Optronics MCL13 Series LED Clearance Marker Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Very bright and nice lights along with a great lifetime warranty!


The led light are bright and work well for the most part. I have changed a few in the last couple of years. The housing on some are not quite sealed properly. Water gets in and out they go. 1 of 3 lights replaced worked for a few months and then water found its way in.
Overall they or good. If you rtv the seams and seal them yourself, they will last a long time.


Was looking for an exact match to replace a few of my clearance lights on my trailer.
With the help of a young lady on the customer assistance line, she found the perfect match!
Received the lights yesterday, and mounted perfectly in the same spot as my old ones.
Thanks for the outstanding customer service!


Good replacement parts. Company provided tracking number and updates.


The LED marker lights were exactly what I was looking for. Installation was quick and easy. Great product. Great service.



Follow-up, one year later. The LED marker lights are performing great. the lights are just as bright as new with no discoloration. Excellent product.


The lights are awesome. I used four of the amber and two red ones for clearance lights on a trailer that i built for a friend, along withe the clear lens tail and turn lights made for a hreat look. Very happy with etrailer and there service. I will reorder for my next project for sure. Thanks


Direct replacement for my trailer. Easy install.


I love these lights. They compliment the other leds on my truck and camper. I installed these on the running boards.


I purchased 3 of these lights to build a "raptor" style grill light system for my 2016 F350. They are a perfect match to the factory Ford running lights and work great!


These lights were exactly as described. They are extremely bright for the size. Highly recommended for any body looking to add style and brightness for there trailer.


These little lights are fantastic! They're small, but very bright. I bought these LED marker lights to replace the other LED marker lights (on my aluminum boat trailer) that actually broke because they used the mounting screw as the ground. The plastic became brittle and broke away from the screw on one of the lights and it just dangled by the brown wire.
I specifically bought these lights because they have two wires instead of a mounting screw for ground -- and they were cheaper! I just rewired my entire trailer and ran a separate ground wire to each light, thus removing all grounding from the trailer, and using the truck as ground. Now I don't have to worry about the effects of electrolysis or galvanic corrosion when I dunk my trailer in the salt water since I removed any chance of potential.
Just for cosmetic reasons, I also mounted these lights onto small pieces of plastic (Starboard) before I mounted them to my trailer.
Unfortunately, it's raining right now so I'm not going to submit any pictures of my installation.

Fantastic1 i couldnt be happier with these lights. I use my boat a LOT and Ive had zero problems. None!


One year later and still going strong.

these because I wanted a little extra night time visibility.


I use these lights to help see my tires at night on my camper. They are mounted on the bottom of camper between the axles. Mounted here they get all of the road spray and rocks coming off of the tires. They are holding up well, there is no moisture in the lens at all. As a added benefit they help when setting up at night. You are able to see where to put the leveling blocks and chocks without a flashlight. I would buy these again when needed.


Excellent little lightIn case it was missed in the description this is a 2 LED light. The lens spreads the light acceptable and it makes a great running light.
The wires are attached right next to each other directly in the center of the back of the light making extensive drilling and connectors unnecessary. I do wish that black machine mounting screws were available as the screw wholes are a slightly odd shape (tough usable).
Light output is great for nighttime operations and will drastically increase visibility over a reflector but do not expect super bright daytime operation.
Also if the unit does not appear to work try switching the leads my black was power with white as ground. A bit odd but not a real problem.


Well sealed unit. Exact match for other lights on my trailer. Added more side lights for increased visibility.


I used these on my running boards. They look great and have been functioning flawlessly.


Thanks for the opportunity to comment regarding the recent order from "etrailer" for your lighting products. The items arrived in good condition. The items seem to as advertised. It's very nice to have an organization such as yours to meet the needs of the motoring/trailering community. Your prices are reasonable and your products are of excellent quality.


Used these as marker lights along the bottom of the rockers on my pickup. Have been working and looking great for a year now. They do get some moisture in them, but doesn’t seem to affect them so far.


Just as pictured!


I have not had these lights very long, but them seem to be high quality. And at just under 50mA each, the circuit load will be substantially reduced with this upgrade.
Rated 4 stars since I have yet to evaluate their durability.


I replaced the lights on my boat trailer one year ago and haven’t had one go bad yet.


Perfect fit!


As described. Just what I needed. The exact dimensions helped choose the correct item, so that I did not have to drill more holes!!

Wanted toads more to our trailer and they are awesome. Love etrailer products.


fit well. looks good

  • Availability of a Clear LED Trailer Clearance Side Market Light
    The closest match we have to the mini rectangular LED trailer clearance trailer side marker light # MCL95AB is the Optronics sealed, LED mini utility light # UCL13C2PG. It's 2-1/2 inches long and 1-1/16 inches wide. Other potential options to consider: # MCL13CA2B # MCL63CAB # MCL65CAB # AL91CAB I included an informative article and several video reviews too.

  • Recommended Trailer Clearance Light With Clear Lens
    We do offer a clearance and side marker lights that may work for you. I have attached a helpful article that explains trailer lighting and what is required. One clearance light with a clear lens I recommend is part # DG52530VP. This is a surface mount light that has a clear lens with white diodes and a thin black base. This is a 2-wire light and measures 2-5/8 inches L x 1-1/4 inches W x 3/4 inch H. Another clearance light we offer with a clear lens that has 2-LED amber diodes is part...

  • Trailer Amber Clearance Light with a Clear Lens
    Replacement lenses are not available for the MC71 series of trailer lights. The remaining option is to replace the whole light. For something that has a clear lens with amber lights you will need to use an LED light such as: # MCL63CAB # MCL13CA2B # MCL65CAB # AL91CAB

  • Availability Of 2-1/2" x 1" LED Trailer Clearance Light
    I have a different option for you, but I was unable to find a light that matches the one you pictured with green diodes. The closest options are the LED Trailer Mini Clearance or Side Marker Light - Submersible - 2 Diodes - Amber LEDs - Clear Lens # MCL13CA2B which has amber LEDs, or the # MCL13CR2B which has red LEDs. I included videos for each of the products mentioned for you to take a look at.

  • Red and Amber Trailer Clearance Lights with Clear Lenses
    You are correct, clear lenses are not made for lights # MC32AB or # MC32RB. The bulbs for both of these lights produce white light so if clear lenses were on them the light would just be white. Unless you found colored bulbs that would fit. We do have red and amber marker/clearance lights with clear lenses though. For example we have # MCL63CAB which is an amber LED light with a clear lens. Other amber options include # MCL13CA2B, # MCL51CAK, # MCL65CAB, # AL91CAB, # MCL17CAB, # 00212336P,...

  • 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.

  • Is the Sealed LED Mini Utility Light Waterproof and Submersible
    The Sealed, LED Mini Utility Light, # UCL13C2PG, is a sealed unit, and is considered waterproof, so it could be submersed. This light is designed as a utility light and would require a separate switch to activate the light so it would not be illuminated when the trailer is being towed. We also have the Sealed, Mini LED Marker, Clearance or Identification Light, # MCL13CA2B in amber and # MCL13CR2B in red, that are designed for connection to the trailer running light circuit. As with any...

  • What Gauge Wire Would be Required for Trailer with LED Clearance Lights that Draw 3.3 Amps
    Even thought that is a quite a few LED lights on your trailer the amount of amperage draw total for all circuit would be 3.35 amps. That's well below what standard lights would draw on trailers with just a handful of incandescent lights. You would easily be able to get away with 14 gauge or even 16 gauge wire.

  • What Gauge Wire Is On The Optronics Mini Clearance Light MCL13CA2B?
    The Optronics LED Trailer Mini Clearance or Side Marker Light # MCL13CA2B will use 18 gauge wire. The ground wire does have a ring terminal pre-installed, but depending on how many lights you need, we do have the 5-Pack Deka Heat Shrink Butt Connector - 22-18 Gauge # DW05743-5 that will work perfectly with this light.
