead of the cheap plastic type



by:

Great lights!!! I received them yesterday. I am completely satisfied with your lights.
I bought one yellow and one red. Very tough, strong and fully sized.
A perfect match for my existing Grumman Olson marker lights.

The original manufacturer does not have them; and the lights sold locally are about 20 percent smaller and cheaply made.
Additionally, you have wait 8 weeks to get them.

Thank you. Keep up the good work and keep selling good products.

Now I hope I can find replacement rear lights.



by:

So far I am very happy with the clearance lights. They are much better than the original lights that came with my 17ft e-z loader trailer.
They were priced fairly and were easily installed. The original lights were permanently sealed and the bulbs or lenses could not be replaced. With the MC82AB both the bulbs and lens covers can be replaced. I replaced both the original burned out unit and the other side to match.



by:

Good fit, looks great.



by:

Replaced the truck box lights on my 1948 Ford . Great quality .



by:

Exact match for the one I needed to rep lace.



by:

well made, heavy duty, took me FOREVER to find this good one like they used to make. Everything is PLASTIC! but not this one!



by:

These were purchased to replace ones on an old, i mean "classic" trailer. In the world of L E D i was happy to be able to make the exact replacement. so be aware the folks have it all... buy the one you want.
