Features to know about

Long-Lasting, Efficient Lighting: 2 Amber LEDs in a Compact Rectangle

This 2-1/2" x 1-1/16" mini clearance or side marker light puts out bright amber light through a clear lens while drawing just 0.046 amps at 12.8V. The two LEDs replace fragile incandescent bulbs and last up to 50 times longer. There are no filaments to break, so you get a more efficient light that stays bright and dependable without needing bulb changes.

Worrying About Water Damage: Sonically Sealed and Submersible

Built for wet conditions, the housing and lens are sonically sealed to form a single waterproof unit. That makes it submersible—perfect for trailers that see rain, road spray, or even launch ramps. No moisture sneaks in to corrode wires or damage the diodes, so the light keeps working no matter how wet things get.

Simple Electrical Setup: 2-Wire Design with 18-Gauge Leads

Wiring is straightforward thanks to the 2-wire design—one power lead and one ground wire. The light uses 18-gauge wire, with a ring terminal already installed on the ground lead for quick connection. It’s easy to hook up and keeps your wiring clean and secure.

Reliable Coverage and Compliance: P2 Rated for Clear Signal Output

The P2 rating gives you a 90-degree beam spread—45 degrees to either side of center—for clear visibility straight on. It’s DOT compliant for use as either a clearance light or side marker when properly mounted. That consistent beam pattern helps other drivers see your trailer clearly in low-light conditions.

Durable Build for Everyday Use: Polycarbonate Housing and Clear Lens

The polycarbonate housing and lens deliver strength without adding bulk. At only 5/8" thick with 1-7/8" center-to-center mounting holes, it surface mounts neatly on most flat spots. The tough materials handle vibration, moisture, and everyday wear, giving you reliable light wherever you take your trailer.

by:

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



by:

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.

Works just as good as new. Would definately purchase again.



by:

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.

Exact replacement for my ramlin trailer lights



by:

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.

One year later and still going strong.

Purchased
these because I wanted a little extra night time visibility.

Product was delivered on time and was as described.

Everything is better than I expected!

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.

Lauren was great. Replied when I was thinking about the order. Product was on time as stated.

Someone else was in charge of getting my other order, I wish I'd gotten the communication that Lauren gave and that the part was on time.

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!

by:

Quality service and good price!

They were the perfect replacement for the original lights that were on the trailer

  • Replacement Amber Side Marker Light For Wells Cargo MC122-7-TE
    Hi Jerry, that’s a great question and I’m really glad you took the time to measure first because that’s exactly how you avoid ending up with something that doesn’t line up and turns into extra work. The light part # MCL13CA2B is a really solid match for what you described. It measures 2-1/2 inches long and just over 1 inch wide at 1-1/16 inches, so it’s essentially right in line with your 2-1/2 by 1 inch light. That slight difference in width is minimal and on a Wells Cargo like yours...

  • 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.

  • 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...

  • 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,...

  • 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.

  • 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.

  • 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.

  • 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

  • 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 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.
