Optronics MCL63 Series Miro-Flex Amber LED Marker Clearance 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.

Nice lights- they plugged right into the existing light sockets and are much brighter. They seem to be holding up well against wet and snowy weather.

Lights were exactly what I needed to lower the total draw from the 15 running lights on my trailer that kept blowing out the fuse on my Honda Pilot. And they are brighter than the old style. Easy to install - just pops right in. Thanks

  • Replacement Clearance Light for 1997 Champion Bass Boat
    The Miro-Flex Thinline LED Trailer Clearance or Side Marker Light # MCL63AB that you referenced will work great as a replacement for the clearance light on your trailer frame currently. For a mounting bracket that includes the wiring you'd want the part # A65PB and you'd be set.

  • Do I Have to Replace the Wedge Lights on my Boat Trailer with Wedge Lights for LED Upgrade
    When replacing trailer lights (with or without LED) you don't necessarily have to get the exact same light or even light style. Most people like to keep the same style and size so that they don't have to mess with repainting or making sure that everything lines up correctly. If your current light has the same dimensions of the Peterson Sealed Wedge-Type Clearance Marker w/Reflex # M116A then the Optronics Sealed, Miro-Flex, Thin Line, LED Trailer Marker # MCL63AB has slightly different...

  • How to Pick Out Trailer Hubs for Older Dilly Trailer
    In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. I wish there was a way to find out what you need based solely on trailer info that you gave, but that's not something that's readily available. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. Next thing you...

  • Is a Base Required for Mounting the # MCL63AB and # MCL75AB Trailer Side Marker Lights
    Yes, a mounting base is necessary for the # MCL63AB, you will need to use either the Black Bracket and Single Wire Plug, item # A65PB, or the Chrome Bracket and Single Wire Plug, item # A67CB with this light. The # MCL75AB, Thin Line Trailer lights also require a mounting base. Brackets for the # MCL75AB include the # A65PB and the # A67CB bases, mentioned for the # MCL63AB light.

  • Installing Optronics LED Trailer Marker # MCL63AB on Trailer
    In order to install the Optronics Sealed Micro-Flex Thin Line LED Trailer Marker # MCL63AB on your trailer, you will need to add a bracket and wire harness, such as the Black Bracket with Single Wire # A65PB or the Gray Bracket and Single Wire Plug # A66PB. The choice between the two brackets is simply based on color preference, as they will wire and install the same way. The bracket will ground through its hardware, so it just needs a single wire to power the light. You will want to...

  • Is the Optronics Micro-Flex LED Clearance Light Both a Light and Reflector
    My contact at Optronics confirmed that the # MCL63AB Sealed Micro-Flex Light is only a clearance light and not also a reflector. The reflective geometric design in the lens is to help to increase the light output of the LED. It will not really reflect much light that will happen to shine at the lens.

  • Recommended White LED Utility Light Similar to Optronics # MCL63AB
    The closest option we have available to the Optronics Micro-Flex Thinline LED Clearance Light # MCL63AB that uses a white lens is with the Optronics Thinline LED # UCL65CB. This waterproof rectangular LED light has overall dimensions of 4 inches long, 1-1/4 inches wide, and 1 inch deep. Its 6 LED diodes should give you a much brighter and longer lasting unit compared to your existing incandescent models. This will work great to light up your entry steps and sewage connections.

  • Chrome Base Recommendation for the Optronics Clearance Light # MCL63AB
    Yes, the Chrome Bracket and Single Wire Plug # A67CB that you referenced is the correct base for the # MCL63AB and # MCL63RB that you plan on getting. The reason this bracket uses a single wire is because the light will ground through the mounting hardware. If you needed to run a second ground wire to the assembly you would only need to run the stripped ground wire around the mounting screw that attaches to the side of the base with the ground strap. See picture I attached to see which...

  • What is Difference between Miro Flex and Thin Line Optronics Clearance Lights
    The Miro-Flex part # MCL63AB and the Thin Line part # MCL75AB are both very similar. They essentially are just visual differences for the lens. The Miro Flex has more of a Euro style look where you can see the diodes and the reflective base in the light whereas the Thin Line has the diodes obscured. Both would work well and I would recommend you pick which you like the appearance of more.

  • Replacing 5th Wheel LED Marker Light Not Working
    The Miro-Flex Thinline LED Trailer Clearance or Side Marker Light - Submersible - 4 Diodes - Amber Lens # MCL63AB can't have the inside replaced. You would need to replace the entire LED light. Before replacing the light, you want to make sure you don't have a wiring issue. You can test the light with a 12v battery or you can test the wires using a circuit tester like # 40376.

  • Will Thin Line Clearance Light # MCL63AB Work with a Mounting Bracket # A67CB on Aluminum Trailer
    Yes, the Chrome Mounting Bracket # A67CB that you referenced will work on your aluminum trailer with the Clearance Light # MCL63AB, but since you have an aluminum trailer and the bracket grounds through the mounting hardware you will also need a Two Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights # A68P.
