Video Transcript for Optronics MCL13 Series LED Lights Foam Gasket Installation

Today we're going to be taking a look at and showing you how to install a black foam gasket for MCL13 series LED lights.This is what your gasket looks like. It's going to go that extra mile to ensure a watertight seal. It's also going to give a nice foamy soft surface to put in between your light and whatever surface you may be mounting it on. The gasket will also work well if you don't have a perfectly flat surface like we have on this bracket here. A gasket can actually help fill that void when you put your light on it, as you can see there.Now I'll show you how easy it is to install our gasket. You run your wires through the center hole and then through the mounting hole.

If you're using it with a gasket and a chrome bezel, you simply put the chrome bezel over both of them, and run your wires through.Now using your existing hardware, or even some new hardware you pick up from your local store, we're going to secure our light to the trailer.That will finish up our look and install of the black foam gasket for MCL13 series LED lights.

Foam Gasket for MCL13 Series LED Lights - Black - A13G2B

Arrived on time perfect


When my clearance light quit I ordered the Optronics MCL13A2B light, the MCL13C2B chrome ring, and the MCL13G2B gasket. So this review is actually of all three products.

I wanted to make a watertight installation and actually wasn't exactly sure how to best accomplish that. So here is what I did.

1. I place the gasket on the chrome ring.
2. I ran a bead of silicone around the gasket edge inside the chrome ring.
3. I placed the LED light into the chrome ring. My objective is to create a sealed light assembly.
4. I then backed the chrome ring with butyl tape and mounted it on the trailer.

The light is sealed from the back by the butyl tape and the silicone plus the gasket keeps the water from entering from the front.

I've ordered clear caulk which I will apply on the top half of the light to further seal out water.


The price I feel Etrailer can do better. Not sure if there should be a note when using the gasket it might interfere with the ground that is built into the light.

THe lights still work well. Better than the ones the trailer came with.


I bought red and amber LED marker lights and replaced all of the old corroded ones on my boat trailer. It didn't take long and they work great!


The light and associated parts were just as described and work great. The LED's are very noticeable. Thanks e-trailer.

Still working after a year. Very pleased with product


See below


I bought these for my son's 5th wheel hitch after he saw mine and is very happy


The on-line service was great, done by David. He was so helpful. He even researched whether the product would fit. Can't thank him enough. We will certainly use etrailer again.


Have used these gaskets on both marine and utility trailers. They cushion vibration and provide clean edge detail for your lights. Recommend


Fit my ATC Toyhauler perfectly. Alyssa S spent much time on the phone with me to insure everything I ordered was correct. She is a wonderful customer service representative.


I’ve used this for about 9 months on an off-road adventure trailer, and it’s held up great. I like the design, they’re easy to install and the plastic lenses snap in snugly. I also like that they’re low profile and don’t stick out much at all. Great product.


Great products and great service from e trailer!


They do what they're supposed to which is keep the insides of the lights dry.


I would like to have a thicker gasket maybe a rubber one would work better for me because this is my lower marker light and can get a lot of water and snow.
But shipping was fast and the order was wright

thank you


These foam mounting pads protect the underlying paint and seal up nicely behind the lights.


What more can you say? It's a foam gasket for a light! I suppose it is properly cut and will suit my needs for a travel trailer perfectly!


Nice finishing touch to my LED side mar kers.


It's a foam gasket as stated. Die cut gasket does work with the LED piece.
How it holds up to the outside elements is anybody's guess.


Seems to fit and will absorb some of the road vibrations.


As described. Fast shipping



Thanks for following up. Still works great, no complaints. Will definitely purchase from you guys again.


Fits the 2 diode led light perfectly


I'm very pleased with this transaction. Product showed up as described. No surprise fees at my door, and a follow up email from George within an hour making sure I received everything. I will be returning very shortly I'm sure. Thank you very much.


Product is what it is for upgrading my boat trailer running lights. Etrailer has great product availability, very good and fair pricing and super service and fast shipping. The reasons I buy from eTrailer whenever I need cargo and boat trailer parts.

It seams to keep the water out, what more would we want.

  • What is the Distance Between the Mounting Holes on Sealed, Mini LED Trailer Light # MCL13A2B

  • Are Chrome Trim Rings and Foam Gaskets Reqired for Replacement Side Marker Lights for Boat Trailer
    The polished chrome ring, # A13C2B, is not required for mounting the sealed mini side marker lights, # MCL13A2B and # MCL13R2B. This is decorative trim ring only. The foam gasket, # A13G2B, would be used if these lights are mounted on the outside of an enclosed trailer, to keep out water and road grime. The foam gasket also provides some cushioning that may increase the life of the side marker lights. For your boat trailer the foam gasket would not be required but might be a good idea...

  • Is Sealant Required to Install Sealed, Mini LED Marker, Clearance Light # MCL-13CA2B
    The light itself, # MCL13CA2B, is sealed so no worries of moisture getting into it. For the holes in the trailer to mount the light you could go with a silicone sealant such as # LT37467 which would be better than the foam gasket, # A13G2B. A combination of the gasket and silicone around the mounting holes and using the trim ring, # A13C2B, would be the best solution.

  • How Long is the Mounting Bolt on the Optronics LED Clearance Light # MCL95AB
    The bolt on the back of the clearance light # MCL95AB is approximately 5/8 inches long from the back of the light housing to the end of the bolt. Not all bolts on lights equipped with them are the same length but they are generally within very close proximity, no more than 1/4 inch off, from the lights I have measured. The stud in this light is also the grounding point. Similar lights, like # MCL13A2B, would mount using 2 screws with gasket # A13G2B. This light has 2 wires so you would...
