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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL63AB Review

Today we're going to be taking a look at the Optronics sealed Miro-Flex thin-line LED trailer marker, clearance, or identification light. Now this light contains a total of four amber LEDs. It's also going to feature to Miro-Flex technology that increases light output while using 90% less energy than incandescent bulbs. It has a really nice contemporary appearance while maintaining the traditional footprint. This LED light draws 0.051 amps at 12.8 volts. That's a full LED system.

LEDs are going to make great replacements for incandescent lights. They last longer, they burn brighter, and they're much more efficient. You don't have to worry about replacing bulbs or worry about inaudible 00:00:41 filaments. This units going to feature a really nice sealed, waterproof lens and housing. Now, when mounting, you will need to use an existing or new mounting bracket. I recommend using part number A65PB.

This is available here at etrailer.com. It mounts on three inch centers. The light simply snaps into the bracket. The light grounds through one of the mount holes, so it grounds through the mounting hardware, and then the bracket offers a single wire which functions as a power wire. That is sold separately.

Again, available at etrailer.com with part number A65PB. Taking a look at some of the dimensions real quick of this light, it's going to measure three and 15/16 inch long, an inch and a quarter wide, and the depth of the light is about 7/8 inch deep. It is SAE and Department of Transportation compliant, and Optronics puts a lifetime warranty on the LEDs. We're going to go and hook it up to power, so I'm going to go ahead and take the prongs right here and engage those and the holds right there on the bracket. Then the unit simply just snaps together, holds the light securely in place. Now this light sends out a very clear, consistent signal.

Again, it's going to contain a total of four LEDs. Gives the unit a really nice look. The multi-diode design really helps optimize the light output of the unit. That's going to do it for today's look at the Optronics sealed Miro-Flex thin-line LED trailer marker, clearance, or identification light.

Perfect fit for my Trails West Sierra II horse trailer rear side marker light. My horses somehow bit off the original and this was the exact same fit. Trailer is the only place I could find these types of lights. Just sad the shipping had to cost more than the light itself 462582

Review from a similar Optronics Miro-Flex Thinline in Trailer Lights


These LED Miro-Flex lights are a proper upgrade. They really look SHARP! My truck is grey, my trailer is grey, I replaced all the marker and tail lights on my 09' 7x14 tandem HaulMark with these and now have better visibility during the day. After a year i still am very happy. I noticed the lights are directional, so if your at the side during the day you have to look at them straight on to see if they are working but thats really not an issue. You have markers on all four sides just for that reason as well as reflectors. I have actually gotten unsolicited compliments from other contractors on the trailer since i got these. 272923

Very pleased with the thin Miro- flex side markers. I put them on my 2001 dodge dually and man are they bright. I only wish they offered them in 2 1/2 too. But over all they are well worth buying if your looking for good looking lights on or off. 384016

Review from a similar Optronics Miro-Flex Thinline in Trailer Lights


It appears that this will be an excellent light after I receive all of the additional parts to actually install the lights. I ordered 14 of these lights only to find out after receipt they require the mounting brackets and plug in. Thus delaying the project and incurring freight cost because the order is under the threshold for free shipping. I upgraded the freight to ground only to find out that etrailer didn't have the part of my additional parts in stock. Jury still out on this project. 559531

Do you have a question about this Trailer Light?


  • 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...

  • 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.

  • 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...

  • 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.

  • 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...

  • 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.

  • 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.

  • 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.
