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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL13CR2B Review

Today we're going to be taking a look at part number MCL 13CR 2B, this is Uptronics sealed mini LED marker Clearance Identification Light. It's going to feature a consistent even spread of light output and again it's going to serve as a clearance side marker or identification light. LEDs are going to be great replacements for incandescent lights, you don't have to worry about replacing bulbs and you don't have to worry about burned filaments 00:22. This is going to have two red LEDs with a crystal clear lens. It's going to have a nice sealed water proof housing and LED unit. It is a service mount design.

We take a measurement the distance that we have between those mounting holes. It's going to be two of them here on the back of the housing. That's is going to give us a measurement of about 1 and 787 inch. The two wire design is going to include your wires for power, it's going to be a black wire and for ground it's going to be a white wire with the attached ring terminal on there. Again, two red LEDs. The overall length of the light measuring from edge to edge, that's going to give some measurement of about two and a half inches long.

The over all width, at the widest point looks to be 1 and 1 168 7 01:11 inch and then the overall depth, that's going to give us a measurement of about 11 16 7 inch. That's the LED light it's going to draw 0.046 Amps at 12.8 Volts. It's Department Of Transportation approved, and Uptronics is going to put a lifetime warranty on the LEDs. It's good to hook it up to an extra power source, so that we can see what it looks like with power running through it. So you can see here the two red LEDs, nice bright light, very consistent light output, and that crystal clear lens allows a lot of light to come through you. Again this is going to serve as your clearance side marker, or identification light. That's going to do it for a review of part number MCL 13 CR 2B.

This is the Uptronics sealed mini LED marker clearance or identification light. .

Improved the visibility of my construction rack. 870146


Small light but it put out good light for it to be small and easy to install 821793


I bought amber & red and like them both .. 699296


Clearance light went out on my RV after 10 years. This was EXACTLY what I was looking for and at a great price so I ordered an extra. 669609

Withstood the west Texas weather just fine.

Great product perfect for my trailer 667224

Great lights

They work just as good as the day I installed them!!!! 635346


Good product 606704

Works great. Matches the factory lights on my trailer
John C - 02/21/2020



Good maker light. 498586


I have not had these lights for very long, but they seem to be of good quality. And at just under 50mA each, circuit load on the trailer will be cut substantially with this upgrade. Rated only 4 stars since I have yet to see their durability. 453286


Great products, great service 387828


Exactly what I want very good product great people to deal with 329700


Got them fast and look awsome on my car trailer 278758


Easy hookup works great. 253529


These lights are great and super bright. Clear when off, and red when on. I have also used the amber and white lights off the same style and shape. The amber ones are also super bright, but the white lights are not very impressive. I recommend the red and amber, but steer clear of the white lights. 251911


Nice and bright. The clear shell gives these a nice custom look to my cargo trailer. Two of my 10 lights have developed leaks in the shell. I don't know whether that will lead to early failure of the LED. Time will tell. Excellent service and support by e-trailer. Thanks! 125510

All of the LEDs are working well after one year. Im still very happy with them. They male the trailer look great. The moisture in the housing is still there but has not affected the operation.

Product was excellent and delivery was phenomenal. 115817


Ask the Experts about this Optronics Trailer Lights

  • Recommended Replacement Step Light for 2017 Forest River EVO Travel Trailer
    The Sealed, Mini LED Marker, Clearance or Identification Light, 2 Wire, 2 Diode - Red w/ Clear Lens # MCL13CR2B is 2-1/2 inches wide and 1-1/16 inches tall. For a similar clear light, I recommend the Mini LED Trailer Clearance or Side Marker Light - Submersible - 1 Diode - Clear Lens - Amber # MCL99AC1B. With the amber LED, you still can see for your steps. I've attached a video to assist.

  • 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,...

  • 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.

  • Clear Submersible LED Trailer Light Recommendation
    For a similar LED light as the CIPA EVO light part # CM93236 that you referenced that is submersible and would be great for a boat trailer I would recommend the Uni-Lite Mini LED Side Marker/Clearance Light w/ Grommet part # MCL11CAKB. This is flush mount light. Another option that is a surface mount would be the Sealed, Mini LED Marker, Clearance or Identification Light # MCL13CR2B. The # CM93236 is designed to fit into a vehicle bulb socket, so not only would it not be submersible...

  • 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.
